Senecio, Herennius
was a native of Baetica in Spain, where he served as quaestor. He was put to death by Domitian on the accusation of Metius Carus, who charged him with having been a candidate for no public office after the quaestorship, and with having written the life of Helvidius Priscus. He wrote the latter work at the request of Fannia, the wife of Helvidius. (D. C. 67.13; Tac. Agr. 2, 45; Plin. Ep. 1.5, 4.7, 11, 7.19, 33.)
