 Her Aventine Temple served the plebeians as cult centre, legal archive, treasury and possibly law-court; its foundation was contemporaneous with the passage of the Lex Sacrata, which established the office and person of plebeian aediles and tribunes as inviolate representatives of the Roman people.Tribunes were legally immune to arrest or threat, and the lives and property of those who violated this law were forfeit to Ceres.The Lex Hortensia of 287 BC extended plebeian laws to the city and all its citizens.
