Statues of Tlatoque (Nahuatl for Aztec rulers) Ahuitzotl and Itzcoatl are installed in Mexico City. They are collectively known as the Monumento a los Indios Verdes (lit. transl. "Monument to the Green Indians"). The statues are verdigris due to the effects of weather. They are around 3 meters (9.8 ft) to 4 meters (13 ft) tall and their plinths have inscriptions in Nahuatl. The statues were created by Alejandro Casarín to represent Mexico at the 1889 Paris Exposition.
