Cissum (anc. geog.), a town of the Hither Spain, in Lacetania, on the east side of the Iberus, (thought to be Guifonna.) Where the Carthaginians were first defeated by Scipio. Another Cissa of Thrace, situated on the river Argos Potamus, which Scylax seems to call Creffa, or Criffa; so that the reading is doubtful.
