Knox poured more tea for Kostas and himself, watched his sugar dissolve in the whirlpool of his stirring. 'What about the Therapeutae?' he asked. 'Did they have any links to these Carpocratians?'
Kostas pulled a face. 'I've heard it claimed that Carpocrates was a devotee of the teachings of a Talmudic figure called Jehoshua Ben Panther. A fascinating character. You may have heard of him, because he's been conflated with Christ by some, but he was most probably an Essene leader.'
'Linking him to the Therapeutae.'
'Quite,' nodded Kostas. 'And their doctrines mesh too, though admittedly with one major discrepancy. The Therapeutae were famously chaste, you see, whereas the Carpocratians were notorious for licentiousness and orgies. But almost everything we know about the Carpocratians was written by their enemies, so it's quite possible that that was nothing but malicious propaganda. And if you discount it, the two groups prove a remarkable fit.'
'In what way?'
'In every way. Long initiations. Water baptisms. The rejection of materialism. Carpocrates is credited with the phrase "Property is Theft", you know. Both abhorred slavery. Both believed in some kind of afterlife or reincarnation. Both accorded unusual respect and power to women. One of Carpocrates' most celebrated followers, Marcellina, even became quite a figure in Rome. They both had very Hellenic elements, and shared a great deal with Pytha-goreanism. Both included traces of sun-worship. Both studied angels and demons. Both believed in and practised magic. Both prized numbers and symbols. And both were hideously persecuted too. Maybe that's why they both lived outside Alexandria. And, now that I think about it, the Carpocratians appeared around AD one hundred and twenty, around the same time we lose track of the Therapeutae.'
'You're suggesting the Therapeutae became the Carpocratians?'
'It's not inconceivable, I suppose. But all I'm really saying is that it's quite possible they overlapped in some way. Bear in mind that this whole region was fervid with philosophical and religious energy back then – everyone borrowing, sharing, arguing. Religions hadn't yet set in the way they have today. Places that were sacred to one were holy to others too. Many early churches were built on old pagan temples, you know. Even the Vatican. So perhaps they lived together for a while, or perhaps the Carpocratians took over this antiquity of yours after the Therapeutae moved on.'
Knox nodded. It seemed plausible enough, though plausibility was a very different beast from truth. 'What else do we know about the Carpocratians?'
'Founded in Alexandria, like I say, but they flourished elsewhere too. In Rome, as I mentioned. And I believe they also had a temple in…' He pushed himself to his feet, went over to his shelves, plucked down a volume, leafed through it, then put it back, shaking his head.
'Come on, Kostas. Just tell me.'
'Patience, young man. Patience.' He pulled out a weighty church encyclopaedia from his shelves, hefted it over to the corner table, licked his thumb and forefinger to turn the thin leaves until he found the page. 'Yes,' he said. 'They had a temple on one of the Greek islands.'
Knox frowned as he recalled his recent phone call with Augustin. 'Not Cephallonia, I don't suppose?'
Kostas smiled quizzically. 'How on earth did you know that?'
'What else does it say?'
He licked his fingertips, turned the page. 'Ha! How about that!'
'How about what?'
'Oh, yes. Oh, you'll like this.'
'Come on, Kostas. Just tell me, will you?'
'You know how Christian groups identified each other with secret signs and markings like the fish and the cross? Well, the Carpocratians had one of their own.'
'What?'
'It doesn't say,' said Kostas. 'All it says is where on their bodies it was tattooed.'
'And?'
Kostas's eyes twinkled. 'It was on the back of their right earlobes,' he said.
