Succeeded Addedomaros to the Trinovantian throne in c.10-5BC and ruled for several years before being supplanted by Cunobelin of the Catuvellauni. Like his contemporary Tincommius of the Atrebates, he appeared as a suppliant to Augustus and paid tribute on the Capitol in Rome before 7AD. He should not be confused with Dubnovellaunus of the Cantiaci.
