[3] Fernando Montesinos, an ecclesiastical lawyer of the seventeenth century, appears to have gone to Peru in 1629 as the follower of that well-known viceroy, the Count of Chinchon, whose wife having contracted malaria was cured by the use of Peruvian bark or quinine and was instrumental in the introduction of this medicine into Europe, a fact which has been commemorated in the botanical name of the genus cinchona. Montesinos was well educated and appears to have given himself over entirely to historical research. He traveled extensively in Peru and wrote several books. His history of the Incas was spoiled by the introduction, in which, as might have been expected of an orthodox lawyer, he contended that Peru was peopled under the leadership of Ophir, the great-grandson of Noah! Nevertheless, one finds his work to be of great value and the late Sir Clements Markham, foremost of English students of Peruvian archeology, was inclined to place considerable credence in his statements. His account of pre-Hispanic Peru has recently been edited for the Hakluyt Society by Mr. Philip A. Means of Harvard University. [4] Another version of this event is that the quarrel was over a game of chess between the Inca and Diego Mendez, another of the refugees, who lost his temper and called the Inca a dog. Angered at the tone and language of his guest, the Inca gave him a blow with his fist. Diego Mendez thereupon drew a dagger and killed him. A totally different account from the one obtained by Garcilasso from his informants is that in a volume purporting to have been dictated to Friar Marcos by Manco's son, Titu Cusi, twenty years after the event. I quote from Sir Clements Markham's translation:
