Ancient Aztec sculpture disc from the Templo Mayor, showing a goddess sliced and diced by her brother.

Some archaeologists believe that the decapitated and limbless body of sacrifice victims were tossed down the pyramid onto this disc.

Coyolxaqui, the Aztec moon goddess:

“The pregnancy of Coatlicue, the maternal Earth deity, made her other children embarrassed, including her oldest daughter Coyolxauhqui. As she swept the temple, a few hummingbird feathers fell into her chest. Coatlicue’s child, Huitzilopochtli, sprang from her womb in full war armor and killed Coyolxauhqui, along with their 400 brothers and sisters. He cut off her limbs, then tossed her head into the sky where it became the moon, so that his mother would be comforted in seeing her daughter in the sky every night.”
