In 192 Commodus renamed Rome Colonia Commodiana and applied his names to months and institutions as Dio prints. This Fact is that renaming programme. It was reversed after his death; reversal is a neighbouring aftermath row.

Context

Renaming the city for a living man is a polarising identity policy. Senatorial sources treat it as tyranny; they are the surviving file.

Commodus’s documented role is bounded by other offices and collaborators named in the sources below.

Dio lists renamings of Rome, the legions, the months, and other headings to Commodus/Hercules types in 192. Coins and the hostile narrative meet.

Why it matters

Civic renaming to a living emperor is a polarisation path. Confidence high on the heading in Dio, medium on the full list.

What the sources establish

Loeb Dio and Britannica independently record the 192 renaming cluster.

Established: 192 Colonia Commodiana programme as received. Not established: that every street sign changed.

Commodus did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A new city-name is not damnatio. Split his act from the senate’s later erasure.
