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.
