The
Codex Telleriano-Remensis is divided into three sections. The first section, spanning the first seven pages, describes the 365-day solar calendar, called the
xiuhpohualli. The second section, spanning pages 8 to 24, is a
tonalamatl, describing the 260-day
tonalpohualli calendar. The third section is a history, itself divided into two sections which differ stylistically. Pages 25 to 28 are an account of
migrations during the 12th and 13th centuries, while the remaining pages of the codex record historical events, such as the ascensions and deaths of rulers, battles,
earthquakes, and
eclipses, from the 14th century to the 16th century, including events of early
Colonial Mexico. The codex contains twelve references to a series of earthquakes that occurred between 1460 and 1542. This was found by Gerardo Suárez and Virginia García-Acosta to be the earliest references to seismic activity in the Americas. Suárez commented that the find was not surprising since earthquakes were both frequent in the area and important to
Mesoamerican cosmology. ==Publication==
