St. Vulgan, of Ireland, Confessor
[Titular saint of the Collegiate Church, and patron of the town of Lens, in Artois.] He was an Irishman, (or, according to his manuscript life kept at Lens, an Englishman or Briton,) who preached the faith some time in those parts, and died in a cell not far from the abbey of St. Vedast at Arras, soon after it was erected in the seventh century. Colgan calls him a bishop, and places his death about the beginning of the eighth century. A portion of his relics is kept in the abbey of Liesse, brought from Lens. See Basseur, Thes. reliq. Hannoniæ, p. 163. Also Miræus, Fasti Belgici, p. 647; Colgan, Act. SS. Hib. p. 377, n. 5. Molanus, &c.
