was the leader of the plebs in their secession to the Sacred Mountain, B. C. 494, and was afterwards one of the first tribunes of the plebs elected in that year. (Liv. 2.32, 33; Dionys. A. R. 6.45, 70, 72, 82, 89.) He was plebeian aedile in 492 (Dionys. A. R. 7.14), and tribune again in 491, when he distinguished himself by his attacks upon Coriolanus, who was brought to trial in that year. (Dionys. A. R. 7.33_39, 61.) Asconius calls him (in Cornel. p. 76, ed. Orelli) L. Sicinius L. f. Bellutus.
It is most probable that his descendants, one of whom we are expressly told was tribune in B. C. 449 (Liv. 3.54), also bore the cognomen Bellutus; but as they are not mentioned by this name in ancient writers, they are given under SICINIUS.
