The Pelasgians who joined this young hero helped him to build great walls all around his town. These were provided with massive gateways and tall towers, from which the soldiers could overlook the whole country, and see the approach of an enemy from afar. [Illustration: The Lion Gate, Mycenae.] This same people built tombs for some of the ancient kings, and many treasure and store houses. These buildings, buried under earth and rubbish, were uncovered a few years ago. In the tombs were found swords, spears, and remains of ancient armor, gold ornaments, ancient pieces of pottery, human bones, and, strangest of all, thin masks of pure gold, which covered the faces of some of the dead. Thus you see, the Pelasgians little by little joined the new colonies which came to take possession of the land, and founded little states or countries of their own, each governed by its own king, and obeying its own laws. IV. STORY OF DEUCALION. The Greeks used to tell their children that Deu-ca'li-on, the leader of the Thes-sa'li-ans, was a descendant of the gods, for each part of the country claimed that its first great man was the son of a god. It was under the reign of Deucalion that another flood took place. This was even more terrible than that of Ogyges; and all the people of the neighborhood fled in haste to the high mountains north of Thes'sa-ly, where they were kindly received by Deucalion. When all danger was over, and the waters began to recede, they followed their leader down into the plains again. This soon gave rise to a wonderful story, which you will often hear. It was said that Deucalion and his wife Pyr'rha were the only people left alive after the flood. When the waters had all gone, they went down the mountain, and found that the temple at Del'phi, where they worshiped their gods, was still standing unharmed. They entered, and, kneeling before the altar, prayed for help. A mysterious voice then bade them go down the mountain, throwing their mother's bones behind them. They were very much troubled when they heard this, until Deucalion said that a voice from heaven could not have meant them to do any harm. In thinking over the real meaning of the words he had heard, he told his wife, that, as the Earth is the mother of all creatures, her bones must mean the stones. Deucalion and Pyrrha, therefore, went slowly down the mountain, throwing the stones behind them. The Greeks used to tell that a sturdy race of men sprang up from the stones cast by Deucalion, while beautiful women came from those cast by Pyrrha.
