a family name of the Acilia Gens at Rome. The Acilii Glabriones were plebeian (Liv. 35.10, 24, 36.57), and first appear on the consular Fasti in the year B. C. 191, from which time the name frequently occurs to a late period of the empire. The last of the Glabriones who held the consulate was Anicius Acilius Glabrio Faustus, one of the supplementary consuls in A. D. 438.
