one of the several persons to whom the murder of Galba, in A. D. 69, was attributed. He carried the bleeding head of the emperor, which, from its extreme baldness, was difficult to hold, in the lappet of his sagum, until, compelled by his comrades to expose it to public view, he fixed it on a spear and brandished it, says Plutarch, as a bacchanal her thyrsus, in his progress from the forum to the praetorian camp (Plut. Galb. 27; comp. Sueton. Galb. 20). But for the joint statement of Plutarch (l.c.) and Tacitus (Tac. Hist. 1.44), that Vitellius put to death all the murderers of Galba, this Fabullus might be supposed the same with Fabius Fabullus, legatus of the fifth legion, whom the soldiers of Vitellius, A. D. 69, chose as one of their leaders in the mutiny against Alienus Caecina [CAECINA, No. 9], when he prematurely declared for Vespasian. (Tac. Hist. 3.14.)
