Mysteries of Stonehenge…

Stonehenge…
Why was it built? Does anyone really know?...
4 слайд
The most famous prehistoric monument in the world, and now a world heritage site, Stonehenge stands alone in the vast empty tract of Salisbury plain. Its origins date back nearly 5,000 years and it has been home to pagan religion and spiritual worship, not to be mention public debate ever since. What was this vast collection of stones intended for? Was it observatory of the moon, a temple to the sun, or an elaborate cemetery? Who were the people who carried and carved these 40 ton rocks?
5 слайд
The Stonehenge is a formation of stones in a circular fashion that are standing upright. The construction of this prehistoric monument started some 5000 years ago and it is amazing to know that these stones are still in place after 5 millenniums.
6 слайд
The circle, 320 feet in diameter, had a single entrance, 56 mysterious holes around its perimeter (with remains in them of human cremations), and a wooden sanctuary in the middle. The circle was aligned with the midsummer sunrise, the midwinter sunset, and the most southerly rising and northerly setting of the moon.
7 слайд
The standing stones in the centre consist of two main kinds of rock. The larger blocks and their lintels are all of sarsen, a natural sandstone which occurs as huge boulders on the surface of the Marlborough Downs about 30km (20 miles) to the north of Stonehenge. The smaller stones, known as the Bluestones from their color, are of several kinds of rock which come from the Preseli Mountain in south-west Wales, about 385km (240 miles) away.
8 слайд
The Sarsen Circle, about 30m (100ft) in diameter, consisted originally of 30 uprights, each weighing about 25 tonnes, capped by a continuous ring of 30 lintels weighing about 7 tonnes. Inside it was a horseshoe of five Sarsen Trilithons each consisting of a pair of huge uprights, weighing up to 45 tonnes, capped by a massive lintel.
9 слайд
The Bluestone Circle, now much ruined and incomplete, stands inside the sarsen circle. Originally it consisted of about 60 stones set close together. Only two of the surviving stones have been dressed to shape, and both of these had formerly been used as lintels.
10 слайд
Apart from the Heel Stone and Station Stones, all the sarsens have been dressed to shape by pounding their surfaces with stone hammers. The uprights are slightly 'dished' on the top to provide a secure seating for the lintels, and tenons have been left projecting from them to fit into corresponding hollow mortice-holes in the undersides of the lintels. In addition, the lintels of the outer circle are fitted to each other with vertical tongue-and- groove joints.
11 слайд
The Bluestone Horseshoe, standing inside which alternate round the horseshoe. Two of them bear traces on their tops of projecting tenons, which have been almost battered away. Another has a dished top, like the sarsen uprights, and the adjacent pillar has a groove worked all the way down one side. This stone must once have fitted against another with a corresponding ridge, which now survives only as a stump below the surface on the opposite side of the horseshoe.
12 слайд
As in many later cathedrals and churches, not all the structures that we see today at Stonehenge were built at the same time. As the result of excavations we can now divide the history of Stonehenge into several periods, covering a span of about fifteen centuries between about 3050 and 1600BC.
13 слайд
THE FIRST PHASE of Stonehenge was a circular earthwork, similar in appearance to a Neolithic causewayed enclosure. It may have served as a ceremonial tribal meeting place, but its alignment also suggests a relationship with the midsummer sunrise.The earliest structures were the circular ditch and bank, which survive today, dating from about 3050BC. Within the bank, the ring of the Aubrey Holes was dug. These were round pits in the chalk, averaging one metre wide and deep, with steep sides and flat bottoms, forming a cirqle 86.6m (284ft) in diameter. Initially they held timber posts, but were later left unused except for cremation burials.
THE SECOND PHASE of Stonehenge lasted three centuries between 2900BC and 2600BC. Archaeological evidence shows that timber settings were added to the interior of the earthwork 'henge', although the design, form and extent of these cannot be affirmed
14 слайд
THE THIRD AND FINAL PHASE of Stonehenge saw the arrival of stones, transported over long distances.
It began with the bluestones in about 2600BC. Bluestones from Preseli Mountain in Wales, weighing up to 4 tonnes apiece, were set up to form a double crescent in the centre of the earthwork. Their excavated sockets are referred to as the Q & R holes. Whether the setting was intended to be circular.
15 слайд
16 слайд
The principal entrance in the north-east was marked by three Portal Stones. Today only one, the fallen Slaughter Stone, remains. Outside the entrance was set the Heel Stone, also a second stone, marking the alignment with the midsummer sunrise.
17 слайд
PERHAPS TWO OR THREE HUNDRED YEARS after the arrival of the bluestones, the construction of the sarsen stone circle was begun. It was to become one of the greatest achievements of prehistory.
18 слайд
The final phase of Stonehenge extended another 700 years until about 1600BC. Archaeological evidence during this period shows no change in the arrangement of the sarsen circle and horseshoe, but, for reasons unknown, the bluestones were rearranged at least three times. They may have imitated the sarsen settings, and were also arranged in the form of a circle and an oval. Then, in their final setting, they were changed to a circle and a horseshoe. In about 1700BC a double circle of the Y and Z Holes was dug around the outside of the sarsen circle, with possibly the intention of rearranging the bluestones yet again. For reasons unknown, the work remained unfinished.
19 слайд
20 слайд
All the stones are said to be placed perfectly with the sunrise and thus makes it very clear that the place was also being used as a ground for worship
21 слайд
22 слайд
23 слайд
Professors Darvill and Wainwright believe that Stonehenge was a centre of healing - a "Neolithic Lourdes", to which the sick and injured travelled from far and wide, to be healed by the powers of the bluestones.
They note that "an abnormal number" of the corpses found in tombs nearby Stonehenge display signs of serious physical injury and disease.
24 слайд
25 слайд
For many thousands of years, up to about 4000BC, the people living in southern Britain consisted of scattered bands of roving hunters living on game, fish from the rivers and wild plants. They grew no crops and had no domesticated animals. For tools and weapons they used flint, bone and deer antler, and for shelter they built huts or wind-breaks of brushwood at their temporary camp-sites, and perhaps used skin tents as well.
26 слайд
Their clothes were of leather (like the suede used today), although evidence of weaving suggests that cloth was worn as well. Hide was probably used for some of their domestic utensils, though excavations elsewhere suggest most would have been of wood. Small implements were of antler and bone. Their baggy round-bottomed pots look like imitations in clay of the leather vessels. They buried their important dead in specially constructed narrow mounds called long barrows.
27 слайд
Many researchers have argued, who more convincingly than others, that Stonehenge was a site of religious rites of its time. There are several good reasons behind this assumption, but unfortunately it only takes one aspect of the theory that cannot be proven to collapse the whole train of thought.
28 слайд
The facts tying Stonehenge to astronomy aren’t foolproof, but some at least very interesting points have been made in several studies of this topic.
29 слайд
30 слайд
31 слайд
With the astronomical connection, it didn’t require an enormous leap of imagination to think that Stonehenge was used to also predicting events of the night sky. Hawkins and Hoyle developed their own methods to predict lunar eclipses with the construction of Stonehenge, which consisted of record-keeping with the help of the Aubrey Holes and movable marker stones or wooden logs. These theories are quite accurate, and the only flaw with them is the fact that they require rather high degree of astronomical and mathematical knowledge, in conjunction with records covering at least nearly twenty years. These records would have had to be passed without written records (since we assume there are none, because we haven't found any), and a society of high mathematical and astronomical skills without the wisdom of writing… well, let’s just say that it doesn’t add up properly.
32 слайд
33 слайд
34 слайд
But Stonehenge isn’t ‘alone’. There is an amazing and fascinating monument called Dolmens in our country. Like Stonehenge it’s full of legends and myths about its creation, using and history.
35 слайд
It is very difficult now to restore the rituals connected with the dolmens. Different dolmens are believed to have power in different areas, such as health, love, and family. People leave offerings at the appropriate dolmen to get help in each of the different areas of their lives.
The location of dolmens shows that they are occupying the even parts on the slopes of the hills, river terraces and not high mountains (maximum height up till 500-700 meters over the sea level). Only some single dolmens are located on the heights.
36 слайд
37 слайд
38 слайд
39 слайд
40 слайд
41 слайд
The person buried in the dolmen was the medium between the world of the living and the gods. The dead were left in front of dolmen or were buried in the ground. After rotting, the bones and skull were put inside the dolmen. Later in time, the cult of the dead changed and the fear of the dead appeared. It is the time when the false-portal type of dolmens appeared.
In order to stop the dead finding their way back in the world of the living, a convexity on a facade was made to simulate a stone plug, but the true hole is cut on the back side - on the north side of the dolmen, which was associated with the world of the dead. Sometimes it would be covered with soil, as it is the entrance to the underworld.

44 слайд
While generally unknown in the rest of Europe, these Russian megaliths are equal to the great megaliths of Europe in terms of age and quality of architecture, but are still of an unknown origin. In spite of the variety of Caucasian monuments, they show strong similarities with megaliths from different parts of Europe and Asia, like the Iberian Peninsula, France, Great Britain, Ireland, Netherlands, Germany, Denmark, Sweden, Israel and India. A range of hypotheses has been put forward to explain these similarities and the building of megaliths on the whole, but still it remains unclear.

50 слайд
Until 1918, when it was given to the nation, Stonehenge was in private hands. Since that date about half of the site has been excavated at various times, and a number of the leaning and fallen stones have been straightened and re- erected. In recent years the number of visitors has become so large (700,000 in a year) that the surface of the monument, right out to the surrounding bank and ditch, has been dangerously eroded, and many of the fallen stones, and the stumps which protrude above the surface, are being ground away by the feet of those who step or climb on them. It has thus become necessary to prevent further erosion by restricting public access to the interior of the site. Only in this way can this unique structure be preserved for the future.
51 слайд
But no place has generated so much speculation and wild theories as the standing stones of Stonehenge. After driving for miles through the rolling hills and plains of the English countryside the sight of this unusual structure makes people gasp. A walk around it only provokes more strange feelings. There's a sense that this is something very important. It taunts us with it's mystery. For over 5000 years it has stood silent vigil over the earth. It has been excavated, x-rayed, measured, and surveyed. Yet despite all that has been learned about its age and construction, its purpose still remains one of the great mysteries of the world…
52 слайд
53 слайд
54 слайд
Three hundred years ago the antiquary John Aubrey first suggested that stone circles were Druidical temples, and ever since it has been popularly believed that Stonehenge was built and used by the Druids. This belief is certainly false. Everything that we know about the Druids was recorded by classical writers like Julius Caesar, who tell us that they were a Celtic priesthood who flourished in Britain at the time of the Roman conquest, and perhaps for a few centuries before. By then the stones of Stonehenge had been standing for two thousand years, and were probably already in ruins. Moreover, these accounts make it clear that the Druids built no temples of their own, but held their ceremonies in clearings in the forest.
55 слайд
56 слайд
57 слайд
Modern work studies suggest that even if all 600 people had been continuously employed over the complete route, the task would have taken more than a year to complete.
58 слайд
59 слайд
The method probably used to erect the stones is shown below. A foundation pit was dug in the chalk, with one side vertical and the opposite one of the form of a sloping ramp. A row of wooden stakes was driven in against the vertical side to stop the chalk being crushed down by the toe of the stone as it was raised. The stone, base foremost, was then moved on rollers towards the ramp, until its toe was over the hole and its centre of gravity avas just behind the leading roller. The outer end was then levered up, dipping the base into the hole, until the stone over-balanced at the next moment and came to rest in a leaning'position. Next, with levers supported by timber packing, it was raised a few inches at a time and held in place by struts when the packing had to be rebuilt closer to the stone. Finally it would be pulled upright by gangs of men hauling on ropes. To raise a stone of the outer circle of sarsens would need about 200 people.
60 слайд
The method probably used to raise the lintels is shown above. First the lintel is positioned on the ground, close and parallel to the base of the uprights, and each end alternately is lifted with levers and supported on temporary packing of squared timber. Then a 'crib' of criss-crossed timbers is built around the lintel and uprights, and decked over with stout planks just beneath the underside of the lintel. Now the weight of the stone is transferred with levers from the old packing resting on the ground to new packing resting on the deck. Thereafter the whole process is repeated in stages, the lintel being raised about 60cm (2ft) at each stage. Finally when the uppermost deck was level with the tops of the uprights the lintel is levered sideways to fit over the projecting tenons. Once it was in place the crib would have been dismantled for re-use. Lifting in this way has been used by modern engineers in places abroad where no machines were available.
61 слайд
To help in adjusting the stones to a vertical position, their bases were dressed to a blunt point on which the mass could more easily pivot. When the final adjustment had been made, the hole round the base was rapidly packed with stones, including discarded hammers, and with chalk rammed hard.
62 слайд
If there is one to be made, it is that we don’t know much anything, which is exactly as much as we did know before. Whereas it’s disputable to claim that Stonehenge was used to predict or even observe astronomical events, it is quite obvious that those Neolithic people who started to build Stonehenge did place a great importance to their gods – mainly the Sun and the Moon and if the megalith in the middle of Salisbury Plains wasn’t exactly built for skyworship, it was probably built with certain amount of honoring to the unknown.
