Attested: RC Adron
Where: Adron occurs in RC's harbour-estuary tour, when it has reached Hadrian's Wall. It probably referred to the river Tyne, crossed by a bridge at Newcastle-upon-Tyne, which is generally assumed to be Pons Aelii in ND, where Aelius was Hadrian's family name.
Name origin: The origin of the name Hadrian is uncertain, possibly from Adria, a port near the mouth of the river Po, south of Venice, which Pokorny (1959, p3) attributed to a PIE root *ad-ro- ‘water current’. Adron, as written, matches Greek ἁδρος ‘thick, well-grown’.
Notes: The closest parallel is the river Adrana, mentioned by Tacitus, now the Eder in Germany.
