Note 8 — Chapter XV · WHO WERE THE MAYANS?
Reading edition
The value of the Tula tradition is best gauged by a comparison of the dates given by authorities. Thus Sahagun (Historia de la Nueva España) places its destruction in 319 B.C.; Ixtlilxochitl (Historia Chichemeca, iii. cap. 4) brings it down to 969 A.D.; the Codex Ramirez gives it as 1168 A.D.; and so on. There is an equally amazing variation about the date of its founding.
