Aebutius was elected consul for the year 442, with Marcus Fabius Vibulanus.
Their year of office was peaceful, and commissioners were appointed to establish a colony at Ardea.
Many Romans wanted the colony to receive the majority of the land distributed, but it was decided to allot it first to the Rutuli, who were native to Ardea, and give the Roman colonists the remaining land.
They entered Roman territory, and crossing the Anio, advanced almost as far as the Colline Gate, when Quintus Servilius Priscus was appointed dictator.
Postumus Aebutius was named magister equitum, and the two gathered a volunteer force just outside the gate.
