Sacrifice
Sacrifices made in return for divine favour were numerous: animals, birds, insects, fish, agricultural products, flowers, rubber, jade, and blood drawn from the tongue, ears, arms, legs, and genitals. Evidence of human sacrifice in Classic times includes two Piedras Negras stelae, an incised drawing at Tikal, the murals at Bonampak, various painted ceramic vessels, and some scenes in native manuscripts. Only in the Postclassic era did this practice become as frequent as in central Mexico. Toltec-Maya art shows many instances of human sacrifice: removal of the heart, arrow shooting, or beheading. At Chichén Itzá, in order to obtain rain, victims were hurled into a deep natural well (cenote) together with copper, gold, and jade offerings. Prayers for material benefits (which were usually recited in a squatting or standing position), fasting and continence (often for 260 days), and the drawing of blood from one’s body often preceded important ceremonies and sacrifices.
These practices had become so deeply rooted that, even after the Spanish conquest, Christian-pagan ceremonies occasionally took place in which humans were sacrificed by heart removal or crucifixion. The last recorded case occurred in 1868 among the Chamula of Chiapas.
