The science of language has placed it beyond dispute that the languages of the leading European peoples are genealogically related to each other, and that the languages of India and of Persia also belong to the same family of speech. The Indo-European languages, those, namely, of the higher race in India, and of the Persians, and those of the Greeks, Italians, Celts, Germans, Slavs, Letts, and Albanians, approach each other always more nearly as they are traced upwards. Sanscrit is not the source of these tongues but an older sister of the group; the mother language, which the facts prove to have at one time existed, was a highly-inflected speech, and is perhaps more nearly represented by Lettic than by Sanscrit; but it can now be known only by a study of the common features of its surviving children. The fact that the peoples named above are related to each other in point of language led at once, when it was discovered, to the conclusion that they were also of the same race, and must have come originally from the same quarter of the world. Where, then, was the early home of the undivided Aryan[1] race, from which the swarms first issued which were to conquer and rule the various lands? At first it was found in the East; the fact that Indian civilisation was much earlier in time than that of any other Aryan people, naturally suggested this. Professor Max Mueller described in a very poetical way how the European as well as the Indian must find in the East the cradle of his race. From the high tableland of Asia, it was held, the superior races came who were to rule nearly the whole of Europe, while another migration descended towards Persia and the plains of India. [Footnote 1: "Aryan" was the name of the conquering race of India. The title "Indo-European" tells us that the race now dwells in India and in Europe. "Indo-Germanic" describes the group by its Eastern, and what is supposed to be its principal Western, member.]
