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. It is similar to Indian masonry such as the Cyclopean Wall of Rajgir.
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, such as the old city walls of Rajgir.
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:
Modern archaeologists use "Cyclopean" in a more restricted sense than the description by Pausanias; while Pausanias attributes all of the fortifications of Tiryns and Mycenae, including the Lion Gate, to the Cyclopes, only parts of these walls are built in Cyclopean masonry. The accompanying photograph shows the difference between Cyclopean masonry (shown in the blue rectangle), and the ashlar masonry of the Lion Gate.
The entrance of a Mycenaean citadel in the Bronze Age, Lion Gate, demonstrated the monumentalizing occurring in Greece and showed the power of the citadel. Apart from the Tirynthian and Mycenaean walls, other Cyclopean structures include some beehive tombs in Greece and the fortifications of a number of Mycenean sites, most famously at Gla.
In Cyprus, the Kition archaeological site in present-day Larnaca, has revealed cyclopean walls. Additionally, Nitovikla, Enkomi and Maa Paleokastro use Cyclopean masonry.
In Italy, polygonal masonry is particularly indicative of the region of Latium; scholars including Giuseppe Lugli have carried out studies of the technique. Some notable sites that have fortification walls built in this technique include Norba, Signia, Alatri, Boiano, Circeo, Cosa, Alba Fucens, Palestrina,Terracina and Santa Severa. One of the largest and least known is the "acropolis" in Alatri, an hour south of Rome. It also seems to have a portal through which the summer solstice sun shines and some think it is also has a number of other astronomical significant points to it. It is thought to be the second largest in Europe, after Athens. In Sicily, there are many Cyclopean structures especially in Erice, in the western part of the island. The Nuraghe of Bronze Age Sardinia also are described as being constructed in cyclopean masonry, as are some of the constructions of the Talaiot culture abounding on Menorca and present to a lesser extent on Mallorca.
In the ancient city of Rājagṛha (now Rajgir, Bihar, India), cyclopean walls can be seen.
