As the dangers which menaced the Eastern Empire at the close of the Fourteenth century increased, the most learned of the Greeks fled to the West, carrying with them the treasures of their language. Amongst the first of these was Emanuel Chrysoloras, who settled in Florence in 1395 as public teacher in Greek. He had been previously known as an Ambassador from Constantinople to the Western powers, his mission being to solicit aid against the Turks. From Florence he proceeded to various Italian Universities, and became the preceptor of several early Hellenists. In 1423, 238 manuscripts of Greek authors were brought into Italy by John Aurispa of Sicily, who thus put his country in possession of authors hardly known to her by name. By means of these, and the labours of Philelfo and other collectors, an ardent thirst for Classical and especially Grecian Literature began to make itself manifest, which about the year 1440 was completely developed. The kings of France and the Dukes of Burgundy were at this period the most munificent patrons of learning and literature. The fashion they set was followed by their chief nobles, and many celebrated libraries were formed in their dominions. The Library of the Louvre was founded by King John of France in 1350. His third son, Jean, Duc de Berri, formed one at his Chateau de Bicêtre, near Paris, only inferior to that of his father. Philippe le Hardi, the youngest son, who became Duke of Burgundy, was also addicted to the collection of fine books, “and spared no expense in the employment of artists to adorn his library, and in the purchase of their most choice productions.” His son, Jean sans Peur, inherited his father’s tastes and added to the collections already made. “But all previous patronage sinks into comparative insignificance before the encouragement given to everything connected with literature by Philippe le Bon, who succeeded Jean in 1419. At Bruges where he kept his Court, he gave continual employment to multitudes of authors, translators, copyists, and painters, who were constantly enriching his library with their best productions.” In an account of the Duke’s library, nearly two thousand works are enumerated, “the greater part being magnificent vellum folios beautifully illuminated, bound in velvet, satin, or damask, studded with gems, and protected by gold clasps jewelled and chased.” “The passion for books thus displayed was not confined to France or the French princes. In Italy, Germany, England, and other countries, the same taste spread. In England Henry VI had a valuable library; many books written and illuminated for him being still among the royal MSS. in the British Museum. The Duke of Bedford, whose love of literature was probably greatly stimulated while Regent of France, was surpassed by none of his countrymen in his patronage of the Fine Arts; and the celebrated Missal executed for him still remains as one of the choicest productions of his age.
