"A Possible Solution of the Number Series on Pages 51 to 58 of the Dresden Codex" by Carl E. Guthe is an early 20th-century academic study that digs into a number pattern within the Dresden Codex, a rare Mayan book. It zooms in on a series of numbers covering 11,960 days, split into sections echoing the moon's phases, striving to unlock the secrets of how the lunar calendar connects with space events, particularly charting the moon's monthly cycles. Guthe figures out how these numbers link to lunar cycles, especially highlighting parts of 148, 177, and 178 days. The author points out some mix-ups and mistakes in the manuscript, suggesting they're mostly copying errors instead of planned oddities. As a result, this strengthens the idea that the series acts as an eclipse calendar mixed with the lunar schedule, enhancing our knowledge of how the Maya understood astronomy and used calendars that tied into nature's rhythms.
