Famous Men of The Middle Ages

Sculpture may be broadly defined as the art of representing observed or imagined objects in three physical dimensions. Sculpture may take the form of a biological organism, a statue, or a frozen light sculpture involving laser bursts preserved in a cube of photosensitive gel.3058 Sculpturing may be computerized in the creation: An artist designs a composition, say, in wax, and a machine-driven laser scalpel carves perfect copies in gold or stone, on radium or plutonium ingots, in miniature (as on a precious gem such as ruby or diamond), or in some architectural medium bigger than life.3059 Larry Niven’s "kdatlyno touch sculpture" could be constructed from a vibrating metal surface with variable textural and vibrational modes, but it would have to be extremely wear-resistant to survive fondling by millions of spectators’ hands. Similar in concept are the "tactoids" imagined by Arthur C. Clarke, an egg-shaped time-varying polytexturic handheld sculptural form that "does to the sense of touch what a kaleidoscope does to vision."1947

Sculptures need not necessarily involve the solid phase. Ivan Sanderson has described a unique form of dynamic water-sculpture that echolocating pelagic ETs might perfect:

Certain substances glow in total darkness owing to the release of photons caused by the breakdown of materials that have become "charged" through the absorption of sunlight. What we see in the sea is called luminescence and is produced chemically by living things, most notably by a tiny single-celled animal known as Noctiluca miliaris. These creatures light up when stimulated in various ways -- as mechanically by a ship’s bow waves and wake.... Ultrasonic vibrations of the required intensity could be generated by a large marine animal; indeed, dolphins and whales generate just such sounds. A beautifully coruscating whorl of light could be engendered by two porpoises, "singing" in close harmony.632

Sentient dolphins, in other words, could create optical interference patterns by echolocating in pairs near the same frequency, creating a dynamic light and-sound sculpture against a three-dimensional "screen" of luminescent microscopic lifeforms suspended in the ocean.*

Rainbows are a form of natural sculpture, and sentient creatures may be able to generate similar effects artificially. Radio vision aliens might construct a giant diffraction grating in the form of metal picket fences or using closely spaced electrically-conductive natural plant growth. Spaced 1-100 centimeters apart, such patterns would yield three or four orders of rainbow-like spectra as an observer moved from the front around to the side.

Sonic rainbows are also possible. One way to do it is to send white noise through a field of very large bubbles of air about 1 meter in diameter. Just as light slows in water droplets to form a natural optical rainbow in the sky, sound travels slower in the rising air pockets and is refracted to create what porpoises might call an "airbow." A more elegant technique involves the use of very small air bubbles. As R. McNeill Alexander has pointed out, when bubbles are blown in water a musical note can be heard because in the act of formation the bubble surfaces are set in vibration.230 The properties of pulsating bubbles are such that a bubble of 1 centimeter radius will emit sonic radiation at about 330 Hz; a bubble 0.1 centimeter in radius radiates at 3300 Hz; and so forth. Perhaps as part of an elaborate dance orchestration, sentient dolphins could generate distinctive three-dimensional patterns of glowing water-space ("glowing" in the sonic spectrum) by blowing exactly the right kinds of bubbles at the proper locations with accurate timing. Such a sonic airbow could take on any shape or color desired by the artist.



What about alien architecture? Sociobiologists are aware of many instances of homebuilding among nonhuman animals on Earth.3057,438 Octopuses live in "houses" which they either occupy fortuitously or build from scratch using rocks, pebbles, rusted cans, bottles, or anything else they can find on the sea floor.1000 The honeycomb hives of bees are perhaps the best known instance of animal architecture, and Karl von Frisch has demonstrated that the hexagonal shape of the honeycomb is mathematically optimal in that it encloses the most volume using the least materials.438 And until the coming of mankind the monolithic cities of the termites represented the greatest modification of the natural landscape wrought by animal life. Built of porous clay and oriented exactly along an east-west axis to minimize the heating effects of direct sunlight, termite mounds often reach heights of more than 5 meters and occasionally have diameters as wide as 30 meters across.1000

So we see that both solitary and gregarious creatures on this planet make use of architectural structures. Virtually all human societies utilize some form of shelter, even in the Pacific islands where the climate is so benign that no elaborate housing is really needed. These facts argue strongly for the ubiquity of architecture among extraterrestrial societies.3060

What are the gross physical limits to such construction on any world? Gravity is the first problem.20 According to the Square-Cube Law, the mass of a building which must be supported by its foundation increases as the cube of the linear dimension, whereas the supportive area of the foundation increases only as the square. The compressive strengths of natural and artificial building materials are well known,924,1852 so it is a simple matter to calculate the maximum permissible sizes of structures on other worlds. Maximum height of a given design will vary inversely with gravity. In other words, the highest building on a 2-gee planet can only be about half as high as a similar structure with similar materials constructed here on Earth.

Another major environmental factor is geological activity.61 As we discovered in an earlier chapter, massive planets have more internal energy available to drive thermal convection currents in the mantle. This means more earthquakes. Xenologists therefore expect to find sqatter, more sturdy and temblor-proof buildings on heavy worlds than on light ones, since quakes topple buildings more easily the higher their centers of gravity are from the ground.926,925 This conclusion is reinforced by the observation that high gravity and tectonic activity appear to be highly correlated.

Still another important consideration is wind velocity. Planetologists recognize that planetary rotation is related to wind speed -- generally the faster the rotation, the faster the winds. Also, an empirical relation derived from data from the bodies in our solar system indicates that planetary mass and rotation are also correlated (for reasons unknown) -- the more massive the planet, the shorter its day. Putting these two results together, xenologists expect that massive high-gravity worlds should have faster winds than less massive, low-gravity worlds.

Tall, wispy architectures are less likely on planets with ferocious winds.925 Nevertheless, as Donald Stern once pointed out to the author, architectural forms on high-wind-velocity planets can still have as much variation and height as on Earth:

Wind factor can be compensated for. Under high wind conditions it is not necessary to weight a structure down to make it immovable. A good terran example of this is the Mongolian yurt, a dome-shaped structure of wood latticework covered with hides and a felt-like material ½ cm thick. This structure weighs only a few hundred pounds and is designed to be fairly portable. Yet it can withstand wind velocities up to 140 kph on the open steppes. Even tall structures should be possible under such conditions. (See "Wicker Wonderland" in Keith Laumer’s Galactic Diplomat.) Spire-like city structures could be constructed to serve as a graduated series of windbreaks. They could conceivably be semiflexible, but might prove more livable if they could be rigidly fixed in a giant latticework or grillwork system that would still be capable of breaking up the force of the wind. ("Galloping Gertie," the Tacoma Narrows bridge, collapsed because solid panels were used in the cable suspension; it was later rebuilt using a latticework system.) If spread across the face of a high-wind planet, such structures could serve to lower the wind factor by several orders of magnitude.2976

Another possibility for windy worlds is to construct buildings in the shape of vertical airfoils, streamlined, gimballed and pointing into the wind for maximum stability.**

Rather than using static construction materials, it has been suggested that ETs may wish to employ what is called "biotecture" or biological architecture. One biostructure grown by architect Rudolf Doernach near Stuttgart, Germany consists of living hazel trees bent into an arched framework over which dense foliage plants have been grown to form protective walls. Frank Lloyd Wright once designed a mile-high skyscraper with a foundation patterned after the taproot systems by which many plant species anchor themselves to the ground. Biotects dream of using genetically altered plants to grow predesigned habitable shapes, and crystalline minerals chemically treated to grow into specific forms. Marine animals such as shellfish and coral could be genetically doctored and used in biotecture. As one science fiction writer describes it:

A genetic manipulation of ordinary sea coral, it was the cheapest building material known. The only real cost was in the plastic balloon that guided the growth of the coral and enclosed the coral’s special airborne food. The remnants of the shaping balloon gave all architectural coral buildings their telltale bulge. The exposed walls can be polished to a shining pink sheen, Even after sunset the house glowed softly.231

Inside living houses we might find living furniture! A genetically altered canine, bred for patience and furriness, could serve as a self-moving chair (the "chairdog"); another variety could be used as a bed with a comfy conformable surface (the "bedog");2615 a modified Galapagos tortoise species could serve as living tables and desks (the "tableturtle"); and so forth.

A wide variety of unusual architectural forms have been proposed by many writers, including the cryotectural Ice City,3065 Ferrocement (Ant Farm) Structures,3062 Aerotecture,3062 Cybertecture,3062 Self-Building Symbiotic Structures,3065 the Sensitive House,3064 the Crystal Caves,3064 Archigram and Modular Habitats,3062 Chemitecture and Laser Architecture,3065,3063 Urban Microclimates,3062 Edible Houses,3064 Terratecture and Geotecture,3061 Green house Cities,3062 Kinetic Architecture,3063 the Biopolis,3067 Ecopolis,3062 and the Biomorphic Biosphere Megastructure.3066 Extraterrestrial architects and biotects may exploit these and countless other remarkable design approaches in the construction of buildings and habitats on other worlds.

* The gaseous phase is also a possibility -- "weather sculpture" has been suggested by at least one science fiction writer.3077

** Environmental and sensorial factors may also be significant. Olfactory beings may design "smell vents" into their buildings rather than windows and skylights.1000 The equivalent for tactile ETs would be vibration transducers mounted into walls. And radio-visioned aliens inhabiting starless planets should have a most unique variety of interior lighting. Since radio illumination percolates up from the ground, and deeper means hotter and thus brighter, ETs might drill vertical shafts to bring forth "radio light." Houses might be built around these radio wells.

 

Famous Men of The Middle Ages

 

 

Preface

 

 

The study of history, like the study of a landscape, should begin with the most conspicuous features. Not until these have been fixed in memory will the lesser features fall into their appropriate places and assume their right proportions.

 

 

The famous men of ancient and modern times are the mountain peaks of history. It is logical then that the study of history should begin with the biographies of these men.

 

 

Not only is it logical; it is also pedagogical. Experience has proven that in order to attract and hold the child's attention each conspicuous feature of history presented to him should have an individual for its center. The child identifies himself with the personage presented. It is not Romulus or Hercules or Cesar or Alexander that the child has in mind when he reads, but himself, acting under similar conditions.

 

 

Prominent educators, appreciating these truths, have long recognized the value of biography as a preparation for the study of history and have given it an important place in their scheme of studies.

 

 

The former practice in many elementary schools of beginning the detailed study of American history without any previous knowledge of general history limited the pupil's range of vision, restricted his sympathies, and left him without material for comparisons. Moreover, it denied to him a knowledge of his inheritance from the Greek philosopher, the Roman lawgiver, the Teutonic lover of freedom. Hence the recommendation so strongly urged in the report of the Committee of Ten — and emphasized, also, in the report of the Committee of Fifteen — that the study of Greek, Roman and modern European history in the form of biography should precede the study of detailed American history in our elementary schools. The Committee of Ten recommends an eight years' course in history, beginning with the fifth year in school and continuing to the end of the high school course. The first two years of this course are given wholly to the study of biography and mythology. The Committee of fifteen recommends that history be taught in all the grades of the elementary school and emphasizes the value of biography and of general history.

 

 

The series of historical stories to which this volume belongs was prepared in conformity with the foregoing recommendations and with the best practice of leading schools. It has been the aim of the authors to make an interesting story of each man's life and to tell these stories in a style so simple that pupils in the lower grades will read them with pleasure, and so dignified that they may be used with profit as text-books for reading.

 

 

Teachers who find it impracticable to give to the study of mythology and biography a place of its own in an already overcrowded curriculum usually prefer to correlate history with reading and for this purpose the volumes of this series will be found most desirable.

 

 

The value of the illustrations can scarcely be over-estimated. They will be found to surpass in number and excellence anything heretofore offered in a school-book. For the most part they are reproductions of world-famous pictures, and for that reason the artists' names are generally affixed.

 

 

The Gods of the Teutons

 

 

In the little volume called The Famous Men of Rome you have read about the great empire which the Romans established. Now we come to a time when the power of Rome was broken and tribes of barbarians who lived north of the Danube and the Rhine took possession of lands that had been part of the Roman Empire . These tribes were the Goths, Vandals, Huns, Franks and Anglo-Saxons. From them have come the greatest nations of modern times. All except the Huns belonged to the same race and are known as Teutons. They were war-like, savage and cruel. They spoke the same language — though in different dialects — and worshiped the same gods. Like the old Greeks and Romans they had many gods.

 

 

Woden, who was also called Odin, was the greatest of all. His name means "mighty warrior, " and he was king of all the gods. He rode through the air mounted on Sleipnir, an eightfooted horse fleeter than the eagle. When the tempest roared the Teutons said it was the snorting of Sleipnir. When their ships came safely into port they said it was Woden's breath that had filled their sails and wafted their vessels over the blue waters.

 

 

Thor, a son of Woden, ranked next to him among the gods. He rode through the air in a chariot drawn by goats. The Germans called him Donar and Thunar, words which are like our word thunder. From this we can see that he was the thunder god. In his hand he carried a wonderful hammer which always came back to his hand when he threw it. Its head was so bright that as it flew through the air it made the lightning. When it struck the vast ice mountains they reeled and splintered into fragments, and thus Thor's hammer made thunder.

 

 

Another great god of our ancestors was Tiew. He was a son of Woden and was the god of battle. He was armed with a sword which flashed like lightning when he brandished it. A savage chief named Attila routed the armies of the Romans and so terrified all the world that he was called "The Scourge of God." His people believed that he gained his victories because he had the sword of Tiew, which a herdsman chanced to find where the god had allowed it to fall. The Teutons prayed to Tiew when they went into battle.

 

 

Frija (free' ya) was the wife of Woden and the queen of the gods. She ruled the bright clouds that gleam in the summer sky, and caused them to pour their showers on meadow and forest and mountain.

 

 

Four of the days of the week are named after these gods. Tuesday means the day of Tiew; Wednesday, the day of Woden; Thursday, the day of Thor; and Friday, the day of Frija.

 

 

Frija's son was Baldur; who was the favorite of all the gods. Only Loki, the spirit of evil, hated him. Baldur's face was as bright as sunshine. His hair gleamed like burnished gold. Wherever he went night was turned into day.

 

 

One morning when he looked toward earth from his father Woden's palace black clouds covered the sky, but he saw a splendid rainbow reaching down from the clouds to the earth. Baldur walked upon this rainbow from the home of the gods to the dwellings of men. The rainbow was a bridge upon which the gods used to come to earth.

 

 

When Baldur stepped from the rainbow-bridge to the earth he saw a king's daughter so beautiful that he fell in love with her.

 

 

But an earthly prince had also fallen in love with her. So he and Baldur fought for her hand. Baldur was a god and hence was very much stronger than the prince. But some of Baldur's magic food was given to the prince and it made him as strong as Baldur.

 

 

Frija heard about this and feared that Baldur was doomed to be killed. So she went to every beast on the land and every fish of the sea and every bird of the air and to every tree of the wood and every plant of the field and made each promise not to hurt Baldur.

 

 

But she forgot the mistletoe. So Loki, who always tried to do mischief, made an arrow of mistletoe, and gave it to the prince who shot and killed Baldur with it.

 

 

Then all the gods wept, the summer breeze wailed, the leaves fell from the sorrowing trees, the flowers faded and died from grief, and the earth grew stiff and cold. Bruin, the bear, and his neighbors, the hedgehogs and squirrels, crept into holes and refused to eat for weeks and weeks.

 

 

The pleasure of all living things in Baldur's presence means the happiness that the sunlight brings. The sorrow of all living things at his death means the gloom of northern countries when winter comes.

 

 

The Valkyries were beautiful female warriors. They had some of Woden's own strength and were armed with helmet and shield and spear. Like Woden, they rode unseen through the air and their horses were almost as swift as Sleipnir himself. They swiftly carried Woden's favorite warriors to Valhalla , the hall of the slain. The walls of Valhalla were hung with shields; its ceiling glittered with polished spearheads. From its five hundred and forty gates, each wide enough for eight hundred men abreast to march through, the warriors rushed every morning to fight a battle that lasted till nightfall and began again at the break of each day. When the heroes returned to Valhalla the Valkyries served them with goblets of mead such as Woden drank himself.

 

 

The Teutons believed that before there were any gods or any world there was a great empty space where the world now is. It was called by the curious name Ginnungagap, which means a yawning abyss.

 

 

To the north of Ginnungagap it was bitterly cold. Nothing was there but fields of snow and mountains of ice. To the south of Ginnungagap was a region where frost and snow were never seen. It was always bright, and was the home of light and heat. The sunshine from the South melted the ice mountains of the North so that they toppled over and fell into Ginnungagap. There they were changed into a frost giant whose name was Ymir (e'mir). He had three sons. They and their father were so strong that the gods were afraid of them.

 

 

So Woden and his brothers killed Ymir. They broke his body in pieces and made the world of them. His bones and teeth became mountains and rocks; his hair became leaves for trees and plants; out of his skull was made the sky.

 

 

But Ymir was colder than ice, and the earth that was made of his body was so cold that nothing could live or grow upon it. So the gods took sparks from the home of light and set them in the sky. Two big ones were the sun and moon and the little ones were the stars. Then the earth became warm. Trees grew and flowers bloomed, so that the world was a beautiful home for men.

 

 

Of all the trees the most wonderful was a great ash tree, sometimes called the "world tree." Its branches covered the earth and reached beyond the sky till they almost touched the stars. Its roots ran in three directions, to heaven, to the frost giants' home and to the under-world, beneath the earth.

 

 

Near the roots in the dark under-world sat the Norns, or fates. Each held a bowl with which she dipped water out of a sacred spring and poured it upon the roots of the ash tree. This was the reason why this wonderful tree was always growing, and why it grew as high as the sky.

 

 

When Woden killed Ymir he tried to kill all Ymir's children too; but one escaped, and ever after he and his family, the frost giants, tried to do mischief, and fought against gods and men.

 

 

According to the belief of the Teutons these wicked giants will some day destroy the beautiful world. Even the gods themselves will be killed in a dreadful battle with them. First of all will come three terrible winters without any spring or summer. The sun and moon will cease to shine and the bright stars will fall from the sky. The earth will be shaken as when there is a great earthquake; the waves of the sea will roar and the highest mountains will totter and fall. The trees will be torn up by the roots, and even the "world tree" will tremble from its roots to its topmost boughs. At last the quivering earth will sink beneath the waters of the sea.

 

 

Then Loki, the spirit of evil, will break loose from the fetters with which the gods have bound him. The frost giants will join him. They will try to make a secret attack on the gods. But Heimdall, the sentry of heaven, will be on guard at the end of the rainbow-bridge. He needs no more sleep than a bird and can see for a hundred miles either by day or night. He only can sound the horn whose blast can be heard through heaven and earth and the under-world. Loki and his army will be seen by him. His loud alarm will sound and bring the gods together. They will rush to meet the giants. Woden will wield his spear — Tiew his glittering sword — Thor his terrible hammer. These will all be in vain. The gods must die. But so must the giants and Loki.

 

 

And then a new earth will rise from the sea. The leaves of its forests will never fall; its fields will yield harvests unsown. And in a hall far brighter than Woden's Valhalla the brave and good will be gathered forever.
