"The Celtic Legend," published by Hersart de la Villemarque in 1864, clearly shows how the history of Bononia and of its celebrated tower is connected with his--St. Patrick's--life. One of the legends is entitled "St. Patrick," and commences as follows: "On the shore of the channel separating England from France, near the famous place from which Caesar embarked for the Isles of Britain, a fortified enclosure was erected overlooking and protecting the coast and territory which formed part of the possession of the Morini Gauls. This important strategic point was called in Latin, Tabernia, or the 'Field of Tents' (Le Champs du Pavilion), because the Roman army had pitched their tents there. About a mile distant, a group of buildings formed a fairly-sized village, which at first was called by the Gauls Gessoriac, _then Bonauen Armorik_, and afterwards named Bononia Oceasensis by the Roman Gauls, and finally Boulogne-sur-Mer by the French. "A light-house, or Nemtor, as it was called in the Celtic language, kept watch during the night over the camp, village, and sea, preserving the Gaulish frontier from piratical incursions. "At the foot of the light-house stood the residence of a Roman officer named Calphurnius, who had the supervision of the fire in the tower, amongst the more costly and ornamented houses than the others, where the free-and-easy life and customs of the Romans found a last refuge. He lived there attended by domestic and military servants. He had fought under the Imperial flag and attained the rank of a Decurion (p. 354). . . .
