Glastonbury Tor

The origin of the name Glastonbury is unclear, but when the settlement was first recorded in the late 7th and early 8th centuries it was called . Of the latter name, Glestinga is obscure and may derive from an Old English word or Celtic personal name. It may derive from a person or kinship group named Glast. The second half of the name, , is Anglo-Saxon in origin and could refer to either a fortified place such as a burh or, more likely, a monastic enclosure. Tor is often used in the South West of England to refer to a prominent hill deriving from the Old English . The Welsh name of the Tor was , or sometimes , meaning 'Isle of Glass'. At this time the plain was flooded, the isle becoming a peninsula at low tide. ==Location and landscape==

seen through the mist, as viewed from Walton Hill The Tor is almost surrounded by the low-lying Somerset Levels, rising to an elevation of . The Bridport Sands have acted as a caprock, protecting the lower layers from erosion. The iron-rich waters of Chalice Well, a spring at the base of the Tor, flow out as an artesian well impregnating the sandstone around it with iron oxides that have reinforced it to produce the caprock. Iron-rich but oxygen-poor water in the aquifer carries dissolved iron (II) "ferrous" iron, but as the water surfaces and its oxygen content rises, the oxidised iron (III) "ferric" iron drops out as insoluble "rusty" oxides that bind to the surrounding stone, hardening it. The low-lying damp ground can produce a visual effect known as a Fata Morgana when the Tor appears to rise out of the mist. This optical phenomenon occurs because rays of light are strongly bent when they pass through air layers of different temperatures in a steep thermal inversion where an atmospheric duct has formed. The Italian term Fata Morgana is derived from the name of Morgan le Fay, a powerful sorceress in Arthurian legend. Terraces The sides of the Tor have seven deep, roughly symmetrical terraces, or lynchets. Their formation remains a mystery with many possible explanations. They may have been formed as a result of natural differentiation of the layers of Lias stone and clay or used by farmers during the Middle Ages as terraced hills to make ploughing for crops easier. Author Nicholas Mann questions this theory. If agriculture had been the reason for the creation of the terraces, it would be expected that the effort would be concentrated on the south side, where the sunny conditions would provide a good yield, but the terraces are equally deep on the northern side, which would provide little benefit. Additionally, none of the other slopes of the island have been terraced, even though the more sheltered locations would provide a greater return on the labour involved. Other explanations have been suggested for the terraces, including the construction of defensive ramparts. Iron Age hill forts including the nearby Cadbury Castle in Somerset show evidence of extensive fortification of their slopes. The normal form of ramparts is a bank and ditch, but there is no evidence of this arrangement on the Tor. South Cadbury, one of the most extensively fortified places in early Britain, had three concentric rings of banks and ditches supporting an enclosure. By contrast, the Tor has seven rings and very little space on top for the safekeeping of a community. It has been suggested, that a defensive function may have been linked with Ponter's Ball Dyke, a linear earthwork about east of the Tor. The purpose and provenance of the dyke are unclear. It is possible that it was part of a longer defensive barrier associated with New Ditch, three miles to the south-west, which is built in a similar manner. It has been suggested by Ralegh Radford that it is part of a great Celtic sanctuary, probably 3rd century BC, while others, including Philip Rahtz, date it to the post-Roman period and link it to the Dark Age occupation on Glastonbury Tor. The 1970 excavation suggests the 12th century or later. The historian Ronald Hutton also mentions the alternative possibility that the terraces are the remains of a medieval "spiral walkway" created for pilgrims to reach the church on the summit, similar to that at Whitby Abbey. Another suggestion is that the terraces are the remains of a three-dimensional labyrinth, first proposed by Geoffrey Russell in 1968. He states that the classical labyrinth (Caerdroia), a design found all over the Neolithic world, can be easily transposed onto the Tor so that by walking around the terraces a person eventually reaches the top in the same pattern. Evaluating this hypothesis is not easy. A labyrinth would very likely place the terraces in the Neolithic era, but given the amount of occupation since then, there may have been substantial modifications by farmers or monks, and conclusive excavations have not been carried out. In a more recent book, Hutton writes that "the labyrinth does not seem to be an ancient sacred structure". ==History==

Pre-Christian Some Neolithic flint tools recovered from the top of the Tor show that the site has been visited, perhaps with a lasting occupation, since prehistory. The nearby remains of Glastonbury Lake Village were identified at the site in 1892, which confirmed that there was an Iron Age settlement in about 300–200 BC on what was an easily defended island in the fens. There is no evidence of permanent occupation of the Tor, but finds, including Roman pottery, do suggest that it was visited on a regular basis. Excavations on Glastonbury Tor, undertaken by a team led by Philip Rahtz between 1964 and 1966, revealed evidence of Dark Age occupation during the 5th to 7th centuries and a worn hollow bronze head which may have topped a Saxon staff. Christian settlement During the late Saxon and early medieval period, there were at least four buildings on the summit. The base of a stone cross demonstrates Christian use of the site during this period, and it may have been a hermitage. The broken head of a wheel cross dated to the 10th or 11th century was found partway down the hill and may have been the head of the cross that stood on the summit. The head of the cross is now in the Museum of Somerset in Taunton. The earliest timber church, dedicated to St Michael, is believed to have been constructed in the 11th or 12th century; from which post holes have since been identified. Associated monk cells have also been identified. In 1243 Henry III granted a charter for a six-day fair at the site. St Michael's Church was destroyed by an earthquake on 11 September 1275. According to the British Geological Survey, the earthquake was felt in London, Canterbury and Wales, and was reported to have destroyed many houses and churches in England. The intensity of shaking was probably greater than 7 on the Medvedev–Sponheuer–Karnik scale, with its epicentre in the area around Portsmouth or Chichester, South England. After his death in 1936 it was sold to The National Trust which raised money by public subscription for its upkeep. The National Trust took control of the Tor in 1937, but repairs were delayed until after the Second World War. During the 1960s, excavations identified cracks in the rock, suggesting the ground had moved in the past. This, combined with wind erosion, started to expose the footings of the tower, which were repaired with concrete. Erosion caused by the feet of the increasing number of visitors was also a problem and paths were laid to enable them to reach the summit without damaging the terraces. After 2000, enhancements to the access and repairs to the tower, including rebuilding of the parapet, were carried out. These included the replacement of some of the masonry damaged by earlier repairs with new stone from the Hadspen Quarry. '' competition to create a county flag for Somerset. A model vaguely based on Glastonbury Tor (albeit with a tree instead of the tower) was incorporated into the opening ceremony of the 2012 Summer Olympics in London. As the athletes entered the stadium, their flags were displayed on the terraces of the model. ==Mythology and spirituality==

The Tor seems to have been called Ynys Afallon (meaning "The Isle of Avalon") by the Britons and is believed by some, including the 12th and 13th century writer Gerald of Wales, to be the Avalon of Arthurian legend. The Tor has been associated with the name Avalon, and identified with King Arthur, since the alleged discovery of his and Queen Guinevere's neatly labelled coffins in 1191, recounted by Gerald of Wales. Author Christopher L. Hodapp asserts in his book The Templar Code for Dummies that Glastonbury Tor is one of the possible locations of the Holy Grail, because it is close to the monastery that housed the Nanteos Cup. The Tor has been a place of Christian pilgrimage at least since the 11th-century and continues to be so, both because of the long-standing dedication to St. Michael the Archangel (the patron of many sacred mountains and hills) and more recently because of the martyrdoms of the three beatified Benedictine monks on its summit in the 16th-century Abbot Whiting, John Thorne and Roger James. With the 19th-century resurgence of interest in Celtic mythology, the Tor became associated with Gwyn ap Nudd, the first Lord of the Otherworld (Annwn) and later King of the Fairies. The Tor came to be represented as an entrance to Annwn or to Avalon, the land of the fairies. The Tor is supposedly a gateway into "The Land of the Dead (Avalon)". A persistent myth of more recent origin is that of the Glastonbury Zodiac, a purported astrological zodiac of gargantuan proportions said to have been carved into the land along ancient hedgerows and trackways, in which the Tor forms part of the figure representing Aquarius. The theory was first put forward in 1927 by Katherine Maltwood, an artist with interest in the occult, who thought the zodiac was constructed approximately 5,000 years ago. But the vast majority of the land said by Maltwood to be covered by the zodiac was under several feet of water at the proposed time of its construction, and many of the features such as field boundaries and roads are recent. The Tor and other sites in Glastonbury have also been significant in the modern-day Goddess movement, with the flow from the Chalice Well seen as representing menstrual flow and the Tor being seen as either a breast or the whole figure of the Goddess. This has been celebrated with an effigy of the Goddess leading an annual procession up the Tor. It is said that Brigid of Kildare is depicted milking a cow as a stone carving above one of the entrances to the tower. ==See also==
