Attested:  RC Duriarno

Where:  Probably the Roman fort at Nanstallon, SX03436700, near Bodmin, commanding the portage across Cornwall from the river Camel to the river Fowey.

Name originDuro ‘crossing’ plus a river name *arno, a common name across Europe probably related to Sanskrit arna ‘river’.

Notes:  AI’s Ernodurum (modern Saint-Ambroix on the river Arnon in France) is essentially the same name.  Other similarly named rivers include the Arno in Italy, Arnon in Jordan, and Erne in Ireland.  The name change to Camel probably originated with the notorious pseudo-historian Geoffrey of Monmouth. RC’s Sarna probably lay at its estuary mouth, and Boscarne is opposite Nanstallon.
