Lustrum

XII

For the first few weeks after he ceased to be consul, everyone clamoured to hear the story of how Cicero had foiled the conspiracy of Catilina. There was not a fashionable dinner table in Rome that was not open to him. He went out often; he hated to be alone. Frequently I would accompany him, standing with other members of his entourage behind his couch as he regaled his fellow diners with extracts from his speeches, or the story of how he had escaped assassination on polling day on the Field of Mars, or the trap he had set on the Mulvian Bridge for Lentulus Sura. Usually he illustrated these tales by moving plates and cups around, in the manner of Pompey describing an old battle. If someone interrupted him or tried to raise another subject, he would wait impatiently for a gap in their conversation, give them a hard look and then resume: ' As I was saying…' Every morning the grandest of the grand families would flock to his levees and he would point to the very spot where Catilina had stood on the day he offered to be his prisoner, or to the exact pieces of furniture that had been used to barricade the door when the conspirators laid siege to the house. In the senate, whenever he rose to speak, a respectful hush fell over the assembly, and he never missed a chance to remind them that they were only meeting together at all because he had saved the republic. He became, in short – and whoever would have imagined saying this of Cicero? – a bore.

It would have been so much better for him if he had left Rome for a year or two to govern a province; his mystique would have grown with his absence; he would have become a legend. But he had given away his governorships to Hybrida and Celer and there was nothing for him to do except to stay in the city and resume his legal practice. Familiarity makes even the most fascinating figure dull: one would probably be bored with Jupiter Himself if one passed Him on the street every day. Slowly Cicero's lustre faded. For several weeks he busied himself dictating to me an immense report on his consulship, which he wanted to present to Pompey. It was the size of a book and justified his every action in minute detail. I knew it was a mistake and tried all the tactics I could think of to delay sending it – to no avail. Off it went by special courier to the East, and while he awaited the great man's reply, Cicero set about editing and publishing the speeches he had delivered during the crisis. He inserted many purple passages about himself, especially in the public address he had made from the rostra on the day the plotters were arrested. I was sufficiently worried that one morning, when Atticus was leaving the house, I drew him aside and read out a couple of sections.

' This day on which we are saved is, I believe, as bright and joyous as the day on which we were born. And just as we thank the gods for the man who founded this city, so you and your descendants will be able to hold in honour the man who has saved the city.'

'What?' exclaimed Atticus. 'I don't remember him saying that.'

'Well he didn't,' I replied. 'For him to have compared himself to Romulus at such a moment would have seemed absurd. And listen to this.' I lowered my voice and looked around to make sure Cicero was nowhere near. ' In recognition of such great services, citizens, I shall demand of you no reward for my valour, no signal mark of distinction, no monument in my honour, except that this day be remembered for all time, and that the immortal gods should be thanked that there have arisen at such a moment in our history two men, one of whom has carried your empire to the limits not of earth but of heaven, and one who has preserved the home and seat of this empire… '

'Let me see that,' demanded Atticus. He grabbed the speech from my hands and read it through, shaking his head in disbelief. 'Putting yourself on the same level as Romulus is one thing: comparing yourself with Pompey is quite another. It would be dangerous enough if someone else said it about him, but for him to say it about himself…? Let's just hope Pompey doesn't get to hear of it.'

'He's bound to.'

'Why?'

'I've been ordered to send him a copy.' Once again I checked that no one was listening. 'Forgive me, sir, if I am speaking out of turn,' I said, 'but I'm becoming quite concerned about him. He's not been the same since the executions. He isn't sleeping well, he won't listen to anyone, and yet he can't bear to spend even an hour by himself. I think the sight of the dead men has affected him – you know how squeamish he is.'

'It's not his delicate stomach that's troubling him, it's his conscience. If he were entirely satisfied that what he did was right, he wouldn't feel the need to justify himself so endlessly.'

It was a shrewd remark, and I feel sorrier for Cicero in retrospect than I did at the time, for it must be a lonely business trying to turn oneself into a public monument. However, by far his greatest folly was not the vainglorious letter to Pompey, or the endless boasting, or the amended speeches: it was a house.

Cicero was not the first politician, and I am sure he will not be the last, to covet a house beyond his means. In his case the property was the boarded-up mansion on the Palatine next to Celer's on Victory Rise that he had noticed when he went to persuade the praetor to take command of the army against Catilina. It now belonged to Crassus, but before that it had been the property of the immensely wealthy tribune M. Livius Drusus. The story went that the architect who built it had promised Drusus he would make sure he was not overlooked by any of his neighbours. 'No,' responded Drusus, 'rather construct it so that all my fellow citizens may see everything I do.' That was the sort of place it was: high up on the hill, tall, wide and ostentatious, easily visible from every part of the forum and the Capitol. Celer's house was on one side of it, and on the other was a large public garden and a portico that had been put up by Catulus's father. I do not know who planted the idea of buying the house in Cicero's head. I fancy it might have been Clodia. Certainly she told him over dinner one night that it was still on the market and that it would be 'wonderfully amusing' to have him as a next-door neighbour. Naturally that was enough to set Terentia dead against the purchase from the start.

'It is modern and it is vulgar,' she told him. 'It is a parvenu's idea of where a gentleman might live.'

'I am the Father of the Nation. The people will like the idea that I am looking down on them in a paternal manner. And it's where we deserve to be, up there among the Claudii, the Aemilii Scauri, the Metelli – the Ciceros are a great family now. Besides, I thought you hated this place.'

'It's not moving in principle I object to, husband; it's moving there. And how can you possibly afford it? It's one of the largest houses in Rome – it must be worth at least ten million.'

'I shall go and talk to Crassus. Maybe he'll let me have it cheap.'

Crassus's own mansion, which was also on the Palatine, was deceptively modest on the outside, especially for a man who was rumoured to have eight thousand amphorae filled with silver coin. Inside he sat with his abacus and his account books and the team of slaves and freedmen who ran his business interests. I accompanied Cicero when he went to see him, and after a little preliminary talk about the political situation, Cicero broached the subject of the Drusus house.

'Do you want to buy it?' asked Crassus, suddenly alert.

'I might. How much is it?'

'Fourteen million.'

'Ouch! That's too expensive for me, I fear.'

'I'd let you have it for ten.'

'That's generous, but it's still out of my range.'

'Eight?'

'No, really, Crassus – I appreciate it, but I should never have brought the subject up.' Cicero started to rise from his chair.

'Six?' offered Crassus. 'Four?'

Cicero sat down again. 'I could possibly manage three.'

'Shall we settle on three and a half?'

Afterwards, as we were walking home, I tried gently to suggest that taking possession of such a house for a quarter of its true value would not go down well with the voters. They would smell something fishy about it. 'Who cares about the voters?' replied Cicero. 'I'm barred from standing for the consulship for the next ten years whatever I do. In any case, they need never know how much I paid for it.'

'It will get out somehow,' I warned.

'For gods' sake, will you stop lecturing me about how I am to live? It is bad enough hearing it from my wife, without taking it from my secretary! Haven't I earned the right to some luxury at long last? Half this town would be nothing but charred brick and ashes if it weren't for me! Which reminds me – have we heard back from Pompey yet?'

'No,' I said, bowing my head.

I let the matter drop, but I continued to be troubled. I was absolutely certain that Crassus would expect something in return for his money; either that, or he hated Cicero so much he was willing to forfeit ten million simply to make the people envy and resent him. My secret hope was that Cicero would come to his senses in a day or two, not least because I knew that actually he did not have three and a half million sesterces, or anything like it. But Cicero always took the view that income should adjust to meet expenditure rather than the other way round. He had set his heart on moving up to Victory Rise to dwell among the pantheon of the great names of the republic, and was determined to find the cash somehow. He soon discovered a way.

Almost every day at this time one of the surviving conspirators was to be found on trial in the forum. Autronius Paetus, Cassius Longinus, Marcus Laeca, the two would-be assassins Vargunteius and Cornelius, and many more passed through the courts in a dismal procession. In each case Cicero was a witness for the prosecution, and such was his prestige that a word from him was invariably sufficient to sway the court. One after another they were found guilty – although, fortunately for them, because the emergency was now over, they were not sentenced to death. Instead, each was stripped of his citizenship and property and sent destitute into exile. Cicero was feared and hated by the conspirators and their families almost more than ever, and it remained necessary for him to go around with guards.

Perhaps the most keenly awaited trial of all was that of Publius Cornelius Sulla, who had been immersed in the conspiracy right up to his noble neck. As the date for his hearing approached, his advocate – inevitably it was Hortensius – came to see Cicero.

'My client has a favour to ask of you,' he said.

'Don't tell me: he would like me to refuse to appear as a witness against him?'

'That's right. He's entirely innocent and has always had the highest regard-'

'Oh, spare me all the hypocrisy. He's guilty and you know it.' Cicero scrutinised Hortensius's bland face, weighing him up. 'Actually, you can tell him I might be willing to hold my tongue in his particular case, but on one condition.'

'And what is that?'

'He gives me a million sesterces.'

I was making my usual note of the conversation, but I must say my hand froze when I heard that. Even Hortensius, who after thirty years at the Roman bar was not shocked by much, looked taken aback. Still, he went off and saw Sulla and came back later that same day.

'My client wishes to make a counter-offer. If you are willing to give the closing speech in his defence, he will pay you two million.'

'Agreed,' said Cicero without any hesitation.

There is little doubt that if Cicero had not struck this bargain, Sulla would have been condemned to exile like all the rest; indeed, it was said he had already transferred a large part of his fortune abroad. So when, on the opening day of the trial, Cicero turned up and sat on the bench reserved for the defence, the prosecuting counsel, Torquatus – an old ally of Cicero – could hardly contain his fury and disappointment. In the course of his summing-up he made a bitter attack on Cicero, accusing him of being a tyrant, of setting himself up as judge and jury, of having been the third foreign-born king of Rome, after Tarquin and Numa. It was painful to hear, and worse, it drew some applause from the spectators in the forum. This expression of popular opinion penetrated even Cicero's carapace of self-regard, and when the time came for him to deliver the closing speech he did venture a kind of apology. 'Yes,' he said, 'I suppose my achievements have made me too proud and bred in me a sort of arrogance. But of those glorious and deathless achievements, I can say only this: I shall be amply rewarded for saving this city and the lives of its citizens if no danger falls upon my person for this great service to all mankind. The forum is full of those men whom I have driven from your throats, gentlemen, but have not removed from mine.'

The speech was effective and Sulla was duly acquitted. But Cicero would have done well to heed these signals of a coming storm. Instead, such was his delight at raising most of the money he needed to buy his new house, he quickly shrugged off the incident. He was now only one and a half million short of the full sum, and for this he turned to the moneylenders. They required security, and therefore he told at least two of them, in confidence, of his agreement with Hybrida and his expectation of a share of the revenues from Macedonia. It was good enough to clinch the deal, and towards the end of the year we moved in to Victory Rise.

The house was as grand inside as out. Its dining room had a panelled ceiling with gilded rafters. In the hall were golden statues of young men, whose outstretched hands were designed to hold flaming torches. Cicero swapped his cramped study, where we had spent so many memorable hours, for a fine library. Even I had a larger room, which, though it was below ground, was not at all damp, and had a small barred window through which I could smell the flowers in the garden and hear the birdsong early in the morning. I would have preferred to have had my freedom, of course, and a place of my own, but Cicero had never mentioned it, and I was too bashful – and in a curious way, too proud – to ask.

After I had laid out my few belongings and found a hiding place for my life savings, I went and joined Cicero on a tour of the grounds. The colonnaded path took us past a fountain and a summer house, under a pergola and into a rose garden. The few blooms left were fleshy and faded; when Cicero reached out to pluck one, the petals came away. I felt that we were under inspection from the whole of the city: it made me uncomfortable, but that was the price one paid for the open view, which was indeed amazing. Beyond the Temple of Castor one could clearly see the rostra, and beyond that the senate house itself, and if one looked in the other direction one could just about make out the back of Caesar's official residence. 'I have done it at last,' said Cicero, gazing down at this with a slight smile. 'I have a better house than he has.'

The ceremony of the Good Goddess fell as usual on the fourth day of December. It was exactly a year since the arrest of the conspirators and just a week after we had moved into our new quarters. Cicero had no appointments in court; the senate's order of business was dull. He told me that for once we would not be going down into the city. Instead we would spend the day working on his memoirs.

He had decided to write one version of his autobiography in Latin, for the general reader, and another in Greek for more restricted circulation. He was also trying to persuade a poet to turn his consulship into a verse epic. His first choice, Archias, who had done a similar job for Lucullus, was reluctant to take it on; he said he was too old at sixty to do justice to such an immense theme. Cicero's preferred alternative, the fashionable Thyillus, replied humbly that his meagre skills as a versifier were simply not up to the task. 'Poets!' grumbled Cicero. 'I don't know what is the matter with them. The story of my consulship is an absolute gift to anyone with the slightest spark of imagination. It is beginning to look,' he continued darkly, in a phrase that struck fear into my heart, 'as though I shall have to write this poem myself.'

'Is that altogether wise?' I asked.

'What do you mean?'

I felt myself beginning to sweat. 'Well, after all, even Achilles needed his Homer. His story might not have had quite the same – what should one say? – epic resonance if he had told it from his own point of view.'

'I solved that problem in bed last night. My plan is to tell my tale in the voices of the gods, each taking it in turn to recount my career to me as they welcome me as an immortal on to Mount Olympus.' He jumped up and cleared his throat. 'I'll show you what I mean. Torn from your studies in youth's early dawn, your country recalled you, Giving you place in the thick of the struggle for public preferment; Yet in seeking release from the worries and cares that oppress you, Time that the state leaves free you devote to us and to learning…'

Dear heavens, it was terrible stuff! The gods must have wept to hear it. But when the mood seized him, Cicero could lay down hexameters as readily as a bricklayer could throw up a wall: three, four, even five hundred lines a day was nothing to him. He paced around the great open space of his library, acting out the roles of Jupiter and Minerva and Urania, the words pouring out of him so freely I had difficulty keeping up, even in shorthand. When eventually Sositheus tiptoed in and announced that Clodius was waiting outside, I must confess I was greatly relieved. By now it was quite late in the morning – the sixth hour at least – and Cicero was so seized by inspiration he almost sent his visitor packing. But he knew that Clodius would probably be bearing some choice morsel of gossip, and curiosity got the better of him. He told Sositheus to show him in, and Clodius duly strolled into the library, his golden curls elegantly coiffed, his goatee trimmed, his bronzed limbs trailing a scent of crocus oil. He was thirty by now, a married man, having wed the fifteen-year-old heiress Fulvia in the summer, at the same time as he was elected a magistrate. Not that married life detained him much. Her dowry had bought them a large house on the Palatine, and there she sat alone most evenings while he continued with his roistering ways in the taverns of Subura.

'Tasty news,' announced Clodius. He held up a finger with a highly polished nail. 'But you mustn't tell a soul.'

Cicero gestured to him to take a seat. 'You know how discreet I am.'

'You will simply adore this,' said Clodius, settling himself down. 'This will make your day.'

'I hope it lives up to its billing.'

'It will.' Clodius tugged at his little beard with glee. 'The Warden of Land and Sea is divorcing.'

Cicero had been lounging back in his chair with a half-smile on his face, his usual posture when gossiping with Clodius. But now he slowly straightened. 'Are you absolutely sure?'

'I just heard it from your next-door neighbour, my darling sister – who sends her love, by the way – who received the news by special messenger from husband Celer last night. Apparently Pompey has written to Mucia telling her not to be in the house by the time he gets back to Rome.'

'Which will be when?'

'In a few weeks. His fleet is off Brundisium. He may even have landed by now.'

Cicero let out a low whistle. 'So he's coming home at last. After six years I was beginning to think I'd never see him again.'

'Hoping you'd never see him again, more like.'

It was an impertinent remark, but Cicero was too preoccupied with Pompey's impending return to notice. 'If he's divorcing, that must mean he's remarrying. Does Clodia know who he has in mind?'

'No, only that Mucia's out on her pretty little pink ear and the children go with Pompey, even though he hardly knows them. Her brothers are both up in arms, as you can imagine. Celer swears he's been betrayed. Nepos swears it even more. Clodia naturally finds it very funny. But still, what an insult, eh, after all they've done for him – to have their sister publicly cast aside for adultery.'

'And was she an adulteress?'

' Was she an adulteress? ' Clodius gave a surprisingly high-pitched giggle. 'My dear Cicero, the bitch has been rolling around on her back waving her legs in the air ever since he left! Don't tell me you haven't had her? If so, you must be the only man in Rome who hasn't!'

'Are you drunk?' demanded Cicero. He leaned across and sniffed at Clodius, then wrinkled his nose. 'You are, damn you. I suggest you go away and sober up, and mind your manners in future.'

For a moment I thought Clodius might hit him. But then he smirked, and started wiggling his head from side to side derisively. 'Oh, I am a terrible man. A terrible, terrible man…'

He looked so comical that Cicero forgot his anger and started laughing at him. 'Go on,' he said. 'Clear off, and take your mischief somewhere else.'

That was Clodius before he changed: a moody boy – a moody, spoilt, charming boy. 'That fellow amuses me,' Cicero remarked after the young patrician had gone, 'but I can't say I really care for him. Still,' he added, 'I'll forgive any man a coarse remark who brings me such intriguing news.' From then on he was too preoccupied trying to work out all the implications of Pompey's homecoming and potential remarriage to resume dictating his poem. I was grateful to Clodius for that at least, and thought no more about his visit for the remainder of the day.

A few hours later, Terentia came into the library to say goodbye to her husband. She was leaving to celebrate the Good Goddess's nocturnal rites. She would not be back until the morning. Relations between her and Cicero were cool. Despite the elegance of her private apartments on the upper floor, she still hated the house, especially the late-night comings and goings of Clodia's louche salon next door, and the proximity of the noisy crowds in the forum who gaped up at her whenever she went on to the terrace with her maids. To try to placate her, Cicero was going out of his way to be friendly.

'And where is the Good Goddess to be worshipped tonight? If,' he added with a smile, 'a mere man can be entrusted with such sacred information?' (The ritual was always held in the house of a senior magistrate, whose wife was responsible for organising it; they took it in turns.)

'At Caesar's house.'

'Aurelia presiding?'

'Pompeia.'

'I wonder if Mucia will be there.'

'I expect so. Why shouldn't she be?'

'She might be too ashamed to show her face.'

'Why?'

'It seems Pompey is divorcing her.'

'No?' Despite herself, Terentia was unable to conceal her interest. 'Where did you hear that?'

'Clodius came round to tell me.'

Immediately her lips compressed into a firm line of disapproval. 'Then it probably isn't true. You really ought to keep better company.'

'I shall keep what company I like.'

'No doubt, but do you really have to inflict it on the rest of us? It's bad enough living so close to the sister, without having the brother under our roof as well.'

She turned without saying goodbye and stalked off across the marble floor. Cicero pulled a face at her narrow back. 'First the old house was too far away from everyone, now the new one is too close. You're lucky you're not married, Tiro.'

I was tempted to reply that I had been given little choice in the matter.

He had been invited weeks ago to dine that evening with Atticus. Quintus had also been asked, and so, curiously enough, had I: our host's plan was that the four of us should reassemble in exactly the same place and at exactly the same time as last year, and drink a toast in celebration of the fact that we, and Rome, had survived. Cicero and I turned up at his house as darkness fell. Quintus was already there. But although the food and the wine were good enough, and there was Pompey to gossip about, and the library was conducive to conversation, the occasion was not a success. Everyone seemed out of sorts. Cicero had been put into a bad mood by his encounter with Terentia and was perturbed at the thought of Pompey's return. Quintus, coming to the end of his term as praetor, was heavily in debt and apprehensive about what province he might draw in the forthcoming lottery. Even Atticus, whose Epicurean sensibilities were normally unruffled by the outside world, was preoccupied with something. As usual, I took my mood from theirs, and only spoke when asked a question. We drank to the glorious fourth of December, but for once not even Cicero could bring himself to reminisce. Suddenly it did not seem appropriate to celebrate the deaths of five men, however villainous. The past fell like a clammy shadow across us, chilling all conversation. Finally Atticus said, 'I'm thinking of going back to Epirus.'

For a moment or two nobody spoke.

'When?' asked Cicero quietly.

'Directly after Saturnalia.'

'You're not thinking of going,' said Quintus with a nasty edge to his voice, 'you've already made up your mind. You're telling us.'

Cicero said, 'Why do you want to go now?'

Atticus played around with the stem of his glass. 'I came back to Rome two years ago to help you win the election. I've stayed ever since to support you. But now things seem to have settled down, I don't think you need me any more.'

'I most certainly do,' insisted Cicero.

'Besides, I have business interests over there I have to attend to.'

'Ah,' said Quintus into his glass, ' business interests. Now we get to the bottom of it.'

'What do you mean by that?' asked Atticus.

'Nothing.'

'No, please – say what's on your mind.'

'Leave it, Quintus,' warned Cicero.

'Only this,' said Quintus. 'That somehow Marcus and I seem to run all the dangers of public life, and shoulder all the hard work, while you are free to flit between your estates and attend to your business interests at will. You prosper through your connection with us, yet we seem permanently short of money. That's all.'

'But you enjoy the rewards of a public career. You have fame and power and will be remembered by history, whereas I am a nobody.'

'A nobody! A nobody who knows everybody!' Quintus took another drink. 'I don't suppose there's any chance of you taking your sister back with you to Epirus, is there?'

'Quintus!' cried Cicero. 'If your marriage is unhappy,' said Atticus mildly, 'then I am sorry for you. But that is hardly my fault.'

'And there we are again,' said Quintus. 'You've even managed to avoid marriage. I swear this fellow has the secret of life! Why don't you bear your share of domestic suffering like the rest of us?'

'That's enough,' said Cicero, getting to his feet. 'We should leave you, Atticus, before any more words are uttered that aren't really meant. Quintus?' He held out his hand to his brother, who scowled and looked away. 'Quintus!' he repeated angrily, and thrust out his hand again. Quintus turned reluctantly and glanced up at him, and just for an instant I saw such a flash of hatred in his eyes it made me catch my breath. But then he threw aside his napkin and stood. He swayed a little and almost fell back on to the table, but I grabbed his arm and he recovered his balance. He lurched out of the library and we followed him into the atrium.

Cicero had ordered a litter to take us home, but now he insisted that Quintus have it. 'You ride home, brother. We shall walk.' We helped him into the chair, and Cicero told the bearers to carry him to our old house on the Esquiline, next to the Temple of Tellus, into which Quintus had moved when Cicero moved out. Quintus was asleep even before the litter set off. As we watched him go, I reflected that it was no easy matter being the younger brother of a genius, and that all the choices in Quintus's life – his career, his home, even his wife – had been made in accordance with the demands of his brilliant, ambitious sibling, who could always talk him into anything.

'He means no harm,' said Cicero to Atticus. 'He's worried about the future, that's all. Once the senate has decided which provinces are to be put into this year's ballot and he knows where he's going, he'll be happier.'

'I'm sure you're right. But I fear he believes at least some of what he says. I hope he doesn't speak for you as well.'

'My dearest friend, I am perfectly aware that our relationship has cost you far more than you have ever profited from it. We have simply chosen to tread different paths, that's all. I have sought public office while you have yearned for honourable independence, and who's to say which of us is right? But in every quality that really matters I put you second to no man, myself included. There now – are we clear?'

'We are clear.'

'And you will come and see me before you leave, and write to me often afterwards?'

'I shall.'

With that Cicero kissed him on the cheek and the two friends parted, Atticus retreating into his beautiful house with its books and treasures, while the former consul trudged down the hill towards the forum with his guards. On this question of the good life and how to lead it – purely theoretical in my own case, of course – my sympathies were all with Atticus. It seemed to me at the time – and still does now, only even more so – an act of madness for a man to pursue power when he could be sitting in the sunshine and reading a book. But then, even if I had been born into freedom, I know I would not have possessed that overweening force of ambition without which no city is created, no city destroyed.

As chance would have it, our route home took us past the scenes of all Cicero's triumphs, and he fell very quiet as we walked, no doubt pondering his conversation with Atticus. We passed the locked and deserted senate house, where he had made such memorable speeches; the curving wall of the rostra, surmounted by its multitude of heroic statues, from which he had addressed the Roman people in their thousands; and finally the Temple of Castor, where he had presented his case to the extortion court in the long legal battle against Verres that had launched his career. The great public buildings and monuments, so quiet and massive in the darkness, nevertheless seemed to me that night as sub stantial as air. We heard voices in the distance, and occasional scuffling noises closer by, but it was only rats in the heaps of rubbish.

We left the forum, and ahead of us were the myriad lights of the Palatine, tracing the shape of the hill – the yellow flickering of the torches and braziers on the terraces, the dim pinpricks of the candles and lamps in the windows amid the trees. Suddenly Cicero halted. 'Isn't that our house?' he asked, pointing to a long cluster of lights. I followed his outstretched arm and replied that I thought it was. 'But that's very odd,' he said. 'Most of the rooms seem to be lit. It looks as though Terentia is home.'

We set off quickly up the hill. 'If Terentia has left the ceremony early,' said Cicero breathlessly over his shoulder, 'it won't be of her own volition. Something must have happened.' He almost ran along the street towards the house and hammered on the door. Inside, we found Terentia standing in the atrium surrounded by a cluster of maids and womenfolk, who seemed to twitter and scatter like birds at Cicero's approach. Once again she was wearing a cloak fastened tightly at the throat to conceal her sacred robes. 'Terentia?' he demanded, advancing towards her. 'What's wrong? Are you all right?'

'I am well enough,' she replied, her voice cold and trembling with rage. 'It is Rome that is sick!'

That so much harm could flow from so farcical an episode will doubtless strike future generations as absurd. In truth, it seemed absurd at the time: fits of public morality generally do. But human life is bizarre and unpredictable. Some joker cracks an egg, and from it hatches tragedy.

The basic facts were simple. Terentia recounted them to Cicero that night, and the story was never seriously challenged. She had arrived at Caesar's residence to be greeted by Pompeia's maid, Abra – a girl of notoriously easy virtue, as befitted the character of her mistress, and of her master too, for that matter, although he of course was not on the premises at the time. Abra showed Terentia into the main part of the house, where Pompeia, the hostess for the evening, and the Vestal Virgins were already waiting, along with Caesar's mother, Aurelia. Within the hour, most of the senior wives of Rome were congregated in this spot and the ritual began. What exactly they were doing, Terentia would not say, only that most of the house was in darkness when suddenly they were interrupted by screams. They ran to discover the source and immediately came across one of Aurelia's freed-women having a fit of hysterics. Between sobs she cried out that there was an intruder in the house. She had approached what she thought was a female musician, only to discover that the girl was actually a man in disguise! It was at this point that Terentia realised that Pompeia had disappeared.

Aurelia at once took charge of the situation and ordered that all the holy things be covered and that the doors be locked and watched. Then she and some of the braver females, including Terentia, began a thorough search of the huge house. In due course, in Pompeia's bedroom, they found a veiled figure dressed in women's clothes, clutching a lyre and trying to hide behind a curtain. They chased him down the stairs and into the dining room, where he fell over a couch and his veil was snatched away. Nearly everyone recognised him. He had shaved off his small beard and had put on rouge, black eye make-up and lipstick, but that was hardly sufficent to disguise the well-known pretty-boy features of Publius Clodius Pulcher – 'Your friend Clodius,' as Terentia bitterly described him to Cicero.

Clodius, who was plainly drunk, realising he was discovered, then jumped on to the dining table, pulled up his gown, exposing himself to all the assembled company, including the Vestal Virgins, and finally, while his audience was shrieking and swooning, ran out of the room and managed to escape from the house via a kitchen window. Only now did Pompeia appear, with Abra, whereupon Aurelia accused her daughter-in-law and her maid of collusion in this sacrilege. Both denied it tearfully, but the senior Vestal Virgin announced that their protests did not matter: a desecration had occurred, the sacred rites would have to be abandoned, and the devotees must all disperse to their homes at once.

Such was Terentia's story, and Cicero listened to it with a mixture of incredulity, disgust and painfully suppressed amusement. Obviously he would have to take a stern moral line in public and in front of Terentia – it was shocking, he agreed with her absolutely – but secretly he also thought it one of the funniest things he had ever heard. In particular, the image of Clodius waving his private parts in the horrified faces of Rome's stuffiest matrons made him laugh until his eyes watered. But that was for the seclusion of his library. As far as the politics were concerned, he thought Clodius had finally shown himself to be an irredeem able idiot – 'he's thirty, in the name of heaven, not thirteen' – and that his career as a magistrate was finished before it had even started. He also suspected, gleefully, that Caesar might be in trouble as well: the scandal had happened in his house, it had involved his wife; it would not look good.

This was the spirit in which Cicero went down to the senate the following morning, one year to the day after the debate on the fate of the conspirators. Many of the senior members had heard from their wives what had happened, and as they stood around in the senaculum waiting for the auspices to be taken, there was only one topic of discussion, or at least there was by the time Cicero had finished his rounds. The Father of the Nation moved solemnly from group to group, wearing an expression of piety and grave seriousness, his arms folded inside his toga, shaking his head and reluctantly spreading the news of the outrage to those who had not already heard it. 'Oh look,' he would say in conclusion, with a glance across the senaculum, 'there's poor Caesar now – this must be a terrible embarrassment for him.'

And Caesar did indeed look grey and grim, the young chief priest, standing alone on that bleak day in December, at the absolute nadir of his fortunes. His praetorship, now drawing to its close, had not been a success: at one point he was actually suspended, and had been lucky not to be hauled into court along with Catilina's other supporters. He was anxiously waiting to hear which province he would be allotted: it would need to be lucrative, as he was greatly in debt to the moneylenders. And now this ludicrous affair involving Clodius and Pompeia threatened to turn him into a figure of ridicule. It was almost possible to feel sorry for him as he watched, with hawkish eyes, Cicero going around the senaculum, relaying the gossip. Rome's cuckolder-in-chief: a cuckold! A lesser man would have stayed away from the senate for the day, but that was never Caesar's style. When the auspices had been read, he walked into the chamber and sat on the praetors' bench, two places along from Quintus, while Cicero went over to join the other ex-consuls on the opposite side of the aisle.

The session had barely begun when the former praetor Cornificius, who regarded himself as a custodian of religious probity, jumped up on a point of order to demand an emergency debate on the 'shameful and immoral' events that were said to have occurred overnight at the official residence of the chief priest. Looking back, this could have been the end for Clodius right then and there. He was not yet even eligible to take his seat in the senate. But fortunately for him, the consul presiding in December was none other than his stepfather-in-law, Murena, and whatever his private feelings on the subject, he had no intention of adding to the family's embarrassment if he could avoid it.

'This is not a matter for the senate,' ruled Murena. 'If anything has happened, it is the responsibility of the religious authorities to investigate.'

This brought Cato to his feet, his eyes ablaze with excitement at the thought of such decadence. 'Then I propose that this house asks the College of Priests to conduct an inquiry,' he said, 'and report back to us as soon as possible.'

Murena had little choice except to put the motion to the vote, and it passed without discussion. Earlier, Cicero had told me he was not going to intervene ('I'll let Cato and the others make hay if they want to; I'm going to keep out of it; it's more dignified'). However, when it came to the point, he could not resist the opportunity. Rising gravely to his feet, he looked directly at Caesar. 'As the alleged outrage occurred under the chief priest's own roof, perhaps he could save us all the trouble of waiting for the outcome of an inquiry and tell us now whether or not an offence was committed.'

Caesar's face was so clenched that even from my old position by the door – to which I had been obliged to return now that Cicero was no longer consul – I could see the muscle twitching in his jaw as he got up to reply. 'The rites of the Good Goddess are not a matter for the chief priest, as he is not even allowed to be present at the time they are celebrated.' He sat down.

Cicero put on a puzzled expression and rose again. 'But surely the chief priest's own wife was presiding over the ceremony? He must have at least some knowledge of what occurred.' He lapsed back into his seat.

Caesar hesitated for a fraction, then got up and said calmly, 'That woman is no longer my wife.'

An excited whisper went around the chamber. Cicero got up again. Now he sounded genuinely puzzled. 'So we may take it, therefore, that an outrage did occur.'

'Not necessarily,' replied Caesar, and once again sat down.

Cicero stood. 'But if an outrage did not occur, then why is the chief priest divorcing his wife?'

'Because the wife of the chief priest must be above suspicion.'

There was a good deal of amusement at the coolness of this reply. Cicero did not rise again, but signalled to Murena that he no longer wished to pursue the matter. Afterwards, as we were walking home, he said to me, not without a hint of admiration, 'That was the most ruthless thing I ever saw in the senate. How long would you say Caesar and Pompeia have been married?'

'It must be six or seven years.'

'And yet I'm certain he only made up his mind to divorce her when I asked him that question. He realised it was the best way to get himself out of a tight corner. You have to hand it to him – most men wouldn't abandon their dog so casually.'

I thought sadly of the beautiful Pompeia and wondered if she was aware yet that her husband had just publicly ended their marriage. Knowing how swiftly Caesar liked to act, I suspected she would be out of his house by nightfall.

When we got home, Cicero went at once to his library to avoid running into Terentia, and lay down on a couch. 'I need to hear some pure Greek to wash away the dirt of politics,' he said. Sositheus, who normally read to him, was ill, so he asked if I would do the honours, and at his request I fetched a copy of Euripides from its compartment, and unrolled it beside the lamp. It was The Suppliant Women he asked to hear, I suppose because on that day the execution of the conspirators was uppermost in his mind, and he hoped that at least in yielding up the bodies of his enemies for an honourable burial he had played the part of Theseus. I had just got to his favourite lines – Rashness in a leader causes failure; the sailor of a ship is calm, wise at the proper time. Yes, and forethought: this too is bravery – when a slave came in and said that Clodius was in the atrium.

Cicero swore. 'Go and tell him to get out of my house. I can't be seen to have anything more to do with him.'

This was not a job I relished, but I laid aside Euripides and went out into the atrium. I had expected to find Clodius in a state of some distress. Instead he wore a rueful smile. 'Good day, Tiro. I thought I had better come and see my teacher straight away and get my punishment over and done with.'

'I'm afraid my master is not in.'

Clodius's smile faltered a little, because of course he guessed that I was lying. 'But I have worked the whole thing up for him into the most wonderful story. He simply has to hear it. No, this is ridiculous. I won't be sent away.'

He pushed past me and walked across the wide hall and into the library. I followed, wringing my hands. But to his surprise and mine the room was empty. There was a small door in the opposite corner for the slaves to come and go, and even as we looked, it closed gently. The Euripides lay where I had left it. 'Well,' said Clodius, sounding suddenly uneasy, 'make sure you tell him I called.'

'I certainly shall,' I replied.
