LEON, Peter Cicca de, author of the history of Peru. He left Spain, his native country, at 13 years of age in order to go into America, where he resided 17 years; and observed so many remarkable things, that he resolved to commit them to writing. The first part of his history was printed at Seville in 1553. He began it in 1541, and ended it in 1550. He was at Lima, the capital of the kingdom of Peru, when he gave the finishing stroke to it, and was then 32 years of age.
