Ambrosius Aurelianus
In Arthurian legend, Gorlois () of Tintagel, Duke of Cornwall, is the first husband of Igraine, whose second husband is Uther Pendragon. Gorlois's name first appears in Geoffrey of Monmouth's "Historia Regum Britanniae" (). A vassal of Ambrosius Aurelianus, his arrival at the Battle of Kaerconan ensures the defeat of Hengist. In Wace's "Roman de Brut", when Hengist's son Octa and his cousin Ossa rebel, Gorlois helps Uther defeat them at York.
