Guideʹrius

The elder son of Cymbeline, a legendary king of Britain during the reign of Augustus Cæsar. Both Guiderius and his brother Arvirʹagus were stolen in infancy by Belaʹrius, a banished nobleman, out of revenge, and were brought up by him in a cave. When grown to man’s estate, the Romans invaded Britain, and the two young men so distinguished themselves that they were introduced to the king, and Belarius related their history. Geoffrey of Monmouth says that Guiderius succeeded his father, and was slain by Hamo. (Shakespeare: Cymbeline.)
