The Greeks, after hearing the oracle's words, sent messengers for Achilles; but they could not find him, as he had left home, and no one would tell them where he had gone. As it was of no use to set out without him, according to the oracle's answer, which they thoroughly believed, the army lingered at Aulis in despair. Ulysses, seeing that they would never start unless Achilles were found, now offered to go and get him. Disguised as a peddler, with a pack upon his back, he went first to Achilles' home, where the chattering maids told him all he wished to know, and thence he went to the Island of Scyros. Achilles was so well disguised that Ulysses could not tell him from the king's daughters and their maids: so he made use of a trick to find him out. Among the trinkets in his pack, he put a sword of fine workmanship, and, entering the palace, spread out his wares before the admiring maidens. They all gathered about him; but, while the real girls went into raptures over his ornaments, Achilles grasped the sword, drew it from the scabbard, carefully tested the blade, and swung it with a strong arm. Of course, Ulysses then easily saw that he was not a girl, and, slipping up to him, managed to whisper news of the coming war, and won his promise to join the army at Aulis in a few days. XV. THE SACRIFICE OF IPHIGENIA. True to his promise, Achilles soon came to Aulis with his well-trained soldiers, the Myr'mi-dons, and with him came his friend Pa-tro'clus. All were now eager to start, and ready to embark; but unfortunately there was no favorable wind to fill their sails and waft them over to Asia Minor. Day after day they waited, and offered sacrifices to the gods, but all in vain. At last they again consulted the oracle, who said that the wind would not blow until Iph-i-ge-ni'a, Agamemnon's daughter, were offered up in sacrifice to Di-an'a, goddess of the moon and the chase, whom this king had once offended. Agamemnon at first said that he would not sacrifice his daughter, but finally his companions persuaded him to do so. Just as the priest was about to kill the maiden on the altar, however, the goddess Diana came, and carried her off unharmed, leaving a deer to be sacrificed in her stead. The deer was killed, the wind rose, the sails filled, and the Greek fleet soon came within sight of the high walls and towers of Troy. There, contrary to their expectations, the Greeks found the people ready to fight them; but, after many days' struggle, they saw that they had made no great advance. On the wide plain which stretched out between the city and the sea, the Greek and Tro'jan armies fought many a battle; and sometimes one party, and sometimes the other, had the victory. The men on both sides had been trained to handle their weapons with great skill, and there were many fights in which the Greek heroes met the bravest Trojans. [Illustration]
