From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
But the important change made in the year 333 in respect to the quaestorship amply compensated for this success of the patrician party.
The patricio-plebeian assembly of the tribes--perhaps taking up the ground that at least the two military paymasters were in fact officers rather than civil functionaries, and that so far the plebeian appeared as well entitled to the quaestorship as to the military tribuneship--carried the point that plebeian candidates also were admitted for the quaestorial elections, and thereby acquired for the first time the privilege of eligibility as well as the right of election for one of the ordinary magistracies.
With justice it was felt on the one side as a great victory, on the other as a severe defeat, that thenceforth patrician and plebeian were equally capable of electing and being elected to the military as well as to the urban quaestorship.
