Cyclopean masonry

Cyclopean masonry is a type of stonework found in Mycenaean architecture, built with massive limestone boulders, roughly fitted together with minimal clearance between adjacent stones and with clay mortar or no use of mortar. The boulders typically seem unworked, but some may have been worked roughly with a hammer and the gaps between boulders filled in with smaller chunks of limestone.

The most famous examples of Cyclopean masonry are found in the walls of Mycenae and Tiryns, and the style is characteristic of Mycenaean fortifications. Similar styles of stonework are found in other cultures and the term has come to be used to describe typical stonework of this sort.

The term comes from the belief of classical Greeks that only the mythical Cyclopes had the strength to move the enormous boulders that made up the walls of Mycenae and Tiryns. Pliny's Natural History reported the tradition, attributed to Aristotle, that the Cyclopes were the inventors of masonry towers, giving rise to the designation "Cyclopean".

The walls are usually founded in extremely shallow beddings carved out of the bedrock. "Cyclopean", the term normally applied to the masonry style characteristic of Mycenaean fortification systems, describes walls built of huge, unworked limestone boulders which are roughly fitted together. Between these boulders, smaller chunks of limestone fill the interstices. The exterior faces of the large boulders may be roughly hammer-dressed, but the boulders themselves are never carefully cut blocks. Very large boulders are typical of the Mycenaean walls at Mycenae, Tiryns, Argos, Krisa (in Phocis), and the Acropolis of Athens. Somewhat smaller boulders occur in the walls of Midea, whereas large limestone slabs are characteristic of the walls at Gla. Cut stone masonry is used only in and around gateways, conglomerate at Mycenae and Tiryns and perhaps both conglomerate and limestone at Argos.

Harry Thurston Peck, writing in 1898, divided Cyclopean masonry into four categories or styles:

While Peck's first and possibly second and third styles conform to what archaeologists today would classify as cyclopean, the fourth now is referred to as ashlar and is not considered cyclopean. There is a more detailed description of the Cyclopean styles at the Perseus Project.

Pausanias described the Cyclopean walls of Mycenae and Tiryns:

There still remain, however, parts of the city wall [of Mycenae], including the gate, upon which stand lions. These, too, are said to be the work of the Cyclopes, who made for Proetus the wall at Tiryns. (2.16.5) Going on from here and turning to the right, you come to the ruins of Tiryns. ... The wall, which is the only part of the ruins still remaining, is a work of the Cyclopes made of unwrought stones, each stone being so big that a pair of mules could not move the smallest from its place to the slightest degree. Long ago small stones were so inserted that each of them binds the large blocks firmly together.(2.25.8)
