The Spanish and Portuguese missionaries in America, too, (especially those of the Jesuit order) rendered good service to the study of the numerous native languages of both continents.[85] Most of the modern learning on the subject is derived from their treatises, chiefly manuscript, preserved by the Society. Nor were the other orders less efficient. Padre Josef Carabantes, a Capuchin of the province of Aragon, (born in 1648) wrote a most valuable practical treatise for the use of missionaries, which was long a text book in their hands. One of the Portuguese missionaries in Abyssinia, Father Pedro Paez, who succeeded Fernandez, and whose memory still lingers among the native traditions of the people,[86] not only became thorough master of the popular dialects of the various races of the Valley of the Nile, but attained a proficiency in Gheez, the learned language of Abyssinia, not equalled even by the natives themselves.[87] A Franciscan missionary at Constantinople about the same time, mentioned by Cyril Lucaris, is described by him as “acquainted with many languages;”[88] but I have not been able to discover his name. By far the most eminent linguist of the Peninsula, however, is the learned Jesuit, Father Lorenzo Hervas-y-Pandura. He was born in 1735, of a noble family, at Horcajo, in la Mancha. Having entered the Jesuit society, he taught philosophy for some years in Madrid, and afterwards in a convent in Murcia; but at length, happily for the interests of science as well as of religion, he embraced a missionary career, and remained attached to the Jesuit mission of America, until 1767. On the suppression of the order, Father Hervas settled at Cesena, and devoted himself to his early philosophical studies, which, however, he ultimately, in a great measure, relinquished in order to apply himself to literature and especially to philology. When the members of the society were permitted to re-establish themselves in Spain, Hervas went to Catalonia; but he was obliged to return to Italy, and settled at Rome, where he was named by Pius VII. keeper of the Vatican Library. In this honourable charge he remained till his death in 1809.
