Minoan craftsmen produced stone vessels at Mochlos from the 3rd millennium BC until the middle of the 2nd millennium. Produced by hand, using a hollow reed as a drill, a wooden bow, and an abrasive like emery to do the actual cutting, a technique originating in Egypt, they were time-consuming projects that required patience and considerable expertise.
The results included several masterpieces of Minoan art.
These stone lids were found in various houses from the island and consist of five green serpentinite lids in addition to two purple limestone and yellowish white tufa examples. Based off the different diameters of the lids, it is likely that they were used for objects ranging from bowls to jars. Also, though these lids were found in Mycenaean deposits, they were produced during earlier eras.
