Ceryneia or Keryneia (Ancient Greek: Κερύνεια, also Cerynia or Kerynia (Κερυνία), Ceraunia or Keraunia (Κεραυνία), Cerauneia or Kerauneia (Κεραύνεια), Caryneia or Karyneia (Καρύνεια), was a town and polis (city-state)[1] of ancient Achaea.
Its population was increased by a large body of Mycenaeans, when the latter abandoned their city to the Argives in 468 BCE.
It was situated inland upon a lofty height, west of the river Cerynites (Bokhusia), and a little south of Helice.
[6] The place is celebrated in Greek mythology as the location of the Ceryneian Hind, the capture of which was one of the Labours of Hercules.
Its ruins have been discovered on the height, which rises above the right bank of the Cerynites, just where it issues from the mountains into the plain, near modern Mamousia.
