Life of Camillus by Plutarch
XXIV. Resumption of consular elections, One Consul had to be a plebeian, dedication of the temple of Concord (peace between the social orders)
A great conflict of opposite opinions arose in the senate; but, at last, the most moderate and most acceptable to the people prevailed, and consent was given, that of two consuls, one should be chosen from the commonalty. When the dictator proclaimed this determination of the senate to the people, at the moment, pleased and reconciled with the senate, as indeed could not otherwise be, they accompanied Camillus home, with all expressions and acclamations of joy; and the next day, assembling together, they voted a temple of Concord to be built, according to Camillus’s vow, facing the assembly and the forum; and to the feasts, called the Latin holidays, they added one day more, making four in all; and ordained that, on the present occasion, the whole people of Rome should sacrifice with garlands on their heads. In the election of consuls held by Camillus, Marcus Aemilius was chosen of the patricians, and Lucius Sextius the first of the commonalty; and this was the last of all Camillus’s actions. In the year following, a pestilential sickness infected Rome, which, besides an infinite number of the common people, swept away most of the magistrates, among whom was Camillus; whose death cannot be called immature, if we consider his great age, or greater actions, yet was he more lamented than all the rest put together that then died of that distemper.
