Psamathus or Psamathous (Ancient Greek: Ψαμαθοῦς), called by Strabo Amathus or Amathous (Ἀμαθοῦς),[1] was a harbour of ancient Laconia. The Periplus of Pseudo-Scylax places it back to back (ἀντίπυλος) with the harbour of Achilleius.[2]
Pausanias places it near Cape Taenarum and Asine, at about 150 stadia from Teuthrone. He says that at the end of Cape Matapan there was a temple in the shape of a cave and a statue of Poseidon.[3] Strabo and other ancient writers call Psamathus a polis (city-state).[1][4][5]
Its site is located near the modern Porto Kagio.[6][7]
