Hecataeus of Abdera also refers to a holy island, sacred to the Pelasgian (and later, Greek) Apollo, situated in the westernmost part of the "Okeanós Potamós", and called in different times Leuke or Leukos, Alba, Fidonisi or Isle of Snakes. It was on Leuke, in one version of his legend, that the hero Achilles, in a hilly tumulus, was buried (which is erroneously connected to the modern town of Kiliya, at the Danube delta). "Accion" ("ocean"), in the fourth century AD Gaulish Latin of Avienus' "Ora maritima", was applied to great lakes.
