Historical and chronological description of two Stones that were found in the plaza of Mexico upon the occasion of laying the new pavement

This book was published in 1792. In it León y Gama described the discovery in 1790 of two of the most important pieces of Aztec art in the Zócalo, main plaza of the city of Mexico: the sun stone and a statue of Coatlicue, an Aztec goddess. León y Gama also included in it most of his knowledge and theories on how the Aztecs measured time. The work, as opposed to authors of previous centuries, praised Aztec society and their scientific and artistics achievements in line with the growing Mexican nationalism in the late 18th century. It was published by Felipe de Zúñiga y Ontiveros, owner of one of the most important printing establishments in America at the time. In addition to print the book had three folded manuscript watercolor drawings. Thanks to the publication of the book León y Gama is considered by many the first Mexican archeologist.^[5]
