"VI Victrix
Formed; 41-40? (Octavian); Perusia, 41; movements not reported, 40-31; Spain, 30 BC onwards-AD 69.
Emblem: often stated to have a bull-emblem, suggesting (false) Caesarian antecedents, but the evidence is insecure.
Titles: Hispaniensis, 'stationed in Spain'. Attested: AE 1917/1918, 2 (Neronian); CIL V4381 = Sup.677; PBSR xli (1973), 12. Victrix (Victorious); first attested: ILS 2648 (Neronian)-that inscription notes a recent victory contra Astures, perhaps the occasion for the award; but AE 1968, 2206 may be earlier."
