as a leader who takes charge of Uther's host when they are attacked by Gorlois while Uther is secretly lying beside Igraine in Tintagel. Most works, such as the English Alliterative Morte Arthure and Malory's Le Morte d'Arthur, however, call Cador Arthur's "cousin", though in the Alliterative text Arthur calls Cador his sister's son. 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 sometimes read as Cador, and is generally interpreted as a conflation of Cador with Gorlois (the husband of Igraine in Historia Regum Britanniae), but likely reflects a local tradition, as the Historia is the only authority for Gorlois as Igraine's husband. In The Dream of Rhonabwy, a medieval romance associated with the Mabinogion Cador is "Cadwr Earl of Cornwall, the man whose task it is to arm the king on the day of battle and conflict" – i.e. at the Battle of Badon Hill, which the writer situates close to the upper River Severn.
