Secor

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.
