Gorlois

In Geoffrey of Monmouth's pseudo-historical account and later Arthurian retellings Gorlois is presented as the ruler (Duke or lord) of Cornwall and husband of Igraine. In Geoffrey's version, Uther Pendragon desires Igraine; Merlin devises an enchantment that disguises Uther as Gorlois so that Uther can approach Igraine and they conceive Arthur, while the real Gorlois is killed in battle that same night. Variant medieval texts render the same regional figure under different names (Culhwch and Olwen calls him Rica; the Prose Merlin and some later traditions call him Hoel/Hoël of Tintagel), and antiquarian writers sought to localize him in Cornish sites and genealogies, producing layered and sometimes contradictory origin accounts.

Primary sources and summaries do not give a consistent physical description of Gorlois as an individual; he is described and characterized by office and location rather than bodily detail. He is repeatedly identified as the ruler or duke of Cornwall and the lord of Tintagel Castle (or alternative Cornish strongholds in variant accounts), and narrative attention centers on his role as husband and military defender. In later dramatic treatments (notably Thomas Hughes' The Misfortunes of Arthur) he is briefly presented as a spectral figure who returns to condemn Arthur for Uther's treachery, but this ghostly depiction is a secondary literary device rather than a standard element of the medieval corpus.

Gorlois is not attributed supernatural powers in the cited sources; his abilities are political and military. He places his wife Igraine in the defensible seat of Tintagel and prepares to defend his domain against Uther's forces, and he dies in combat defending his holdings. The magical action in his story is performed by Merlin—an enchantment that disguises Uther as Gorlois—rather than any magic of Gorlois himself. His narrative role also includes dynastic influence: in later traditions he is named father (or stepfather figure) to daughters who become important alliance-makers (Morgan, Morgause, Elaine in later Malorian genealogies) and is associated in some sources with regional successors such as Cador or with figures named Rica/Gormant in Welsh material.
