From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Both consuls and tribunes had full and co-ordinate criminal jurisdiction, although the former exercised it indirectly, and the latter directly; as the two quaestors were attached to the former, the two aediles were associated with the latter.(7)
7. That the plebeian aediles were formed after the model of the patrician quaestors in the same way as the plebeian tribunes after the model of the patrician consuls, is evident both as regards their criminal functions (in which the distinction between the two magistracies seems to have lain in their tendencies only, not in their powers) and as regards their charge of the archives.
The temple of Ceres was to the aediles what the temple of Saturn was to the quaestors, and from the former they derived their name. Significant in this respect is the enactment of the law of 305 (Liv. iii. 55), that the decrees of the senate should be delivered over to the aediles there (p. 369), whereas, as is well known, according to the ancient --and subsequently after the settlement of the struggles between the orders, again preponderant--practice those decrees were committed to the quaestors for preservation in the temple of Saturn.
