The Dresden Codex (
Codex Dresdensis) is held in the
Sächsische Landesbibliothek (SLUB), the state library in
Dresden, Germany. It is the most elaborate of the codices, and also a highly important specimen of
Maya art. Many sections are ritualistic (including so-called 'almanacs'), others are of an
astrological nature (
eclipses, the
Venus cycles). The codex is written on a long sheet of paper that is 'screen-folded' to make a book of 39 leaves, written on both sides. It was probably written between the twelfth and fourteenth centuries. After it was taken to Europe and was bought by the royal library of the court of Saxony in Dresden in 1739. The only exact replica, including the
huun, made by a German artist is displayed at the
Museo Nacional de Arqueología in
Guatemala City, since October 2007. It is not clear who brought the Dresden Codex to Europe. It arrived sometime in the late 18thcentury, potentially from the first or second generation of Spanish conquistadores. Even though the last date entry in the book is from several centuries before its relocation, the book was likely used and added to until just before the conquerors took it. About 65 per cent of the pages in the Dresden Codex contain richly illustrated astronomical tables. These tables focus on eclipses, equinoxes and solstices, the sidereal cycle of Mars, and the synodic cycles of Mars and Venus. These observations allowed the Mayans to plan the calendar year, agriculture, and religious ceremonies around the stars. In the text, Mars is represented by a long nosed deer, and Venus is represented by a star. Pages 51–58 are eclipse tables. These tables accurately predicted solar eclipses for 33years in the 8thcentury, though the predictions of lunar eclipses were far less successful. Icons of serpents devouring the sun symbolize eclipses throughout the book. The glyphs show roughly 40 times in the text, making eclipses a major focus of the Dresden Codex. The first 52 pages of the Dresden Codex are about divination. The Mayan astronomers would use the codex for day keeping, but also determining the cause of sickness and other misfortunes. Though a wide variety of gods and goddesses appear in the Dresden Codex, the Moon Goddess is the only neutral figure. In the first 23 pages of the book, she is mentioned far more than any other god. Between 1880 and 1900, Dresden librarian
Ernst Förstemann succeeded in deciphering the
Maya numerals and the
Maya calendar and realized that the codex is an
ephemeris. Subsequent studies have decoded these astronomical almanacs, which include records of the cycles of the Sun and Moon, including eclipse tables, and all of the naked-eye planets. The "Serpent Series", pp. 61–69, is an
ephemeris of these phenomena that uses a base date of 1.18.1.8.0.16 in the prior era (5,482,096 days). ==Madrid Codex==
