This is only one of the many beautiful images of Codex Fejérváry-Mayer posted by peacay @ Bibliodyssey. Oh Mind! I just love the shapes and colours.
Codex Fejérváry-Mayer is a 15th or early 16th century Aztec (or Mixtec) manuscript on deer skin from Veracruz in central Mexico. Named for a Hungarian collector and British patron, this pre-Columbian accordion-style document outlines the cosmological and calendrical orientations of the Mayan people. As a typical calendar codex tonalamatl dealing with the sacred Aztec calendar -- the tonalpohualli -- it is grouped in the Codex Borgia group.
