Postumus Cominius Auruncus was a two-time consul of the early Roman Republic.
In 501 BC, Cominius was consul with Titus Larcius, who Livy says was appointed as the first dictator of Rome.
[14][15] A puzzling and textually incomplete passage in Festus[16][17] lists Cominius among several men who were burned publicly near the Circus Maximus in 486 BC.
Valerius Maximus says that a tribune of the plebs burned nine colleagues for conspiring with Spurius 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 and patrician status, this incident during the Volscian Wars remains mysterious.
