In the Dunbartonshire OS Name Books, 1860 it reports: “we learn that, in the year 1686, Dr. [Doctor] Irvine observed as follows – At the town of Dumbarton, the remains of a great Roman fort – the vestiges of another at the Castle, half a mile distant – those of a third at the foot of Dumbuck hill, a mile more to the East – of a fourth at Dunglass – and of a fifth on the Chapel Hill, at West Kilpatrick”.

The location has been lost, but if it is half a mile from Dumbarton castle a likely place is the spur of land to the west where some rectangular formal gardens might be a possibility. It is believed the military way extended westwards beyond the fort at Old Kilpatrick and it has been suggested that it may have run to a fort and harbour at Dumbarton. The only physical evidence other that the 1686 reference is a Roman Brass coin of Vespasian, found at Dumbarton, 1858 (Glasgow Courier, 15 May 1858) and a Roman bronze coin of Constantine II said to have been retained by a workman about 1870. For more information see the Canmore entry.

Subdobiadon at position 197 in the Ravenna Cosmography has not been identified. If it were written “SUB-DOBIADON” or perhaps with the merest addition: “SUB-DONBIADON” could it be identified with Dunbardon? If we assume a copy mistake such that R→A and perhaps an omitted ‘n’ then the original form of Dunbarton would be: “SUB-DO_n BIRDON”.
