Aztl獺n is the legendary ancestral home of the Nahua peoples. The mythical homeland of the Aztecs. Aztec is the Nahuatl word for "people from Aztlan". The role of Aztl獺n is slightly less important to Aztec legendary histories than the migration to Tenochtitl獺n itself. The Boturini Codex was painted by an unknown Aztec author some time between 1530 and 1541, roughly a decade after the Spanish conquest of Mexico. Pictorial in nature, it tells the story of the legendary Aztec journey from Aztl獺n to the Valley of Mexico. Rather than employing separate pages, the author used one long sheet of amatl, or fig bark, accordion-folded into 21? pages. The drawings are not colored, but rather merely outlined with black ink.
