IF Islam had never existed, the Christian countries of the world would probably be less advanced and certainly less varied, than they are. For it was Moslems who gave the West many of its basic skills and ideas. From the eighth to the thirteenth centuries, the Arabs and the other Islamic peoples were the main carriers of western civilization. While Europe was torn by almost constant fighting, Moslem scholars preserved the learning of the ancient world. Other Moslems added discoveries and original works of their own. In time, translators in the parts of Europe that were in closest contact with Islam passed this knowledge on to the Christian world. It helped produce a great intellectual and artistic awakening, the Renaissance, which ended the Middle Ages and ushered m modern times. So the West owes much to Islam. Its debt is specially great in philosophy and science. Many cultural treasures would have been lost forever if it had not been for Moslem scholarship. Among them are the works of three of the greatest thinkers of ancient Greece — the philosopher Aristotle, the physician Galen and the astronomer Ptolemy. These works are the foundations on which Renaissance thinkers built modern learning. In one branch of science, astronomy, the Arabs’ superiority is written across the very heavens‚ for most stars hear Arabic names to this day. Example the Acrab (from aqrab, a scorpion), Altair (from al-tair, the flyer) and Deneb (from dhanab, a tail). Allied to astronomy is mathematics. Taking their cue from work done in ancient India, Arab and Persian mathematicians developed algebra, geometry and trigonometry. They also taught Europeans to use the Arabic figures instead of the clumsy numerals based on the letters of the Roman alphabet. Unlike the ancient Greeks, who often came to conclusions by reasoning alone, the scientists …

THE story of Rome in the years after Sulla’s death was the story of a partnership of power. It was the tale of three men who bargained for the world — a rich man, a poor man and a man who was not only a hero, but looked it. The rich man was Crassus, who had become a millionaire by setting up the only fire department in Rome. The tall buildings and narrow, crowded streets of the city made a fire a constant danger. When one house burned to the ground, the buildings on either side were likely to fall over on top of it. The cry of “Fire!” roused fear in the hearts of men whose wealth was in the buildings they owned. It was the signal, too, for Crassus and his fire-fighting slaves to come on the run. While the slaves got their equipment ready and looked for water, Crassus found the landlord of the burning building and offered to buy it from him. The price he offered was not high, but it was more than the house would be worth after it had been destroyed by fire. If the landlord refused to sell, Crassus shrugged and let the fire burn. Usually, however, the landlord sold and the firemen went to work. When the fire was out, Crassus sent a crew of carpenters to repair the damage. He soon had a building as good as new and worth a great deal more than he had paid for it. If he had talked fast enough, he also owned the buildings next door, which did not even need repairing. Despite such dealings, Crassus was a popular man in the city. He was a good host. In politics, he took the side of the people and he greeted the poorest citizen …
