Arviragus, known as Cadwal, is Cymbeline’s second son, but is aware of this fact as he was kidnapped at the age of two by Belarius and brought up by him as a hunter in a cave along with his elder brother Guiderius.
Twenty years later, he is growing irritated at being brought up like an animal and wishes to have some experiences to talk about when he’s old. He is a great hunter and hopes for a chance to be a great warrior. He feels an immediate sympathy for the boy Fidele and adopts him as his brother. He is heart-broken at the boy’s death, but delighted to later discover that firstly, he’s still alive and secondly, he’s actually their sister Imogen. He insists in going to fight the Roman invasion, no matter what Belarius says, and distinguishes himself in the battle along with Guiderius and Belarius, saving the King’s life and turning back the tide of fleeing Britons. He is a fairly simple-minded fellow, both eager for glory and tender-hearted.
