Codex Ixtlilxochitl

The Codex Ixtlilxochitl is an early 17th century fragment detailing, among other subjects, a calendar of the annual festivals and rituals celebrated at the Aztec teocalli ("pyramids") during the Mexican calendar year. Each of the 18 months is represented by a god or an historical character. Written in Spanish, the Codex Ixtlilxochitl has 50 pages comprising 27 separate sheets of European paper with 29 illustrations. It was derived from the same source as the Codex Magliabechiano. It was named after Fernando de Alva Cortés Ixtlilxochitl (between 1568 & 1578 – c. 1650), the author of Obras Historicas and a member of the ruling family of Texcoco, and is held in the Bibliothèque Nationale in Paris. The manuscript consists of four different sections, all written out and illustrated on European paper, of which at least the first section is fragmentary. Sections 1–3 have been reproduced in the original colors, section 4 is in b/w.
