Where is this late post-classic Mexica sculpture, which Antonio de León y Gama wrote an essay about at the time the sculpture was discovered, housed?
Antonio de León y Gama Antonio de León y Gama (1735–1802) was a Mexican astronomer, anthropologist and writer. When in 1790 the Aztec calendar stone (also called sun stone) was discovered buried under the main square of Mexico City, he published an essay about it, "Descripción histórica y cronológica de las dos piedras que con ocasión del nuevo empedrado que se está formando en la plaza principal de México, se hallaron en ella el año de 1790" ("Historical and chronological description of two Stones that were found in the plaza of Mexico in 1790 upon the occasion of laying the new pavement") explaining the functioning of aztec calendars.
Codex of Santa Catarina Ixtepeji The Codex of Santa Catarina Ixtepeji (in Spanish, Códice de Santa Catarina Ixtepeji) is a late 17th-early 18th century bilingual codex in the Spanish and Zapotec languages. It is a 7 ft , a hand-painted history and map recounting part of the history of Santa Catarina Ixtepeji, in the Ixtlán District in the Sierra Norte region of Oaxaca in southwestern Mexico. It had been held in the hands of private collectors into the 20th century, and was re-discovered and identified as part of the holdings of the American Geographical Society Library at the University of Wisconsin–Milwaukee in early 2012, as the result of efforts of scholars at UWM, Marquette University and the Universidad Nacional Autónoma de México.
