Corineus, or Corin, eponymous founder of Cornwall, was descended from theheroes of the Trojan War, and was one of the companions of Brutus ofBritain, and is spoken of in Geoffrey of Monmouth's Historia RegumBritanniae. He slew the giant Gogmagog near Plymouth, and for this featwas rewarded with possession of the southwestern horn of Britain, whichfrom then after was called "Corinea" or "Cornovia." The tale is preservedin the works of later writers, including Michael Drayton and John Milton,but later historians deem Corineus the Trojan to be a wholly legendaryfigure.
