GOSLIN or GAUZLINUS (d. c. 886), bishop of Paris and defender of the city against the Northmen (885), is variously described as the son of Roricon II., count of Maine and the natural son of the emperor Louis I. In 848 he entered a mon astery at Reims; later he became abbot of St. Denis. He took a prominent part in the struggle against the Northmen, by whom he and his brother Louis were taken prisoners (858), and he was released only after paying a heavy ransom (Prudentii Tre censis episcopi Annales, ann. 858). From 8S5 to 867 he held intermittently, and from 867 to 881 regularly, the office of chancellor to Charles the Bald and his successors. In 883 or 884 he was elected bishop of Paris, and foreseeing the dangers to which the city was to be exposed from the attacks of the Northmen, he strengthened the defences, though he also relied for security on the merits of the relics of St. Germain and St. Genevieve. The city was attacked on Nov. 26, 885, and the struggle for the possession of the bridge (now the Pont-au Change) lasted for two days; but Goslin repaired the destruction of the wooden tower overnight, and the Normans were obliged to give up the attempt to take the city by storm. The siege lasted for about a year longer, while the emperor Charles the Fat was in Italy. Goslin died soon after the preliminaries of the peace had been agreed on, worn out by his exertions, or killed by a pestilence which raged in the city.
