2.2 Pointers to eternity
A structural innovation to break the limitation of the Roman arch was a new form of the arch based not on the circle, but on the oval. This does not seem a great change, and yet its effect on the articulation of buildings is spectacular. Of course, a pointed arch is higher, and therefore opens more space and light. But, much more radically, the thrust of the Gothic arch makes it possible to hold the space in a new way, as at Rheims. The load is taken off the walls, which can therefore be pierced with glass, and the total effect is to hang the building like a cage from, the arched roof. The inside of the building is open, because the skeleton is outside. John Ruskin describes the effect of the Gothic arch admirably.
Egyptian and Greek buildings stand, for the most part, by their own weight and mass, one stone passively incumbent on another; but in the Gothic vaults and traceries there is a stiffness analogous to that of the bones of a limb, or fibres of a tree; an elastic tension and communication of force from part to part, and also a studious expression of this throughout every visible line of the building.
Of all the monuments to human effrontery, there is none to match these towers of tracery and glass that burst into the light of Northern Europe before the year i 200. The construction of these huge, defiant monsters is a stunning achievement of human foresight - or rather, I ought to say, since they were built before any mathematician knew how to compute the forces in them, of human insight. Of course it did not happen without mistakes and some sizeable failures. But what must strike the mathematician most about the Gothic cathedrals is how sound the insight in them was, how smoothly and rationally it progressed from the experience of one structure to the next.
The cathedrals were built by the common consent of townspeople, and for them by common masons. They bear almost no relation to the everyday, useful architecture of the time, and yet in them improvisation becomes invention at every moment. As a matter of mechanics, the design had turned the semicircular Roman arch into the high, pointed Gothic arch in such a way that the stress flows through the arch to the outside of the building.

Rock art of North America, which consists of pictographs constructed from circles, spirals and lines, also seems to have its origins in dreams, and a significance in carrying messages about origins and group identity across generations. Reaching from the Arctic Circle to Tierra del Fuego there is tremendous variety in all aspects of indigenous art from prehistory to the arrival of Europeans, differing region by region, era by era, and often tribe by tribe. There are representations of flora and fauna, men and gods, earth and sky; symbols of clan and tribe, religion and magic; formal designs from the primal to the highly intricate. They appear in examples of basketry, weaving, pottery, sculpture, painting, lapidary work, masks, drum-heads, weapons, apparel, beadwork, goldwork, blankets, ponchos, and may other forms.

In the cave art of the European Palaeaolithic we may contemplate on the existence of the bovine quality in art which is 35,000 years old, and may conclude that since then there has really been no fundamental development in our imaginative and technical abilities to represent natural forms that are close to us practically, emotionally, and spiritually. Sometimes the whole body of an animal is contained in the shape of the rock. It was the rock that revealed its animal 'spirit'.

Their common mental ground is specific material features, such as cracks and smooth, rounded surfaces, which are used to enhance animal features in the mind of the artist. Most of the paintings consist of collections of symbols arranged haphazardly on the surface indicating that they were contributed at different times by several individuals. Occasionally they occur as if welded by one person into an overall composition. For example, the Chumash, who once inhabited the coast of southern California from Malibu to Morrow Bay, created painted compositions in which dozens of interrelated shapes were confined within a limited space. At Arrow Head Springs two rounded boulders with painted panels mark a Chumash sacred site on a steep slope overlooking Santa Barbara and the Channel Islands.

Although the animal forms of Palaeolithic art have a high aesthetic profile, they are usually found together with abstract shapes, such as circles, spirals, and grids. These shapes emerge in the trances of modern spiritualists, and people with certain sight defects, where they are generated from particular regions of the brain. These findings have led to the belief that the rock faces played a spiritual role in the social life of prehistoric peoples. Beyond the rock face was their spirit world; the rock wall is a spiritual place where shamans sought power in a personal interaction at an important boundary between the living and material worlds. Trances have a practical purpose- healing people who are sick. In other words, in making art against stone, a spiritual healer was trying to understand what the brain makes us feel.
2.2.2 The Ark
In the 1830s, Austen Henry Layard, an impecunious young man learning to become a solicitor in his uncle's London office was finding it difficult to keep his mind on dry legal texts. He was restless and longed to travel, above all to see the lands described in The Thousand and One Nights, which had stimulated his imagination since he was a boy. In 1839 he set out to travel overland to Ceylon, but got no further than the mounds the the ancient cities of Nineveh and Calah (Nimrud).  There he spent most of the next ten years excavating the remains of a civilization that belonged to a period far older than that of the caliphs.
Most important perhaps were the thousands of tablets, inscribed with cuneiform characters, which he uncovered in the library of King Assurbanipal at Nineveh and which, more than anything else, have enabled scholars to build up our present knowledge of the Assyrian and Babylonian world. Hormuzd Rassam, Layard's former assistant who from 1852 carried on the excavations at Nineveh, found among those tablets a version of the Flood older than the biblical narrative, the beginning of which runs as follows:
Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch. And this is the fashion which thou shalt make it of: The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits. A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it. And, behold, I even I, do bring a flood of waters upon the earth, to destroy all flesh. . . . But with thee will I establish my covenant; and thou shalt come into the ark. . . .
To judge from this account in Genesis, Noah's ark was a floating home planned with much thought and large enough to receive a numerous clan, its livestock and the necessary provisions, rather than a complete zoological collection. Had such ships really existed in prehistoric times? And what lay behind this diluvial legend? The excavations at Nineveh allowed a corner of the curtain to be lifted for the first time and helped to clear up some of the mystery in which the Flood was wrapped. Some of the tablets, which were sent to the British Museum, contained extracts from the earliest known great epic poem of humanity, the story of the tyrant, hero and demi- god Gilgamesh, and narrated episodes of a catastrophic deluge in much more detail than is given in Genesis.
Many years were needed for the deciphering of the cuneiform script. It was George Smith of the British Museum who in 1872 unravelled the Gilgamesh epic—with growing wonder, for the correspondence with Genesis was amazing. But the texts were not complete, and Smith himself went out to Nineveh in 1873 and again in 1874 to seek the missing portions in the ruins of the King's library. He was successful, but died on his way home in 1876 at the early age of 36. With the deciphering of the Gilgamesh epic the world learned, to the confusion of some and the joy of others, of the existence of a story of the Creation earlier than that of the Bible and bearing a striking resemblance to the account in Genesis. The Hebrew authors of the Old Testament had apparently dipped into a source of legends common to both texts.
Noah's counterpart in the epic of Gilgamesh, Utnapishtim, advised by the god Ea also builds a ship which he covers with pitch inside and out; and,
'all I possessed I laded aboard her . . . into the ship I embarked all my kindred and family . . . cattle and beasts of the field. . . .' For six days and nights hurricane, deluge and tempest swept the land; when the seventh day came, ' assuaged was the deluge, so did I look on the day ... all human back to its clay was returned, and fen was level with roof-tree . . . into the distance gazed, to the furthest bounds of the ocean, land was upreared at twelve points, and the Ark on the Mountain of Nisir grounded.' 
Then Utnapishtim releases one after the other a dove, a swallow and a raven. The raven discovers that the waters have abated, and finds food to eat. Utnapishtim leaves the Ark and makes a sacrifice to the gods.
The epic of Gilgamesh, which dates from the Sumerians, was taken up and copied by the Babylonians, the Assyrians, the Hittites and the other nations of the Near East, who completed it and touched it up. Most of it refers to the multi-millenary struggle between the people of northern and southern Mesopotamia. In the course of the centuries the legends centred upon kings; gods and heroes were woven in. Then, at a time which the most recent research places in the second millennium before Christ, the legend of the Flood was incorporated in the epic of Gilgamesh: it had been known five thousand years ago to the river people of the lower Euphrates.
Now Genesis specifies that Abraham, progenitor of the Hebrew people, was born at Ur, a Sumerian town situated on the lower Euphrates, and it seems reasonable to infer that it was he who introduced the legend of the Flood into the future Promised Land. Later, when the Hebrews began to write the history of their nation, they included with other traditions of foreign provenance this one relating to a disastrous flood, quite inconceivable in a dry country such as Palestine. It meant something entirely different in an area as subject to inundation as the Euphrates valley.
Almost all peoples living close to the banks of large rivers have flood legends. The Edda of Scandinavia, the Vedas of India, the myths of Persia and China, of the Eskimos and Polynesians, all tell of deluges which drowned mankind; lesser risings of the water figure in the myths of the Incas, the Mayas and the Aborigines of Australia. As Alexander von Humboldt reported, the Indians of the Orinoco spoke of legendary ancestors who ' at the time of the great waters' were said to have reached mountain peaks in their canoes. The natives of Fiji—much as in the epic of Gilgasmesh or in the Old Testament—attribute the mythological flood to divine punishment. On the other hand nations which have virtually no contact with the water, such as the inhabitants of Central Asia or the Berbers of Africa, have no knowledge of this sort of legend.
