Greek mythology can be found everywhere but the scholarly writings of the Hellenistic Age.

 "Hellenistic" is distinguished from "Hellenic" in that the latter refers to Greece itself, while the former encompasses all ancient territories under Greek influence, in particular the East after the conquests of Alexander the Great
