The name Livineius seems to belong to the family of the Reguli itself, originally at least a branch of the Gens Atilia. In Cicero (Cic. Att. 3.17, ad Fam. 13.60) it is the appellation of two freedmen of the brothers M. and L. Regulus, one of whom, L. Livineius Trypho, Cicero commends to C. Munatius, as having befriended when others deserted him (ad Fam. 1. c.); compare Tac. Ann. 3.11, 14.17. [REGULUS.]
