The physical features of the country exercised an important influence upon the political destinies of the people. Greece is one of the most mountainous countries of Europe. Its surface is occupied by a number of small plains, either entirely surrounded by limestone mountains or open only to the sea. Each of the principal Grecian cities was founded in one of these small plains; and, as the mountains which separated it from its neighbours were lofty and rugged, each city grew up in solitary independence. But at the same time it had ready and easy access to the sea, and Arcadia was almost the only political division that did not possess some territory upon the coast. Thus shut out from their neighbours by mountains, the Greeks were naturally attracted to the sea, and became a maritime people. Hence they possessed the love of freedom and the spirit of adventure, which have always characterised, more or less the inhabitants of maritime districts. CHAPTER II. ORIGIN OF THE GREEKS AND THE HEROIC AGE. No nation possesses a history till events are recorded in written documents; and it was not till the epoch known by the name of the First Olympiad, corresponding to the year 776 B.C., that the Greeks began to employ writing as a means for perpetuating the memory of any historical facts. Before that period everything is vague and uncertain; and the exploits of the heroes related by the poets must not be regarded as historical facts. The PELASGIANS are universally represented as the most ancient inhabitants of Greece. They were spread over the Italian as well as the Grecian peninsula; and the Pelasgic language thus formed the basis of the Latin as well as of the Greek. They were divided into several tribes, of which the Hellenes were probably one: at any rate, this people, who originally dwelt in the south of Thessaly, gradually spread over the rest of Greece. The Pelasgians disappeared before them, or were incorporated with them, and their dialect became the language of Greece. The Hellenes considered themselves the descendants of one common ancestor, Hellen, the son of Deucalion and Pyrrha. To Hellen were ascribed three sons, Dorus, Xuthus, and AEolus. Of these Dorus and AEolus gave their names to the DORIANS and AEOLIANS; and Xuthus; through his two sons Ion and Achaeus, became the forefather of the IONIANS and ACHAEANS. Thus the Greeks accounted for the origin of the four great divisions of their race. The descent of the Hellenes from a common ancestor, Hellen, was a fundamental article in the popular faith. It was a general practice in antiquity to invent fictitious persons for the purpose of explaining names of which the origin was buried in obscurity. It was in this way that Hellen and his sons came into being; but though they never had any real existence, the tales about them may be regarded as the traditional history of the races to whom they gave their names.
