The second century geography of Claudius Ptolemaeus records that the Uxella Aestuarium lies somewhere along the southern shores of the Severn Estuary (at coordinates 16*00 53°30), and this name has been associated with the River Axe in Somerset. A later entry in Ptolemy (vide supra) records a town named Iscalis, whose given coordinates (16*00 53°40) place it very near the mouth of the Axe, indeed, the name may stem from the same Welsh/Gaelic root, usk, axe, uisg, exe, isc & c. all meaning 'water'. The name Iscalis possibly means something like 'the settlement by the water'.
"Below the Dobuni are the Belgae¹ and the towns:
Iscalis 16*00 53°40, Aquae Calidae 17*20 53°40 and Venta 18*40 53°00.²"
There are two substantial Roman buildings at Bawdrip, one on the north-western outskirts of the village (ST3240) and another a little along the road to the south-east (ST3539). There is also a salt working site at Huntspill (ST3743) about three miles to the north-east.
It is possible that the road from Ilchester continued north-west towards the Bristol Channel near Burnham-on-Sea, where there are known Roman buildings nearby at Lakehouse Farm (ST3550), and a Romano British temple at Brean Down (ST2958) overlooking the Channel near Weston-super-Mare, both sites in Somerset.
