Cicero remarks on the existence among the Gauls of augurs or soothsayers, known by the name of Druids, with one of whom, Divitiacus, an Aeduan, he was acquainted.
The trabea, which in historical times was worn by the consuls when opening the temple of Janus, by the equites at their yearly inspection and on some other occasions, and by the Salii at their ritual dances, and had (according to tradition) formed the original costume of the augurs and flamens (who afterwards adopted the toga praetexta), was apparently a toga smaller in size than the ordinary civil dress, decorated with scarlet stripes (trabes).
He was also a member of the college of augurs.
In many nations divination and priesthood have always gone hand in hand; at Rome, for example, the augurs and the XV viri sacrorum, who interpreted the Sibylline books, were priestly colleges.
And it is instructive to observe that when the plebeians extorted their full share of political power they also demanded and obtained admission to every priestly college of political importance, to those, namely, of the pontiffs, the augurs, and the XV viri sacrorum.
