For over nine years the siege was carried on without one side or the other gaining any important victory. The Trojans were protected by their walls, which the Greeks were unable to break down, for the ancients had no such powerful engines of war as those used in armies of the present day. The strongest buildings may now be easily destroyed by cannon; but in those days they had no cannon or gunpowder or dynamite. Success in war in ancient times depended almost entirely on the bravery of the soldiers or on strategy and artifice, in which, as we shall see, the king of Ithaca was much skilled. The Greek and Trojan warriors fought with swords, axes, bows and arrows, and javelins, or long spears tipped with sharp iron points. Sometimes they used huge stones which the heroes hurled at the foe with the full strength of their powerful arms. They had shields of circular or oval shape, which they wore on the arm to ward off blows, and which could be moved at pleasure so as to cover almost any part of the body. Their chests were protected by corselets or breastplates made of metal, and metal greaves, or boots, incased their legs from the knees to the feet. On their heads they wore helmets, usually of brass. The chiefs fought in chariots, from which they darted their spears at the enemy with such force and so true an aim as to wound or kill at a considerable distance. The chariots were two-wheeled, open at the back, and often drawn by three horses. They usually carried two warriors, both standing, and the charioteer, or driver, was generally the companion or friend, and not the servant, of the fighters who stood behind him. Sometimes the warriors came down from their chariots and fought hand to hand at close quarters with the enemy. The common soldiers always fought on foot. There were no horse soldiers. But in the Trojan War success or defeat did not always depend on the bravery of the soldiers or on the skill or strategy of the generals. Very much depended on the gods. We have seen how those divine beings had to do with the events that led to the war. We shall also see them taking part in the battles, sometimes giving victory to one side and sometimes to the other. The Trojan War was in fact as much a war of the gods as of men, and in Homer's story we find Jupiter and Juno and Apollo and Neptune and Venus and Minerva mentioned almost as frequently as the Greek and Trojan heroes. In the beginning of the Iliad we find Apollo sending a plague among the Greeks because of an insult offered to his priest, Chryʹses; for the daughter of Chryses, a beautiful maiden named Chry-seʹis, was carried off by Achilles after the taking of Theʹbe, a town of Mysia.
