Sudbrook, Monmouthshire the Silures from the 2nd century BC and occupied by the Romans from the 1st century AD until the 4th century. The hillfort was originally much bigger than now having been eroded over the centuries. Finds of Roman coins at Black Rock, Portskewett, show that the ferry crossing was in use in Roman times, on the route between the Roman stations of "Aquae Sulis" (Bath) and "Venta Silurum" (Caerwent). According to tradition, Caradog Freichfras, the Welsh ruler of Gwent in the 5th century or 6th century AD, moved his court from Caerwent to the Portskewett area, possibly to the fort.
Aquae Sulis cuamiun ai" "The affixed – Deuina, Deieda, Andagin, (and) Uindiorix – I have bound" An alternative translation based on a much better knowledge of the Celtic languages is the following: "May I, Windiorix for/at Cuamena defeat (alt. "summon to justice") the worthless woman, oh divine Deieda." (Alt. "Divine Deiada, may I, Windiorix, bring to justice/defeat (in court) the woman at Cuamena".) This is a superior, though still uncertain, translation in that it takes into account the nominal cases of the nouns: "Windiorix" (alt. "Windorix") - nominative masculine (subject), lit. "fair-headed" ("windo") "king" ("rix"); "Dewina Deieda" - nominative/vocative feminine "divine Deieda"
