18. B. C. 600. About the beginning of this century the foundation of Greek philosophy was laid by Thales of Miletus, a Greek city in Asia. He represents the growth and acuteness of the Greek mind and the approach of its period of greatest activity. He travelled into Egypt in search of wisdom, and was the most able astronomer of his times. He calculated an eclipse of the sun, which, coming on just when two armies, the Median and Lydian, were about to engage in battle, so terrified them that they immediately separated and made peace. He was celebrated as a mathematician, and taught many truths concerning the existence of God which were far in advance of his time, and undertook to account for the origin of all things in a very bold and independent manner. He was one of the famous “Seven Wise Men” of Greece. Solon was held to be the first among the seven. He was an Athenian law-giver and writer, and established a very wise and enlightened system of government in Athens. He was a pure-hearted and clear-sighted man, enjoying the universal respect of the Greeks. Chilo, another of the seven, was a Spartan magistrate, held in the highest esteem for his wisdom. Pittacus of Mitylene, was a law-giver, held in high honor. Bias of Priene, in Ionia, was a very noble-hearted and public-spirited citizen, of universal reputation for wisdom. Cleobulus, of the island of Rhodes, was remarkable for his skill in answering difficult questions, and Periander of Corinth, the ruler, or tyrant, of that place, was the last of the seven. They were all living at the same time. They were only the most eminent among a people who could fully appreciate mental ability. The spirit of inquiry continued to spread rapidly for two hundred years, when the greatest masters, who immortalized themselves and their race by their genius, appeared. 19. In the early part of this century the kingdom of Lydia, in the central part of Asia Minor, rose to great wealth and power. The Lydian kingdom was ancient—many of its customs being similar to those of the Egyptians—and the Etrurians of Italy, a much more polished and cultivated people than the Romans who conquered them, are thought, by some eminent historians, to have been a Lydian colony planted in Italy in unknown times. The Lydian kings made war on the Asiatic Greek colonies and reduced many of them to subjection. Crœsus, the last king of Lydia, was proverbial for his vast wealth. He was conquered by Cyrus, the Persian, in the middle of the next century. 679 B. C. Numa, the second king of Rome, is said to have died. The Romans abstained from war during nearly the whole of his reign, which was occupied in settling the internal affairs of the new state, especially those relating to religion. He was followed by Tullus Hostilius, a very warlike prince, who did much to extend the Roman state.
