In 1644 Don Fernando de la Carrera, the Cura of Reque, near Chiclayo, published his grammar of the Yunca language, at Lima. This is the language which was once spoken in the valleys of the Peruvian coast by the civilized people whose ruler was the grand Chimu. Now the language is extinct, or spoken only by a few Indians in the coast village of Eten. The work of Carrera is therefore important, as, with the exception of a specimen of the language preserved by Bishop Oré, it is the only book in which the student can now obtain any linguistic knowledge of the lost civilization. The Yunca grammar was reprinted in numbers in the _Revista de Lima_ of 1880 and following years.[1319] There was a professorial chair for the study of Quichua in the University of San Márcos at Lima, and the language was cultivated, during the two centuries after the conquest, as well by educated natives as by many Spanish ecclesiastics. The sermons of Dr. Don Fernando de Avendaño have already been referred to.[1320] Dr. Lunarejo, of Cuzco, was another famous Quichuan preacher, and the _Confesionarios_ and catechisms in the language were very numerous. Bishop Louis Geronimo Oré, of Guamanga, in his ritualistic manual, gives the Lord’s prayer and commandments, not only in Quichua and Aymara, but also in the Puquina language spoken by the Urus on Lake Titicaca, and in the Yunca language of the coast, which he calls Mochica.[1321] A very curious book was published at Lima in 1602, which, among other things, treats of the Quichua language and of the derivations of names of places. The author, Don Diego D’Avalos y Figueroa, appears to have been a native of La Paz. He was possessed of sprightly wit, was well read, and a close observer of nature. We gather from his _Miscelanea Austral_[1322] the names of birds and animals, and of fishes in Lake Titicaca, as well as the opinions of the author on the cause of the absence of rain on the Peruvian coast, on the lacustrine system of the Collao, and on other interesting points of physical geography.[1323] In modern times the language of the Incas has received attention from students of Peruvian history. The joint authors, Dr. Von Tschudi and Don Mariano Eduardo de Rivero, in their work entitled _Antigüedades Peruanas_, published at Vienna in 1851, devote a chapter to the Quichua language. Two years afterwards Dr. Von Tschudi published a Quichua grammar and dictionary, with the text of the Inca drama of Ollantay, and other specimens of the language.[1324] The present writer’s contributions towards a grammar and dictionary of Quichua were published by Trübner in 1864, and a few years previously a more complete and elaborate work had seen the light at Sucre, the capital of Bolivia. This was the grammar and dictionary by Father Honorio Mossi, of Potosi, a large volume containing thorough and excellent work.[1325] Lastly a Quichua grammar by José Dionisio Anchorena was published at Lima in 1874.[1326]
