Attested: Ptolemy 2,3,28 Ισκαλις (or Ισχαλις), a πολις of the Βελγαι tribe.
Where: This name has been generally been identified with the Roman fort at Charterhouse, Somerset, ST50405578, the centre of a major lead (and silver) mining industry, whose archaeology was discussed by Todd (1996). Alternatively this entry might result from a manuscript error (small, but affecting name, coordinates, and tribe) on an entry that originally referred to Isca of the 2nd legion (Caerleon).
Name origin: See Isca, possibly derived from ισχυς ‘power, the main body of troops’. The –alis ending is a banal Latin adjective-forming suffix.
