A basalt disc about 3.6 metres across, carved in the Mexica capital Tenochtitlan during the reign of Moctezuma II. A central face, often identified as the sun god Tonatiuh, is framed by the four earlier eras of creation and a ring of twenty day signs. Buried after the Spanish conquest, it was dug up in Mexico City's main square in 1790.

The central figure clutches a human heart in each clawed hand, and his tongue is a stone sacrificial knife. Moctezuma II's name glyph is carved nearby.
