Pliny the Elader, Natural History 33.19
It does not appear that rings were in common use before the time of Cneius Flavius, the son of Annius. This Flavius was the first to publish a table of the days for pleading, which till then the populace had to ascertain each day from a few great personages. The son of a freedman only, and secretary to Appius Cæcus, (at whose request, by dint of natural shrewdness and continual observation, he had selected these days and made them public), he obtained such high favour with the people, that he was created curule ædile; in conjunction with Quintus Anicius Prænestinus, who a few years before had been an enemy to Rome, and to the exclusion of C. Pœtilius and Domitius, whose fathers respectively were of consular rank. The additional honour was also conferred on Flavius, of making him tribune of the people at the same time, a thing which occasioned such a degree of indignation, that, as we find stated in the more ancient Annals, "the rings were laid aside!"
Most persons, however, are mistaken in the supposition that on this occasion the members of the equestrian order did the same: for it is in consequence of these additional words, "the phaleræ, too, were laid aside as well," that the name of the equestrian order was added. These rings, too, as the Annals tell us, were laid aside by the nobility, and not by the whole body of the senate. This event took place in the consulship of P. Sempronius and P. Sulpicius. Flavius made a vow that he would consecrate a temple to Concord, if he should succeed in reconciling the privileged orders with the plebeians: and as no part of the public funds could be voted for the purpose, he accordingly built a small shrine of brass in the Græ- costasis, then situate above the Comitium, with the fines which had been exacted for usury. Here, too, he had an inscription engraved upon a tablet of brass, to the effect that the shrine was dedicated two hundred and three years after the consecration of the Capitol. Such were the events that happened four hundred and forty-nine years after the foundation of the City, this being the earliest period at which we find any traces of the common use of rings.
