The first Egyptian who thus settled in Greece was a prince called In'a-chus. Landing in that country, which has a most delightful climate, he taught the Pelasgians how to make fire and how to cook their meat. He also showed them how to build comfortable homes by piling up stones one on top of another, much in the same way as the farmer makes the stone walls around his fields. The Pelasgians were intelligent, although so uncivilized; and they soon learned to build these walls higher, in order to keep the wild beasts away from their homes. Then, when they had learned the use of bronze and iron tools, they cut the stones into huge blocks of regular shape. These stone blocks were piled one upon another so cleverly that some of the walls are still standing, although no mortar was used to hold the stones together. Such was the strength of the Pelasgians, that they raised huge blocks to great heights, and made walls which their descendants declared must have been built by giants. As the Greeks called their giants Cy'clops, which means "round-eyed," they soon called these walls Cy-clo-pe'an; and, in pointing them out to their children, they told strange tales of the great giants who had built them, and always added that these huge builders had but one eye, which was in the middle of the forehead. Some time after Inachus the Egyptian had thus taught the Pelasgians the art of building, and had founded a city called Ar'gos, there came a terrible earthquake. The ground under the people's feet heaved and cracked, the mountains shook, the waters flooded the dry land, and the people fled in terror to the hills. In spite of the speed with which they ran, the waters soon overtook them. Many of the Pelasgians were thus drowned, while their terrified companions ran faster and faster up the mountain, nor stopped to rest until they were quite safe. Looking down upon the plains where they had once lived, they saw them all covered with water. They were now forced to build new homes; but when the waters little by little sank into the ground, or flowed back into the sea, they were very glad to find that some of their thickest walls had resisted the earthquake and flood, and were still standing firm. The memory of the earthquake and flood was very clear, however. The poor Pelasgians could not forget their terror and the sudden death of so many friends, and they often talked about that horrible time. As this flood occurred in the days when Og'y-ges was king, it has generally been linked to his name, and called the Deluge (or flood) of Ogyges. III. THE FOUNDING OF MANY IMPORTANT CITIES. Some time after Inachus had built Argos, another Egyptian prince came to settle in Greece. His name was Ce'crops, and, as he came to Greece after the Deluge of Ogyges, he found very few inhabitants left. He landed, and decided to build a city on a promontory northeast of Argos. Then he invited all the Pelasgians who had not been drowned in the flood to join him.
