1. L.AemiliusMam. F. MAMERCUS, consul for the first time in B. C. 484 with K. FABIUS VIBULANUS, conquered the Volsci and Aequi, according to Livy, but suffered a defeat from them, according to the statement of Dionysius, who also says that Mamercus was in consequence ashamed to go into the city for the purpose of holding the comitia. (Liv. 2.42; Dionys. A. R. 8.83-87; Diod. 11.38.) He was consul a second time in B. C. 478 with C. Servilius Structus Ahala, and defeated the Veientines before the walls of their city with great slaughter. He subsequently concluded a treaty with them on terms which the senate regarded as too favourable, and was in consequence denied the honour of a triumph. (Liv. 2.49 ; Dionys. A. R. 9.16, 17; Diod. 11.52.) He was consul a third time in B. C. 473 with Vopiscus Julius Julus. For the events of this year see JULUS, No. 3, where the authorities are given. We learn from Dionysius (9.51) that he supported in B. C. 470 the agrarian law, on account of his hostility to the senate for having denied him a triumph.
