Caecus' political highlight is his time as censor for five years, which was only supposed to last 18 months. During his time as a censor he built the first Roman road (the Via Appia) and the first aqueduct (the Aqua Appia). He also made several obscure constitutional reforms; he changed the organization of Roman tribes and admitted descendants of freedmen in to the electoral rolls. In addition, he was the first censor to draw the list of senators. These reforms massively increased the prestige of the censorship position, which before had only been a minor magistracy.
