However, Camulodunum was retaken, either by Tasciovanus or by his son Cunobelinus, who succeeded him ca AD 9 and ruled for about 30 years. Little is known of Cunobelinus's life, but his name survived into British legend, culminating in William Shakespeare's play "Cymbeline". Geoffrey of Monmouth says he was brought up at the court of Augustus and willingly paid tribute to Rome. Archaeology indicates increased trading and diplomatic links with the Roman Empire. Under Cunobelinus and his family, the Catuvellauni appear to have become the dominant power in south-eastern Britain. His brother Epaticcus gained territory to the south and west at the expense of the Atrebates until his death ca AD 35. The grave of the "Druid of Colchester" dates to this period, providing evidence of medical practices and technology within the Catuvellauni tribe.
