__NOTOC__ Aboriginal stone arrangements are a form of rock art constructed by Indigenous Australians. Typically, they consist of stones, each of which may be about 30 cm in size, laid out in a pattern extending over several metres or tens of metres. Notable examples have been made by many different Australian Aboriginal cultures, and in many case are thought to be associated with spiritual ceremonies. Particularly fine examples are in Victoria, where the stones can be very large (up to 1 metre high). For example, the stone arrangement at Wurdi Youang consists of about 100 stones arranged in an egg-shaped oval about 50m across. Each stone is well-embedded into the soil, and many have "trigger-stones' to support them. The appearance of the site is very similar to that of the megalithic stone circles found throughout Britain (although the function and culture are presumably completely different). Although its association with Indigenous Australians is well-authenticated and beyond doubt, the purpose is unclear, although it may have a connection with initiation rites. It has also been suggested that the site may have been used for astronomical purposes (Morieson 2003). Other well-known examples in Victoria include the stone arrangements at Carisbrook and Lake Bolac.〔Long, A. & Schell, P., 1999, Lake Bolac stone arrangement (AAV 7422-394); management plan. An unpublished report to Aboriginal Affairs Victoria.〕 Australia's largest collection of standing stones is said to be at Murujuga, also known as the Burrup peninsula or the Dampier archipelago, in Western Australia, which includes tall standing stones similar to the European menhirs, as well as circular stone arrangements. A very different example is found near Yirrkala in Arnhem Land, where there are detailed images of the praus used by Macassan fisherman fishing for Trepang, several hundred years before European contact. Here the stones are small (typically 10–20 cm), sit on the surface of the ground, and can easily be moved by hand, which also implies that they can be easily damaged or altered by modern hands, so that caution is needed when interpreting such sites. Similar examples are found scattered throughout Australia, mainly in remote or inaccessible places, and it is likely that there were many more prior to European settlement of Australia. In South East Australia are found Bora rings which consist of two circles of stones, one larger than the other, which were used in an initiation ceremony and rite of passage in which boys were transformed into men. Some Aboriginal stone arrangements in south-east Australia are aligned to cardinal directions with an accuracy of a few degrees 〔Orientations of linear stone arrangements in New South Wales (Hamacher et al., 2013, Australian Archaeology, 75, 46-54 )〕 while the Wurdi Youang stone arrangement, which indicates the direction of solstitial sunsets, appears to have been built around the east-west direction, again with an accuracy of a few degrees.〔Wurdi Youang: An Australian Aboriginal Stone Circle with possible solar indications (Norris et al., 2013, Rock Art Research, 30, 55-65. )〕 This requirement for highly accurate direction is also indicated by the practice of orienting the graves of deceased Kamilaroi men to an accuracy of a few degrees〔Further Notes on the Australian Class Systems (A. W. Howitt and Lorimer Fison, 1889, J. Anthropol. Inst. of Great Britain and Ireland, 18, 31-70 )〕 ==See also== * Indigenous Australian art * Aboriginal Astronomy * Archaeoastronomy 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aboriginal stone arrangement」の詳細全文を読む スポンサード リンク
