Copil (son of Malinalxochitl)

In Aztec mythology, Copil was the son of the goddess Malinalxochitl and Malinalco king, Chimalcuauhtli.^[1]

When grown he sought revenge for his mother's abandonment by her brother, Huītzilōpōchtli. When the Mexica were encamped at Chapultepec, he confronted his uncle. Hostility brewed, and Copil was killed^[1] on the hill Peñón de los Baños [es] by Mexicas under orders of Huītzilōpōchtli,^[2] while Copil was awaiting to watch the battle between the Mexicas and tribes he incited to fight them.^[3] He was slain by priest Cuauhtlequetzqui, who later married Copil's daughter, Xicomoyahual.^[4] He was decapitated and his head was placed atop the hill and then an outcrop in Lake Texcoco.^[5] His heart was extracted and thrown into the swamp where it grew into nopal. It was here the Mexicas were given the signal to build Tenochtitlan.^[3][5]
