Stymphalus

Stymphalus was a town of northeastern Arcadia, in the central Peloponnese, set by a lake famous in myth for the Stymphalian birds slain by Heracles. The military writer Aeneas Tacticus, author of a surviving treatise on withstanding siege, is traditionally identified with Aeneas of Stymphalus, an Arcadian general of the mid-fourth century BC.
