According to the Roman de Rose, Denmark means the country of Danaos, who settled here with a colony after the siege of Troy, as Brutus is said by the same sort of name-legend to have settled in Britain. Saxo-Germanicus, with equal absurdity, makes Dan, the son of Humble, the first king, to account for the name of the country.
