Secor

Dictionary of Greek and Roman Geography

SECOR or SICOR(Σηκὼρ ἢ Σικόρ λιμήν), a port which Ptolemy (Ptol. 2.7.2) places on the west coast of Gallia, between the Pectonium or Pictonium Promontorium and the mouth of the Ligeris ( Loire). The name also occurs in Marcianus. The latitudes of Ptolemy cannot be trusted, and we have no other means of fixing the place except by a guess. Accordingly D'Anville supposes that Secor may be the port of the Sables d'Olonne;and other conjectures have been made.
