a son of the rhetorician M. Annaeus Seneca, and an elder brother of the philosopher Seneca. His original name was M. Annaeus Norattus, but he was adopted by the rhetorician Junius Gallio, whereupon he changed his name into L. Junius Annaeus (or Annaeanus) Gallio. Dio Cassius (60.35) mentions a witty but bitter joke of his, which he made in reference to the persons that were put to death in the reign of Claudius. His brother's death intimidated him so much, that he implored the mercy of Nero (Tac. Ann. 15.73); but according to Hieronymus the chronicle of Eusebius, who calls him a celebrated rhetorician, he put an end to himself in A. D. 65. He is mentioned by his brother in the preface to the fourth book of the and the work de Vita Beata is addressed to him.
