 As governor of Gaul, Drusus made his headquarters at Lugdunum, where he decided to establish the "concilium Galliarum" or ‘council of the Gaulish provinces’ sometime between 14 and 12 BC.This council would elect from its members a priest to celebrate games and venerate Rome and Augustus as deities every 1 August at the altar of the three Gauls that Drusus established at Condate in 10 BC.Drusus' son Tiberius—the future emperor Claudius—was born in Lugdunum on the same day that this altar was inaugurated.
