Restriction as to the Accumulation and the Reoccupation of Offices
Lastly, further seriously felt restrictions of the magistracy were involved in the prohibition issued in 412 against the accumulation of the ordinary curule offices, and in the enactment of the same date, that the same person should not again administer the same office under ordinary circumstances before an interval of ten years had elapsed, as well as in the subsequent regulation that the office which practically was the highest, the censorship, should not be held a second time at all (489). But the government was still strong enough not to be afraid of its instruments or to desist purposely on that account from employing those who were the most serviceable.
Brave officers were very frequently released from these rules,(16) and cases still occurred like those of Quintus Fabius Rullianus, who was five times consul in twenty-eight years, and of Marcus Valerius Corvus (384-483) who, after he had filled six consulships, the first in his twenty-third, the last in his seventy-second year, and had been throughout three generations the protector of his countrymen and the terror of the foe, descended to the grave at the age of a hundred.
16. Any one who compares the consular Fasti before and after 412 will have no doubt as to the existence of the above-mentioned law respecting re-election to the consulate; for, while before that year a return to office, especially after three or four years, was a common occurrence, afterwards intervals of ten years and more were as frequent. Exceptions, however, occur in very great numbers, particularly during the severe years of war 434-443. On the other hand, the principle of not allowing a plurality of offices was strictly adhered to.
There is no certain instance of the combination of two of the three ordinary curule (Liv. xxxix. 39, 4) offices (the consulate, praetorship, and curule aedileship), but instances occur of other combinations, such as of the curule aedileship and the office of master of the horse (Liv. xxiii. 24, 30); of the praetorship and censorship (Fast. Cap. a. 501); of the praetorship and the dictatorship (Liv. viii. 12); of the consulate and the dictatorship (Liv. viii. 12).
