Codex Borbonicus

The Codex Borbonicus is a single 46.5-foot (14.2 m) long sheet of amatl "paper". Although there were originally 40 accordion-folded pages, the first two and the last two pages are missing. It was originally pictorial and logographic as was usual for pre-Columbian Aztec codicies, although some Spanish descriptions have been added. There is dispute as to whether the Codex Borbonicus is pre-Columbian, as the calendar pictures all contain room above them for Spanish descriptions.
