Image: Dresden Codex - Plate 34
The Dresden Codex, written about 1000-1200 CE, is a copy of another text that was written about 600-900 CE by the Maya culture. It was possibly sent by Hernán Cortés to King Charles I of Spain in 1519. It was purchased by Johann Christian Götze from a private owner in 1739 for the Royal Library of Dresden (now the Sächsische Landesbibliothek), traced and colored by Agostino Aglio in 1825-1826, and published by Lord Kingborough in 1830-1831.
