Submerged beneath sand, sponges and sea grass are the wrecks of thousands of ships. During the past decade three of these ships have been carefully excavated, discovering a fascinating evolution in shipbuilding technology. They date from 300 BC, AD 625 and AD 1000, and lie off the coasts of Greece, Cyprus and Turkey. Archaeologists have discovered exquisite artefacts of glass, bronze and pottery. As a result of meticulous restoration, these artefacts are providing new insights into an ancient world of ships and commerce - a world not dissimilar to our own.
