The Roman Map of Britain River Wear, Durham

Antrum (R&C 257) next
Ouedra Vedra (Ptolemy II 3 4)

    Ravenna's entry -ntrum is for Uirum Wear, between the Trent (R&C 256) and the Tyne (R&C 258). Bede has Wiri, Uuiuri (gen.). See ERN 441 sub Wear for a consideration of two competing forms. It is also possible that Ouedra is an error for Oueora or similar.
