On 17 July 2021, an important and rare discovery was made during archaeological works carried out near the recently restored Mausoleum of Augustus in the Piazza Augusto Imperatore, just off the Via del Corso in Rome. A sizable travertine block (pomerium cippus) was unearthed, which defined the sacred boundary (pomerium) of Rome extended by Emperor Claudius in 49 AD. Although the discovered block is only partially preserved, with he censorial power of the the ruler (line 6) and a final formula:
[au]ctis populi R[omani] / finibus, pomerium / ampliavit terminavitque
(lines 7 – 9)
linking this inscription to the activities of Claudius and similar cippi is most reasonable.
Why is the recent discovery in Rome so unique and of such a great significance?
