Note 28 — II. The Mathematical Elements.

Professor Cyrus Thomas, in his carefully written article, “The Maya Year,” in the Bulletins of the Bureau of Ethnology (Washington, 1894), has collected evidence that the same calendar system, based, he believes, on the year of 365 days, was used in Palenque, Menche (Lorillard City), and Tikal, as well as in the Cod. Dresdensis. That the Mayas had, at the time of the Conquest, long known the year of 365 days, was demonstrated from the Codices by Dr. Förstemann. (See his Erläuterungen zur Maya-Handschrift, Dresden, 1886, p. 21, and his “Die Zeitperioden der Mayas,” in Globus, January, 1892).
