Victor Vitensis (de Persecut. Vandal. 1. i. c. 6, p. 8, edit. Ruinart) calls him, acer consilio et strenuus in bello: but his courage, when he became unfortunate, was censured as desperate rashness; and Sebastian deserved, or obtained, the epithet of praeceps (Sidon. Apollinar. Carmen ix. 281) . His adventures at Constantinople, in Sicily, Gaul, Spain, and Africa, are faintly marked in the Chronicles of Marcellinus and Idatius. In his distress he was always followed by a numerous train; since he could ravage the Hellespont and Propontis and seize the city of Barcelona.
