In some places you can see ancient amphora littering the seabed, in others long submerged cities sleeping beneath the waves.
The oldest known pieces are imitations of the Athenian mintage of the 4th century B.C., with the legend AOE and the owl standing on an overturned amphora.
One contained an amphora full of reclaimed mosaic pieces, presumably for use by the town's building trade.
In the foreground is a broken amphora, in the process of being excavated in a house just outside the citadel walls.
This involves the excavation, detailed recording and analysis of neonate remains from large amphora dating to 600BC.
