The beautiful varieties of porphyry - green, red, striped - which are obtained, often in big monoliths, near Kolyvan, are cut at the imperial stone-cutting factory into vases and other ornaments, familiar in the art galleries and palaces of Europe.
Moreover, the narrow passages between the eastern monoliths had become worn by use into hollows which threatened their foundations.
The " megalithic " monuments of Agia Phaneromeni 1 and Hala Sultan Teke near Larnaca may perhaps be early, like the Palestinian cromlechs; but the vaulted chamber of Agia Katrina near Enkomi seems to be Mycenaean or later; and the perforated monoliths at Ktima seem to belong to oil presses of uncertain but probably not prehistoric date.
The splendid alignment of monoliths at Gezer is described in detail in P.E.F.
The highly finished monoliths are all representations of a many-storeyed castle, with an altar at the base of each.
