Otacilia Gens
sometimes written Octacilia, is first mentioned at the commencement of the first Punic war, when two brothers of this name obtained the consulship, M'. Otacilius Crassus in B. C. 263, and T. Otacilius Crassus in B. C. 261; but after this time the Otacilii rarely occur. The only cognomens in this gens are CRASUS and NASO. One or two persons, who were accidentally omitted under Crassus, are given below.
