in Britain, mentioned in the ninth Itinerary as the second station from Venta Icenorum (Norwich
), the first being Sitomagus. Horsley places Comn-breton-ium at the confluence of the rivers Breton
and Stour, relying upon the similarity of name.
This places it near Strat-ford,
a locality with a Roman name. Others have identified Stratford
with Ad ansam, the next station to Combretonium. Horsley's view seems the safer.
