Rich remains from all periods of the Copper and Bronze Age have been found in Cyprus ever since archaeological excavations began there, but hitherto there has been no evidence of a Stone Age. A few implements of stone, some celts and one flint-knife, have been found, but none of them in a Stone Age stratum; those of known provenance are all from the Copper and Bronze Age, and no tombs or other deposits of the Stone Age have been discovered at all. As the Stone Age is represented all round on the mainland, a priori one might be inclined to suppose its existence also in Cyprus, and therefore its non-appearance would be strange in view of the frequent finds of the Copper and Bronze Age.
