Abstract
In his Gallic War Caesar tells us that the Roman Senate had frequently recognized the Aedui as ‘brothers and kinsmen’. This statement, though prima facie rather odd, is fully supported by Caesar's contemporaries, Cicero and Diodorus Siculus, and a number of later authorities. Ihm was of the opinion that the Aedui were recognized as ‘fratres consanguineosque’ because they were the first tribe in Gallia Comata to enter into alliance with Rome. However, no ancient authority supports this view and it is hardly sufficient to explain the notion of blood relationship implied by these titles
