GREEK METHODS OF BUILDING STILL USED. If we look at our large buildings, we shall see much to remind us of the Greek buildings. Sometimes the exact form of the Greek building is imitated; sometimes this form is changed as the Romans changed it, or as it was changed by builders who lived after the time of the Romans. If the model of the whole building is not used, there are similar pillars, or gables, or the sculpture in the pediment and the frieze is imitated. The Greeks had three kinds of pillars, named Doric, Ionic, and Corinthian. The Doric is simple and solid, the Ionic shows in its capital, or top, delicate and beautiful curves, while the Corinthian is adorned with leaves springing gracefully from the top of the pillar.

The first Greek theater was only a smooth open space near a hillside, with a tent, called a _skene_, or scene, in which the actors dressed. Later an amphitheater of stone seats was constructed on the hillside, and across the open end was placed the _scene_, which had been changed into a stone building. On its front sometimes a house or a palace was painted, just as nowadays theaters are furnished with painted scenery. In these open-air theaters thousands of people gathered. Plays were generally given as a part of religious festivals, and there were contests between writers to see which could produce the best play. Sometimes the plays followed one another for three days from morning until night. Many of them are so interesting that people still read them, after twenty-five hundred years. The Romans studied them, and so do modern men who are preparing themselves to write plays. [Illustration: THE MODERN STADIUM AT ATHENS] THE STADIUM. A building which somewhat resembled the theater was the stadium, where races were run. The difference was that it was oblong instead of half round. The most famous stadium, at Olympia, was seven hundred and two feet long, with raised seats on both sides and around one end of the running track. The other end was open. About fifty thousand persons used to gather there to watch the races. PORTICOES. There were other buildings, some for meeting places, some for gymnasiums, and still others called porticoes, where the judges held court or the city officers carried on their business. The porticoes were simply rows of columns, roofed over, with occasionally a second story. As they stretched along the sides of a square or market place they added much to the beauty of a city.
