Our guide to understanding the details of the all-important first page from the Codex Boturini - the departure of the Mexica from Aztlan... The Codex is also known as the ‘Tira de la Peregrinación’. The island in a lake, Aztlan (‘Place of Herons’ or ‘Place of Whiteness’), mythical homeland of the Mexica, is shown on the left (North) (East is at the top). Under the temple a couple are shown; unusually, only the woman is identified - Chimalma(n) (‘Shield-hand’), mother of Quetzalcóatl and wife of Mixcóatl, and a key spirit accompanying the Aztecs on their long journey south... The Mexica are just one of a handful of tribes who leave Aztlan together in the year One-Flint (1168 CE) in search of a new homeland. Aztlan is connected in Aztec mythology with Colhuacan (‘Place of Ancestors’) - the cave mountain on the right, birthplace of Huitzilopochtli and of the Mexica nation. The tribes are being called to embark on their epic trek by the call (note the trail of speech marks) of a hummingbird, messenger of Huitzilopochtli.
