Human sacrifice was a religious practice characteristic of pre-Columbian Aztec civilization, as well as of other mesoamerican civilizations such as the Maya and the Zapotec. The Aztecs had 18 months in one cycle, and for each of the 18 months there was ritual sacrifice. The victim would be painted as a part of the ritual, they would be placed on a slab where their heart would be removed and held up to the sun. The body would be thrown down the stairs of the temple, the limbs were removed and later cooked. It's estimated that 20,000 humans were sacrificed by the Aztecs every year.
