Polo de Ondegardo, Report on the government of the Yncas (Peru, c. 1560s; first printed in English, London 1873)

A corregidor of Cuzco who studied Inca law in order to govern by it, and whose working notes survive as a report that dates the empire from quipu king-lists, measures the courier relay in leagues and days, refuses informants who put the origin before the flood, and tells his own government that the wise legislation of the Yncas ought to be used and imitated. The same notes record the levy of girls that legislation also enforced.
