Attested: RC Decha
Where: On the Scottish highland edge, most likely the Roman fort at Stracathro at NO61706575 beside the river North Esk, where it is joined by several tributaries.
Name origin: Probaby a corruption of Latin dextra ‘on the right’, as seen from sea and behind the Roman line of advance.
Notes: RC names in this region need to be identified as a group, with uncertainties discussed here. The North Esk estuary may have been much wider in Roman times because, in addition to the effect of siltation, isostatic rebound after the last Ice Age is making land rise faster than sea levels in much of Scotland. It is one candidate for the Trucculensis Portus ‘savage harbour’ of Tacitus.
