Beautiful Kalamos, Greece

Delphinium or Delphinion (Ancient Greek: Δελφίνιον) was a town of ancient Boeotia or of ancient Attica, the port-town of Oropus. Strabo, calls the harbour "sacred" and says it was opposite ancient Eretria in Euboea at a distance of 60 stadia; he places it at the beginning of Boeotia, 20 stadia from Oropus.
