Lampridius, in his life of Alexander Severus, tells us of a "Druid" sorceress who warned the Emperor of his approaching doom. Another such "Druidess" is said to have foretold Diocletian's rise. See Coulanges, 'Comme le Druidisme a disparu,' in the Revue Celtique, iv. 37.
See Professor Rhys, 'Celtic Britain,' p. 70. The Professor's view that the "schismatical" tonsure of the Celtic clergy, which caused such a stir during the evangelization of England, was a Druidical survival, does not, however, seem probable in face of the very pronounced antagonism between those clergy and the Druids. That tonsure was indeed ascribed by its Roman denouncers to Simon Magus [see above], but this is scarcely a sufficient foundation for the theory.
They may very possibly have been connected with the Veneti of Venice at the other extremity of "the Gauls."
