a native of Cisalpine Gaul, was the first person that ever set up a school at Rome for the purpose of teaching Latin and rhetoric, about B. C. 88. Cicero in his boyhood knew him. and would have liked to receive instruction from him in Latin, but his friends prevented it, thinking that the study of Greek was a better training for the intellect. L. Plotius lived to a very advanced age, and was regarded by later writers as the father of Roman rhetoric. (Sueton, De clar. Rhet. 2; Hieron. in Euseb. Chron. Ol. 173, 1 ; Quint. Inst. 2.4.44; Senec. Controv. ii. prooem.) Besides a work de Gestu (Quint. Inst. 11.3 § 143), he wrote judicial orations for other persons, as for Atratinus, who in B. C. 56 accused M. Coelius Rufus. (Comp. Cic. Fragm. p. 461; Schol. Bob. ad Cic. p. Arch. p. 357, ed. Orelli; Varro, de L. L. 8.36.)
