=II.= THE QUICHUA LANGUAGE AND LITERATURE.—No real progress can be made in the work of elucidating the ancient history of Peru, and in unravelling the interesting but still unsolved questions relating to the origin and development of Inca civilization, without a knowledge of the native language. The subject has accordingly received the close attention of laborious students from a very early period, and the present essay would be incomplete without appending an enumeration of the Quichua grammars and vocabularies, and of works relating to Inca literature. Fray Domingo de San Tomas, a Dominican monk, was the first author who composed a grammar and vocabulary of the language of the Incas. He gave it the name of Quichua, probably because he had studied with members of that tribe, who were of pure Inca race, and whose territory lies to the westward of Cuzco. The name has since been generally adopted for the language of the Peruvian empire.[1311] Diego de Torres Rubio was born in 1547, in a village near Toledo, became a Jesuit at the age of nineteen, and went out to Peru in 1577. He studied the native languages with great diligence, and composed grammars and vocabularies. His grammar and vocabulary of Quichua first appeared at Saville in 1603, and passed through four editions.[1312] A long residence in Chuquisaca enabled him to acquire the Aymara language, and in 1616 he published a short grammar and vocabulary of Aymara. In 1627 he also published a grammar of the Guarani language. Torres Rubio was rector of the college at Potosi for a short time, but his principal labors were connected with missionary work at Chuquisaca. He died in that city at the great age of ninety-one, on the 13th of April, 1638. Juan de Figueredo, whose Chinchaysuyu vocabulary is bound up with later editions of Torres Rubio, was born at Huancavelica in 1648, of Spanish parents, and after a long and useful missionary life he died at Lima in 1724.
