The Undulating Serpent wall is a two-part monument flanking the steps leading up the main façade of the Templo Mayor in Tenochtitlan[i]. As Coyolxauhqui lies directly at the bottom of the stairs on the south side of the temple, her proximity to the serpent wall is significant. Serpents are associated with the earth, fertility, and, more specifically, Coyolxauhqui’s mother Coatlicue. Coyolxauhqui is depicted with many earth deity symbols, connecting her with the symbolism of the snake. Furthermore, Coyolxauhqui lies at the bottom of the symbolic Mt. Coatepec, the “Serpent Mountain,” the pathway to which is flanked by the serpent wall[ii].
