The codex was written by eight different scribes, each with their own distinctive style, type of glyphs
and subject matter. It is linked to the Yucatecan Maya in Chichén Itzá, the extraordinary ancient
Maya city situated in the north of the Yucatán Peninsula. It was made between A.D. 1200-1250,
and was still possible in use when the conquistadors arrived. The "Codex Dresdensis" as one of the
few pre-Columbian Mayan hieroglyphic writings (most of them on stelas found in Palenque, one of
the ancient cities of Yucatán) contains astronomical calculations of exceptional accuracy.

There are almanacs and day counts for worship and prophecies; two astronomical and astrological tables, one dealing with eclipses and the
other Venus and katún (a 20-year period) prophecies. It contains references and predictions for time and agriculture, favorable days for pre-
dictions, as well as texts about sickness, medicine, and seemingly, conjunctions of constellations, planets and the Moon. It also contains a page
about a flood, a prophecy or maybe a reference to the rainy seasons so vital to the Maya.

The text has auguries that helped priests make predictions. It is devided into 11 sections: the first includes rit-
uals for the gods Kukulcán and Itzamn : the second refers to bad omens concerning crops and offerings that
should be made to regularize rain; the third is devoted to a katn of 52 ritual years; and the final eight parts refer
to hunting, calendars, death and purification, among other themes.
