Born in Austro-Hungary in either 1748 or 1750, Guillermo Dupaix became one of the first Europeans to observe and describe the archaeological riches of Chiapas, Oaxaca, and Yucatan. Between 1805 and 1807, he lead three Royal expeditions to survey major Mexican archaeological sites, working in close concert with Jose Luciano Castañeda, an artist with the National Museum. Among the sites they visited were the Mayan ruins at Palenque, the Zapotec/Mixtec site at Mitla, and several Aztec sites. The APS version of Viages Sobre las Antiquedades Mejicanas is one of several contemporary manuscript copies of Dupaix's seminal work on Mexican archaeology. The work consists of two volumes, the first containing the text, the second, copies of Castañeda's illustrations, which here lack the distortions introduced in King's edition.
