When once the tragedy had become part of Greek life, the people took it very seriously and never went to the theatre to give their minds a vacation. A new play became as important an event as an election and a successful playwright was received with greater honors than those bestowed upon a general who had just returned from a famous victory. THE PERSIAN WARS HOW THE GREEKS DEFENDED EUROPE AGAINST ASIATIC INVASION AND DROVE THE PERSIANS BACK ACROSS THE ÆGEAN SEA The Greeks had learned the art of trading from the Ægeans who had been the pupils of the Phœnicians. They had founded colonies after the Phœnician pattern. They had even improved upon the Phœnician methods by a more general use of money in dealing with foreign customers. In the sixth century before our era they had established themselves firmly along the coast of Asia Minor and they were taking away trade from the Phœnicians at a fast rate. This the Phœnicians of course did not like but they were not strong enough to risk a war with their Greek competitors. They sat and waited nor did they wait in vain. In a former chapter, I have told you how a humble tribe of Persian shepherds had suddenly gone upon the warpath and had conquered the greater part of western Asia. The Persians were too civilised to plunder their new subjects. They contented themselves with a yearly tribute. When they reached the coast of Asia Minor they insisted that the Greek colonies of Lydia recognize the Persian Kings as their over-Lords and pay them a stipulated tax. The Greek colonies objected. The Persians insisted. Then the Greek colonies appealed to the home-country and the stage was set for a quarrel. For if the truth be told, the Persian Kings regarded the Greek city-states as very dangerous political institutions and bad examples for all other people who were supposed to be the patient slaves of the mighty Persian Kings. [Illustration: THE PERSIAN FLEET IS DESTROYED NEAR MOUNT ATHOS] Of course, the Greeks enjoyed a certain degree of safety because their country lay hidden beyond the deep waters of the Ægean. But here their old enemies, the Phœnicians, stepped forward with offers of help and advice to the Persians. If the Persian King would provide the soldiers, the Phœnicians would guarantee to deliver the necessary ships to carry them to Europe. It was the year 492 before the birth of Christ, and Asia made ready to destroy the rising power of Europe. As a final warning the King of Persia sent messengers to the Greeks asking for “earth and water” as a token of their submission. The Greeks promptly threw the messengers into the nearest well where they would find both “earth and water” in large abundance and thereafter of course peace was impossible.
