Legendary Duke of Cornwall

In Arthurian legend, Gorlois (Gwrlais) of Tintagel was the Duke of Cornwall. He was the first husband of King Arthur's mother Igraine and the father of her daughters, Arthur's half sisters. Her second husband was Uther Pendragon, the High King of Britain and Arthur's father, who marries her after killing him.

The name Gorlois first appears in Geoffrey of Monmouth's Historia Regum Britanniae (c. 1136). Prose Merlin and Of Arthour and of Merlin call him Duke Hoel (Höel) of Tintagel, the latter text describing him as Igraine's second husband but also prior to her marriage with Uther. In Perlesvaus, he appears as King Goloé (Golaas).

According to Historia Regum Britanniae, Gorlois was vassal of Ambrosius Aurelianus, whose arrival at the Battle of Kaerconan ensured 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. In the Brut Tysilio, a Welsh version of Geoffrey's work, Gorlois is the father of Cador, Duke of Cornwall, presumably by Igraine. After he succeeds his brother, Ambrosius, Uther holds a feast for his nobles, and seeing Igraine, falls in love with her. Sensing Uther Pendragon's interest, Igraine asks her husband to take her back home to Cornwall. He placed her at the more defensible Tintagel Castle, while he prepared to defend his territory from Dimilioc. Incensed at their departing without leave, Uther lays siege to Gorlois' castles to little effect. He consults his friend Ulfin who tells him that the lady can hardly look favorably on someone who makes war on her husband, and suggests the king seek advice from Merlin in gaining access to Tintagel. Merlin devises an enchantment that disguises Uther in the form of Gorlois. In this form he approaches Igraine and they sleep together, conceiving Arthur. Unbeknownst to either of them, the real Gorlois has been killed that very night in battle against Uther's troops. The text can be read with either Gormant or Ricca being Arthur's half brother, and is a parallel to later stories of Gorlois and Igraine. Scholars Rachel Bromwich and D. Simon Evans note the similarity between the Gor element in Gormant and Gorlois' names, which may equate them, or could reflect a known practice in some late antiquity and early medieval European dynasties to share a name prefix. Ricca could be an earlier name given to the husband of Igraine, or could be equated with Ricatus, a possible later king of Cornwall. The Peniarth triads give the same title—Arthur's chief elder at Celliwig, Cornwall—to Caradoc, which could also equate him with either Ricca, or his father. Richard Carew's Survey of Cornwall (1602) places Gorlois as husband of Igerna and duke of Cornwall in 500 AD, who is succeeded by Earl Cador by 526 AD. The Book of Baglan (1600–1607) calls him Gurleis, Goulisor, or Gwrleis, duke or prince of Cornwall, and husband of Eigyr; he is the father of Cador, and son of Sortogus, a direct male line descendant of Maxentius, Dyfnwal Moelmud, Camber and Brutus of Troy. William Worcester travelled to Cornwall in 1478, and recorded in his Itineraries that "Tador Duke of Cornwall, husband of the mother of Arthur was slain" at Castle an Dinas. This is generally interpreted as a conflation of Gorlois with Cador, and as an alternative place of Gorlois' death, differing from the Historia Regum Britanniaes account that he died at Dimilioc.

Henry Jenner considered Gorlois to be a real fifth or sixth century figure, either a petty chief and vassal of the Royal House of Dumnonia, or of the line of the original chiefs of the Dumnonii if the kings of Dumnonia were the leaders of the Britons displaced by the Saxons. He suggested that Bosworlas (in St Just) and Treworlas were place names taken from Gorlois, and notes that Bosworlas is very close to Bosigran .
