1430

1430 was the year Barbara Wright estimated that a corpse she and Susan once found just outside the TARDIS had died. She did so based upon her knowledge of the Aztec Empire, which allowed her to identify the trinkets alongside the body as coming from what she called the Aztecs' "early period". Barbara quickly understood that the remains were those of Yetaxa, a figure of god-like importance to the Aztecs. (TV: The Aztecs; PROSE: The Aztecs)
