2) Rubrius, tribune of the plebs with C. Gracchus in 631 = 123, with whom he proposed a law towards introducing a colony in Carthage (Plut. C. Grinch. 10, 1), which is listed as the Lex Rubria in the lex repetundarum (CIL I 198 = Mommsen Jur. Schr. I 31) c. 22 and in the lex agraria (CIL I 200 = Mommsen loc. cit. 86) c. 59. <10> We can take it to be certain that this law, and Rubrius’ tribunate alongside it, belongs in the year 631 = 123 and not in the following (cf. Mommsen loc. cit. 121, also 53. Kornemann Klio Beiheft I 46f. Ed. Meyer Kl. Schr. 413 Anm.). <20> Since the lex repetundarum was passed by his colleague M’. Acilius Glabrio (see above vol. I p.256 nr. 37), these two tribunes were surely also the authors of a lex Rubria Acilia, named after them both, the content of which is unclear. This law is cited in a senatus consultum for Astypalaia in 649 = 105 (IG XII 3, 173) c. 12. Perhaps this Rubrius is identical with Rubrius nr. 9.
