The literary development above referred to ceased almost entirely toward the end of the fourteenth century, and later, during the union with Denmark, the Danish language gradually took the place of the old Norse as a book-language, and the literature became essentially Danish. Copenhagen, with its court and its university, was the literary and educational centre, where the young men of Norway went to study, and authors born in Norway became, to all intents and purposes, Danish writers. But Norway furnished some valuable contributors to this common literature. One of the very first names on the records of the Danish literature, Peder Claussön (1545-1614), is that of a Norwegian, and the list further includes such illustrious names as Holberg, Tullin, Wessel, Steffens, etc. One of the most original writers whom Norway produced and kept at home during the period of the union with Denmark was the preacher and poet, Peder Dass (1647-1708). The best known among his secular songs is "Nordlands Trompet," a beautiful and patriotic description of the northern part of Norway. Ludvig Holberg was born in Bergen, Norway, December 3, 1684. His father, Colonel Holberg, had risen from the ranks and distinguished himself, in 1660, at Halden. Shortly after his death the property of the family was destroyed by fire, and at the age of ten years Ludvig lost his mother. It was now decided to have him educated for the military service; but he showed a great dislike for military life, and, at his earnest request, was sent to the Bergen Latin School. In 1702 he entered the University of Copenhagen. Being destitute of means, he took a position as private tutor. As soon as he had saved a small sum he went abroad. He was first in Holland, and afterward studied for a couple of years at Oxford, where he supported himself by giving instruction in languages and music. Upon his return to Copenhagen he again took a position as private tutor and had an opportunity to travel as teacher for a young nobleman. In 1714 he received a stipend from the king, which enabled him to go abroad for several years, which he spent principally in France and Italy. In 1718 he became a regular professor at the Copenhagen University. Among Holberg's many works the following are the most prominent: "Peder Paars," a great comical heroic poem, containing sharp attacks on many of the follies of his time; about thirty comedies in Molière's style, and a large number of historical works. Holberg, who was ennobled in 1747, died in January 29, 1754, and was buried in Sorö Church. His influence on the literature and on the whole intellectual life of Denmark was very great. He is often called the creator of the Danish literature.
