The author of the Lex Maenia
which provided for repeating a day of the circus games (Macrob. Sat. 1.11.5), may also be the Maenius, Tr. Pl., who carried a plebiscite which placed the patrum auctoritas before elections (Cic. Brut. 55; cf. Planc. 8). (Broughton MRR I)
A similar story of the instauration of the games, dated in 490 (Fab. Pict., fr. 15, Gell. fr. 21, and Coelius fr. 49 Peter, all in Cic. Div. 1.55; cf. Liv. 2.36; Dion. Hal. 7.69; Val. Max. 1.7.4) makes the dating in 279 quite uncertain, though a law regularizing the practice may be dated then. The election law should be dated after 292, when Book 10 of Livy ends, and was placed by Lange in 287 (2.116) in connection with the Lex Hortensia. See 298, Tribunes of the Plebs, on Curius Dentatus. Macrobius' notice, as he used the Capitoline era (Somn. Scip. 2.11.16), refers to 279 B. C. (Broughton MRR I)
His law made the [atrum auctoritas precede electoral assemblies (Cic. Brut. 55; Planc. 8), and, though probably about 287 B.C., must precede 219 (Mommsen, Str. 3.1042; Rotondi 248f.; Niccolini FTP 391; cf. Lange 2.116). (Broughton MRR I)
