But, in spite of all these precautions, the King, like his subjects, lived in constant fear. He never showed himself to the people, except surrounded by his ten thousand guards. If he gave an audience, the person admitted to the royal presence was compelled, on pain of death, to present himself dressed in a robe with long sleeves falling over the hands, so that he should not be able to use his hands against his sovereign. If he entertained guests at his table, those among them who were considered the most faithful were placed at his right hand, and the less trusted at his left, because, in case of need, he would be better able to defend himself with the right hand than with the left. Each dish that was set before him was first tasted by an officer in the royal presence, lest there should be poison in the food, and in like manner, the cup-bearer always drank first from the cup that he handed. Under such a system of mutual fear and distrust, the seeds of ruin and decay were sown throughout the Persian empire, and each succeeding century saw it tottering more helplessly towards its final overthrow. But from without everything appeared fair and prosperous, and up to the very last, the Great Kings were careful to maintain all the pomp and splendour of imperial power. III HELLAS Beyond the great Persian Empire, on the other side of the Hellespont, was the little country of Hellas, or Greece. The Hellenes, or Greeks, as they are often called, were a race of men who had for centuries trained themselves in the art of noble thinking and noble living, and they looked down with some scorn on their less cultivated neighbours, to whom they gave, one and all, the name of Barbarians. In many respects Hellas was a complete contrast to Persia. The country was a very small one, and it was further divided into a number of tiny states, each with a free government of its own, and independent of all the rest. To the Hellene citizen, the one supreme necessity of life was freedom, and consequently in almost all the states the government was in the hands of men chosen by the people. Now and again a monarchy would be established in one or other of the states, but it never lasted long, and in their horror of tyrants, the Hellenes were apt to overlook the advantages of a firm, stable government. It is true that in Hellas there were many slaves, but they formed a class apart and were in no sense citizens. The citizens themselves were free, and the Hellenes were convinced that honour, courage, and high-mindedness can only flourish among free men. It was their greatest pride to recall the battles fought by their countrymen in former days against the Barbarians of Persia, when, although outnumbered by ten to one, a handful of free men had put to flight a host of slaves.
