A Study of the Manuscript Troano is Cyrus Thomas’s paper for the U. S. Geographical and Geological Survey of the Rocky Mountain Region, J. W. Powell in charge, with an introduction by D. G. Brinton. Washington, Government Printing Office, 1882. The manuscript was found about 1866 at Madrid by the Abbe Brasseur de Bourbourg, and named for Don Juan de Tro y Ortolano. It is a maguey strip about 14 feet (4.27 meters) by 9 inches, thirty-five folds, seventy painted pages. Thomas reads it as a priests’ ritual calendar running through a grand cycle of 312 years, the Ahau or Katun a period of 24 years, the series beginning with a Cauac year. He puts the people in the interior, away from the sea, in Peten, and he dates the writing to the middle or latter half of the fourteenth century, before the fall of Mayapan. Maize was dibbled five grains to a hill. The study does not discuss Atlantis.
