Guido,
surnamed the Savage (in Orlando Furioso), son of Constanta and Amon, therefore younger brother of Rinaldo. He was also Astolphos kinsman. Being wrecked on the coast of the Amazous, he was doomed to fight their ten male champions. He slew them all, and was then compelled to marry ten of the Amazons. He made his escape with Aleria, his favourite wife, and joined the army of Charlemagne.
