Claudius
Claudius I, detail of a bust found near Priverno; in the Vatican Museums.
In 49 CE, the emperor Claudius extended the pomerium of Rome.1
The pomerium served as the sacred boundary of the city, defining the area where only Roman gods could be worshipped and where magistrates exercised civil, rather than military, authority. By expanding this boundary, Claudius exercised his authority as a censor, a role he assumed in 47 CE as part of his broader efforts to respect and revive traditional Roman religious practices.21
