MegalithA megalith is a large stone that has been used to construct a prehistoric structure or monument, either alone or together with other stones. There are over 35,000 in Europe alone, located widely from Sweden to the Mediterranean sea. The word was first used in 1849 by the British antiquarian Algernon Herbert in reference to Stonehenge and derives from the Ancient Greek words "mega" for great and "lithos" for stone. Most extant megaliths were erected between the Neolithic period (although earlier Mesolithic examples are known) through the Chalcolithic period and into the Bronze Age.
ArchaeoastronomyArchaeoastronomy (also spelled archeoastronomy) is the interdisciplinary or multidisciplinary study of how people in the past "have understood the phenomena in the sky, how they used these phenomena and what role the sky played in their cultures". Clive Ruggles argues it is misleading to consider archaeoastronomy to be the study of ancient astronomy, as modern astronomy is a scientific discipline, while archaeoastronomy considers symbolically rich cultural interpretations of phenomena in the sky by other cultures.
PrehistoryPrehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5,000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century.
Brú na BóinneBrú na Bóinne (ˈbɣɾɣuː n̪ɣə ˈbɣoːn̠jə; 'Palace of the Boyne' or more properly 'Valley of the Boyne') or Boyne valley tombs, is an area in County Meath, Ireland, located in a bend of the River Boyne. It contains one of the world's most important prehistoric landscapes dating from the Neolithic period, including the large Megalithic passage graves of Knowth, Newgrange and Dowth as well as some 90 additional monuments. The archaeological culture associated with these sites is called the "Boyne culture".
Megalithic artMegalithic art refers to art either painted or carved onto megaliths in prehistoric Europe. Elizabeth Shee Twohig has coined the term Megalithic art in her study of 'The Megalithic Art of Western Europe'''. Her original definition of Megalithic art focused on paintings or carvings found on the structural elements, like the kerbstones, orthostats, or capstones of megalithic tombs, but recent investigations have included decorations on stelae and menhirs.
CairnA cairn is a man-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word cairn comes from the càrn ˈkhaːrɣn̪ɣ (plural càirn ˈkhaːrɣɲ). Cairns have been and are used for a broad variety of purposes. In prehistory, they were raised as markers, as memorials and as burial monuments (some of which contained chambers). In the modern era, cairns are often raised as landmarks, especially to mark the summits of mountains. Cairns are also used as trail markers.
Stone circleA stone circle is a ring of standing stones. Most are found in Northwestern Europe – especially in Britain, Ireland, and Brittany – and typically date from the Late Neolithic and Early Bronze Age, with most being built from 3000 BC. The best known examples include those at the henge monument at Avebury, the Rollright Stones, and elements within the ring of standing stones at Stonehenge. Scattered examples exist from other parts of Europe. Later, during the Iron Age, stone circles were built in southern Scandinavia.
HengeThere are three related types of Neolithic earthwork that are all sometimes loosely called henges. The essential characteristic of all three is that they feature a ring-shaped bank and ditch, with the ditch inside the bank. Because the internal ditches would have served defensive purposes poorly, henges are not considered to have been defensive constructions (cf. circular rampart). The three henge types are as follows, with the figure in brackets being the approximate diameter of the central flat area: Henge (> ).
Megalithic architectural elementsThis article describes several characteristic architectural elements typical of European megalithic (Stone Age) structures. In archaeology, a forecourt is the name given to the area in front of certain types of chamber tomb. Forecourts were probably the venue for ritual practices connected with the burial and commemoration of the dead in the past societies that built these types of tombs. In European megalithic architecture, forecourts are curved in plan with the entrance to the tomb at the apex of the open semicircle enclosure that the forecourt creates.
PetroglyphA petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs, estimated to be 20,000 years old are classified as protected monuments and have been added to the tentative list of UNESCO's World Heritage Sites. Petroglyphs are found worldwide, and are often associated with prehistoric peoples.
