Megalithic Age Definition
As with the northern megaliths, the southern examples contain few, if any, artifacts. However, a small number of megalithic burials contain fine polished red pottery, bronze daggers, polished foundation stone daggers, and green stone ornaments. Southern megalithic burials are often found in groups distributed in lines parallel to the direction of rivers. Megalithic cemeteries contain burials connected by low stone platforms made of large river cobblestones. The broken polished red pottery and charred wood found on these platforms have led archaeologists to hypothesize that this platform was sometimes used for ceremonies and rituals.  The capstones of many southern megaliths have carvings of «cutting markers.» A small number of capstones have human depictions and daggers. 9000 BC J.-C. Chr.: Work begins on round megalithic buildings in Gobekli Tepe, Turkey. 8000: The first known works (post holes) begin at Stonehenge. See Mesolithic art. In conjunction with megalithic constructions throughout Europe, there are often large earthworks of various designs – ditches and banks (such as the Dorset Cursus), wide terraces, circular enclosures known as henge, and often artificial mounds such as Silbury Hill in England and Monte d`Accoddi in Sardinia (the prehistoric step pyramid).
Other examples of megalithic architecture include: the taula, a straight stone topped by another to form a «T» shape; and the trilithon, consisting of two parallel menhirs crowned with a horizontal stone (lintel). (Stonehenge) It appears in later megalithic tombs and stone vaults or underground boxes. The megalithic monuments are of very diverse composition. Their names often (but not always) reflect much of their complexes, but archaeological evidence at many sites continues to reveal previously unknown complexities. Below is a list of elements identified on megalithic monuments. Some non-European examples were also used for comparison purposes. The less ancient megalithic tombs in the «southern» style – found mainly on the Korean peninsula and numbering as many as 100,000 – date from the latter part of early Mumun (c. 850-700 BC) or the Middle Mumunun period (c.
700-550 BC). Smaller than the northern tombs, their burial chamber is underground and usually lined with stone slabs. A huge capstone acts as a roof and is usually supported by smaller supporting stones. Like their «northern» counterparts, most southern-style megalithic tombs contain few artifacts, although some excavations have unearthed caches of ancient pottery, bronze weapons, and green stone ornaments, while a number of capstones are decorated with relief carvings, sculptures, and other types of engravings. In the middle of the 2nd millennium AD, the megalithic funerary monuments of Madagascar were erected in the middle of the emerging period of the Merina Kingdom.  Some megaliths are used by Malagasy speakers for funerary practices (e.g., ceremonies of the overthrow of the dead) in modern times.  Other examples of megalithic tombs include the cairn at Midhowe on Orkney and the passing tomb at Bryn Celli Ddu on Anglesey. Also in Louisenlund and Gryet on the Danish island of Bornholm, there are vast tombs with up to 60 megaliths.  They are widespread in Europe, Africa and Asia, but they are more numerous in Western Europe; especially in Ireland, Great Britain and Brittany, where there are about 50,000 copies, and in northwestern France, where there are about 1,200 other copies.  Standing stones are generally difficult to date.
They were built in many different periods of prehistory as part of the wider megalithic cultures in Europe and surrounding regions. The oldest structures in Göbekli Tepe are about 7,000 years older than the megaliths in Stonehenge, although it is doubtful that any of the European megalithic traditions (see below) were derived from them.  The menhir has a very ancient tradition in the Middle East, dating back to Mesopotamian times. Although they are not always «megalithic» in the strict sense, they are found throughout the region and in some cases can reach 5 meters or more (for example in Ader in Jordan). This phenomenon can also be traced through many passages in the Old Testament, such as those referring to Abraham`s grandson Jacob pouring oil on a stone he erected after his famous dream of angels ascending to heaven (Genesis 28:10-22). Jacob is also described as erecting stones on other occasions while Moses erected twelve pillars symbolizing the tribes of Israel. The tradition of venerating menhirs continued into Nabataean times. Related phenomena such as cutting holes, rock tombs and circles also occur in the Middle East. Another well-known form of megalithic monument is the menhir (along the Breton words «man`s stone» and «hir»), a single vertical stone, often of enormous size, used alone or in conjunction with a tomb. Menhirs were often arranged in circles (cycoliths) (see, for example, Stonehenge, Avebury and Brodgar`s Ring), semicircles, large-scale ellipses or parallel rows called alignments (see the approximately 3000 menhirs in Carnac, Brittany, France). In general, megalithic menhirs and stone circles are younger than older tombs. Ceremonial complexes with large pre-ceramic Neolithic T-shaped megalithic orthostats (PPN, ca.
9600-7000 cal BC) have been discovered at a number of sites in southeastern Turkey. Much research on history has shown that the peoples of the Stone Age moved large stones on cylindrical wooden scrolls. However, there is some disagreement with this theory, especially since experiments have shown that this method is impractical on uneven ground. In some contemporary megalithic building cultures, such as Sumba, Indonesia, emphasis is placed on the social status of moving heavy stones without the relief of the scrolls. In most documented contemporary megalithic building communities, stones were placed on wooden sledges and pulled without rollers.  Nabta Playa at the southwest corner of the Western Egyptian Desert was once a large lake in the Nubia Desert, 500 miles south of present-day Cairo.  By the 5th millennium BC, the peoples of Nabta Playa had developed an astronomical device that accurately marks the summer solstice.  The results suggest that the area was populated only seasonally, probably only in the summer, when the local lake filled with water for cattle grazing.  There are other megalithic stone circles in the southwestern desert. The megalithic traditions of Northeast Asia originated in Gojoseon, which was located in present-day Manchuria and North Korea. This was particularly pronounced in the early phases in the Liao River basin.
  The practice of erecting megalithic burials spread rapidly from the Liao River basin to the Korean peninsula, where the structure of megaliths varies geographically and chronologically. Early megalithic burials are called «north» or «table style» because they feature a burial chamber above the ground made of heavy stone slabs forming a rectangular box.  An oversized capstone is placed on the burial chamber of the stone slab, creating the appearance of a table.
