Tamaris (Tamar)

Port

There are two clues in Ptolemy’s Geography (bk.II, ch.ii); near the the beginning of part 2, which reads:

Description of the south side below which is the Oceanus Britannicus [English Channel]. After the Ocrium Promontorium [Lizard Point, Cornwall] is the mouth of the Cenio¹ river 14*003 51? (then) the mouth of the Tamarus² river 15*40 52? (then) the mouth of the Iscas³ river 17*40 52? …

  1. This river remains unidentified.
  2. River Tamar, Devon/Cornwall.
  3. River Exe, Devon.

and also the very last sentence of part 2:

Next to these [the Durotriges], but more to the west, are the Dumnoni, whose towns are: Voliba 14*45 52? Uxella¹ 15*00 52? Tamara² 15*00 52? (and) Isca, where is located Legio II Augusta³ 17*30 52?.

  1. Vxelis (Launceston, Cornwall); the previous entry Voliba remains unidentified.
  2. At the mouth of the Tamar near Plymouth.
  3. Isca Dvmnoniorvm (Exeter, Devon).

The name Tamaris is mentioned in the Ravenna Cosmology (R&C#5) of the seventh century, where it is listed between the entries for Nemetostatio (Nanstallon, Cornwall) and Dvrnovaria (Dorchester, Dorset).

The river-name Tamar is possibly derived from Welsh?Gaelic, possibly meaning ‘the dark one’ or simply ‘the river’. There are several other British rivers whose names have the same root-meaning; the Thames (Latin Tamesis) in London, the Team in County Durham, the Thame in Buckingham/Oxfordshire, and finally the Tame, of which there are three, in Warwickshire/Staffordshire, Yorkshire/Cheshire and North Yorkshire.

Tamaris must be the mouth of the modern river Tamar’s estuary, near Plymouth.  It has been identified with the ancient trading port of , near Plymouth, but the Roman fort recently identified further upstream on the Tamar, at , seems a more likely location.
