The Os Lusiades, an epic poem, that has been called "one of the noblest monuments ever raised to the national glory of any people," was written by Luis de Camoens, a Portuguese of the sixteenth century. It is intensely patriotic, although it is touched by both Greek mythology, and the Italian style, which during this epoch had been slightly blended with the Portuguese. Portugal had little or no influence on the literature of any nation but her own, receiving her strongest impressions from outsiders. In the eighteenth century she was dominated both in taste and manners by the French, and the beginning of the nineteenth century found her a great admirer and imitator of English literature. National songs are known to have been sung in Portugal during the earliest times; but none of them have come down to us. They were doubtless similar to the other bardic songs of Europe. FRENCH. It is in the first ages of national existence that the foundations of national character and poetry are laid; and the farther back that history is studied, the more closely do we find the different peoples of the world united in their literature. Its first history in France is undoubtedly that of the Troubadours. Provence, where it originated, early became an independent kingdom, while in the north the literature of the Trouveres became the foundation of the national literature of France. Latin was the language of the country after its conquest by Julius Caesar; then came the Northern hordes, when language became corrupted, until, in the time of Charlemagne, German was the Court language, Latin the written language, and the Romance dialect, still in its barbaric state, was the speech of the people. The Gauls in the North, who used the Romance, were also called the Roman-Wallons; they were distinguished from Charlemagne's German subjects, while in the South the natives were called the Romans-Provencaux. In the tenth century the Normans invaded France, and infused another element in the language, which gradually became Norman-French; and from the twelfth century the two dialects were known as Provencal and French. The Provencal dialect, although much changed, is still spoken in Provence, Languedoc, Catalonia, Valencia, Majorca, and Minorca, while the French was brought, by gradual polish, to its present perfection. The Troubadours who flourished for three centuries, from 950 to 1250, used the Romance language in their poems. The brilliance of this period of literature, its sudden rise, and as sudden disappearance, is not unlike the rise and fall of the Arabian literature.
