Pedro Sarmiento de Gamboa 
History of the Incas [EPUB ebook] 

According to Wikipedia: ‘Pedro Sarmiento de Gamboa (1532–1592) was a Galician (Spanish) explorer, author, historian, astronomer, and scientist… Written in Cuzco, the capital of the Inca Empire, just forty years after the arrival of the first Spaniards in the city, Sarmiento’s The History of the Incas contains extremely detailed descriptions of Inca history and mythology. The royal sponsorship of the work guaranteed Sarmiento direct access to the highest Spanish officials in Cuzco. It also allowed him to summon influential natives, as well as those who had witnessed the fall of the Inca Empire, so that they could relate their stories. Sarmiento traveled widely and interviewed numerous local leaders and lords, surviving members of the royal Inca families, and the few remaining Spanish conquistadors who still resided in Cuzco. Once the first draft of the history was completed, in an unprecedented effort to establish the unquestionable authenticity of the work, his manuscript was read, chapter by chapter, to forty-two indigenous authorities for their commentary and correction. After the public reading, which occurred on 29 February and 1 March 1572, the manuscript was entrusted to a member of the viceroy’s personal guard. He was to take the manuscript to Spain and deliver it to King Philip II, along with four painted cloths showing the history of the Incas and a number of other artifacts and objects that Toledo had collected. However, due to a series of unusual events, this irreplaceable document of Inca history was relegated to obscurity for centuries.’
