Tiberius Claudius Cogidubnus

Tiberius Claudius Cogidubnus (or Cogidumnus, Togidumnus or similar) was a 1st-century king of the Regnenses or Regni tribe in early Roman Britain.

Chichester and the nearby Roman villa at Fishbourne, believed by some to have been Cogidubnus' palace, were probably part of the territory of the Atrebates tribe before the Roman conquest of Britain in AD 43. Cogidubnus may therefore have been an heir of Verica, the Atrebatic king whose overthrow prompted the emperor Claudius to invade. After the conquest the area formed part of the civitas of the Regnenses / Regni, possibly Cogidubnus' kingdom before being incorporated into the Roman province. The public baths, amphitheatre and forum in Silchester were probably built in Cogidubnus' time.

In Tacitus's Agricola, published ca. 98, where his name appears as "Cogidumnus" in most manuscripts and "Togidumnus" in one, he is said to have governed several civitates (states or tribal territories) as a client ruler after the Roman conquest, and to have been loyal "down to our own times" (at least into the 70s).

He is also known from an inscription on a damaged slab of marble, found in Chichester in 1723 and datable to the late 1st century. As reconstructed by J.E. Bogaers, it reads (reconstructed parts in square brackets):

TEMPLVM
[PR]O·SALVTE·DO[MVS]·DIVINA[E]
[EX]·AVCTORITAT[E·TI]·CLAVD·
[CO]GIDVBNI·R[EG·MA]GNI·BRIT·
[COLE]GIVM·FABROR·ET[·Q]VI·IN·E[O]
[SVNT]·D·S·D·DONANTE·APEAM

Which translates as:

To Neptune and Minerva, for the welfare of the Divine Temple, by the authority of Tiberius Claudius Cogidubnus, great king of the Britons, the guild of smiths and those in it gave this temple at their own expense ...ens, son of Pudentinus, presented the forecourt.
