These documents, which are believed to be Postclassic copies of earlier Classic-period originals, contain significant information on these subjects:3

  • Dresden Codex: Renowned for its exceptional accuracy, this codex contains complex astronomical calculations, including tables for predicting eclipses and tracking the synodical period of Venus.1
  • Madrid Codex: This text provides a wealth of information concerning astrology and divinatory practices. It is particularly valuable for identifying various Maya deities and reconstructing rituals, such as those performed to usher in new years.4
  • Paris Codex: This fragmentary manuscript is devoted almost entirely to Maya ritual and ceremony, including rites held to celebrate the conclusion of 20-year periods.5
  • Grolier Codex: Like the others, this document is categorized among the surviving Indigenous books that deal with astronomical calculations, divination, and ritual.3
