Postumus Cominius Auruncus was a two-timeconsul of the earlyRoman Republic.

In 501 BC, Cominius was consul withTitus Larcius, whoLivy says was appointed as the firstdictator of Rome.^[2][3] Other sources indicate the beginnings of hostilities with theLatins and a conspiracy amongslaves during their term.^[4][5][3]

As the consuls of 493 BC, Cominius andSpurius Cassius Vecellinus were elected towards the end of theFirst secessio plebis in 494 BC.^[6] They also conducted acensus.^[7][8]

Cominius achieved amilitary victory against theVolsci. He initially defeated a force from the town ofAntium, then took the towns ofLongula (to the north of Antium) andPollusca. He laid siege to the town ofCorioli and despite being attacked by a second force of Volsci from Antium, he achieved victory through the distinguished actions ofGaius Marcius Coriolanus, and captured Corioli.^{[9][10][11][12][13]}

In 488, he was among the envoys(legati), all of consular rank, sent to Coriolanus.^[14][15]

A puzzling and textually incomplete passage inFestus^[16][17] lists Cominius among several men who were burned publicly near theCircus Maximus in 486 BC.Valerius Maximus says that atribune of the plebs burned nine colleagues for conspiring withSpurius Cassius Vecellinus, a consul in this year who plotted to make himself king.^[18][19] Since the plebeian tribunes numbered ten only much later, and since the listed names indicate that the men were of consular rank andpatrician status, this incident during theVolscian Wars remains mysterious.^[20]
