What became of the ports of call visited by the Cretan rulers of the waves? From where did Mycenaean ships set sail for Colchis and Troy? It was questions such as these that encouraged N. Flemming , explorer of sunken cities, to go to work with the archaeologist Dick Simpson and professor Chuck Higgins. Starting from the information in Pausanias that Elafonisos was a peninsular in antiquity, an underwater exploration was organized by a team from Cambridge University and the British School of Archaeology. Ruins of the greatest Mycenaean settlement ever found till now were brought to light. 37 cist graves were also discovered, enclosed with slabs of stone. These tombs belong to the Middle Helladic period (1900-1600 BC).
