The commercial enterprise of the Western Nations, and especially of the Venetians and Genoese, was a still more powerful instrument of the interchange of languages. Few modern voyagers have possessed more of that spirit of travel which is the best aid towards the acquisition of foreign tongues, than the celebrated Marco Polo. It is hard to suppose that he can have returned from his extensive wanderings in Persia, in Tartary, in the Indian Archipelago, and in China and Tibet, without some tincture of their languages. Still less can this be supposed of his countryman, Josaphat Barbaro, who sojourned for sixteen years among the Tartar tribes.[31] It was in the commercial settlements of the Venetians in the Levant that the profession of interpreters, of which I shall have to speak hereafter, and which has since become hereditary in certain families, was originated or brought to perfection.[32] * * * * * It is only, however, from the revival of letters, properly so called, that the history of linguistic studies can be truly said to commence. The attention of Scholars, in the first instance, was chiefly directed towards the classical languages and the languages of the Bible. The Greek scholars who were driven to the West by the Moslem occupation of Constantinople brought their language, in its best and most attractive form, to the Universities of Italy. In the Council of Florence, in 1438, more than one Italian divine, especially Ambrogio Traversari, was found capable of holding discussions with the Greek representatives in their native tongue. In like manner, the Jews and Moors, who were exiled from Spain by the harsh and impolitic measures of Ferdinand and Isabella, deposited through all the schools of Europe the seeds of a solid and critical knowledge of Hebrew and Arabic and their cognate languages. The fruits of their teaching may be discerned at a comparatively early period in the biblical studies of the time. Antonio de Lebrixa published, in 1481, a grammar of the Latin, Castilian and Hebrew languages: and I need only allude to the mature and various oriental learning which Cardinal Ximenes found ready to his hand, in the very first years of the sixteenth century, for the compilation of the Complutensian Polyglot. Although some of the scholars whom he engaged, as for instance, Demetrius Ducas, were Greeks; and others, as Alfonzo Zamora or Pablo Coronell,[33] were converted Jews; yet, the names of Lopez de Zuniga, Nunez de Guzman, and Vergara[34] are a sufficient evidence of the success with which the co-operation of native scholars was enlisted in the undertaking.[35] * * * * *
