Certisnassa

AttestedCertisnassa at position 255 in the Ravenna Cosmography where it is touring harbour estuaries.

Where:  Mouth of the river Wear, which reaches the sea at Sunderland, around NZ4158.

Name Origin:  Latin certis ‘fixed’ (locative plural of certus) and nassa ‘fish trap’.

NotesFishing weirs in tidal estuaries are a very ancient way of gathering food.  The certis part presumably indicates permanent structures as distinct from lots of lobster pots.  In discussing the Brigstanes Roman sill-dam across river Wear at Hylton, which was probably Dictim, Selkirk (1995:210-4) commented “no doubt the dam was used as a fish-trap [but] why build [there] when there were extensive shallows ... only a few hundred yards away”.  See here for some photos of the Roman stones of the sill-dam, and a discussion of other Roman traces in Sunderland, or here for a newspaper article summarising all evidence for a Roman presence in Sunderland.
