The gens Aternia, also written Aeternia, was a patrician family at ancient Rome. The only member of this gens to appear in history was Aulus Aternius Varus, consul in 454 BC, and later one of the only patricians ever to be chosen tribune of the plebs. Other Aternii are known from inscriptions. Branches and cognomina The only surnames of the Aternii in Republican times are Varus and Fontinalis. Varus belongs to a large class of cognomina originally derived from the physical characteristics of the bearer, and indicated someone "knock-kneed"; that is, with inwardly-turned legs. Fontinalis is derived from , and must have indicated someone who lived near a spring; it belongs to a common class of surname derived from the names of everyday objects. Members Aulus Aternius Varus, surnamed Fontinalis, was consul in 454 BC. He and his colleague, Spurius Tarpeius Montanus Capitolinus, passed a law regulating fines. Six years later, Aternius and Tarpeius were chosen tribunes of the plebs, when only five candidates received sufficient votes for election, and Marcus Duilius, presiding over the election, instructed these five to co-opt five colleagues. Although patricians, they were favourably disposed to the interests of the plebs, and so acceptable to their colleagues.
