The Arabs built many beautiful buildings; but these buildings look quite different from those that the Greeks and Romans and Christians built. The doors and window-openings, instead of being square or round, were usually horseshoe-shaped. On the top of their mosques they liked to put domes shaped something like an onion, and at the corners they put tall spires or minarets from which the muezzin could call aloud the hour for prayer. They covered the walls of their buildings with beautiful mosaics and designs. The Mohammedans, however, were very careful that these designs were not copies of anything in nature, for they had a commandment in the “Koran” something like the Christian commandment, “Thou shalt not make ... any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.” Because of this commandment they never made drawings or pictures of any living thing, neither of plants nor flowers nor animals. They thought they would be breaking the commandment if they did. So they made designs out of lines and curves without copying anything from nature. These designs were called Arabesques, and although they were not like anything in nature, they were often very beautiful.
Still another thing:
In Arabia there grew a little bush on which were small berries with seeds inside. The sheep seemed to like these berries and, when they ate them, became very lively. The Arabs themselves tried eating the seeds of these berries with the same effect. Then they made a drink out of these seeds by roasting and grinding them and boiling them in water. This was coffee—which the Arabs had discovered and which is now drunk all over the world.
Still another thing:
The Arabs found out that when the juice of grapes or other fruits or grains spoiled, or fermented, as we call it, a peculiar change took place. Any one who drank this changed juice became greatly excited and even crazy. They called the new thing to which these juices changed, “alcohol,” and they were so much afraid of it and what it did to those who drank it that they forbade every Mohammedan to drink anything containing alcohol, such as wine, beer, or whisky. So the Moslems not only discovered alcohol, but, believing it to be poison, they prohibited its use. They have been prohibitionists, therefore, for more than a thousand years, while all the rest of the world has been using wine and beer and other drinks containing alcohol until the United States only recently forbade their use in this country.
Still another thing:
Woolen cloth which people used for clothes was made from the hair of sheep or goats. As it took the hair of a great many such animals to make a very little cloth, woolen cloth was expensive. The Arabs found out a way of making cloth from a plant, the cotton plant, which of course was much cheaper. Then in order to decorate the cloth and make it pretty and attractive, they stamped the plain cloth with wooden blocks shaped in different forms and dipped in color. This printed cloth that the Arabs had invented was called calico.
Still another thing:
The Arabs made swords and knives of such wonderful steel that the blades could be bent double without breaking. The blades were said to be so keen they could cut through the finest hair if floated on water, a thing that only the sharpest razor will do, and yet at the same time so strong that they could cut through a bar of steel. Such swords were made in the East at a place called Damascus, which is in Arabia, and in the West at a place called Toledo, which is in Spain; and these swords and knives were known as Damascus or Toledo blades. Unfortunately, no one now knows the Arab’s secret for making such marvelous blades. It is what is called a lost art.
Near where Babylon once was the Arabs built a city named Bagdad. You have heard of it if you have ever read any of the “Arabian Nights,” for most of these stories were told about Bagdad. It was the eastern capital of the Moslems. There at Bagdad the Arabs built a great school that was famous for many, many years. At Cordova in Spain was the western capital of the Moslems, and there they built another great school.
