Trebellianus
one of the most insignificant and despicable of the herd of thirty tyrants enumerated by Pollio [see AUREOLUS]. He was a Cilician robber, who called his castle in the fastnesses of the Isaurian mountains the Palatium, established a mint, and gave himself the title of emperor. But having been tempted to quit his stronghold and descend into the plain, he was there encountered and slain by Causisoleus, an Egyptian, one of the generals of Gallienus. (Trebell. Poll. Trig. Tyrann. xxv.)
