The story of Ráma is one that has fascinated all generations of Hindus, and is full of interest for us. Apart, however, from its charm as a story, it presents a picture of ancient India, which is in many respects unique, and suggests perplexing questions of history, mythology, social life, topography, etc. Many of those questions permit of endless debate and little solid result, for there is no firm ground to rest upon, but the geographical questions are in a better position. India has been surveyed most accurately and completely, and we know that what it is now, it was in ancient times, except that changes have occurred in the courses of some rivers in the plains of North India; and these changes may often be detected. There is plenty of the fabulous in Hindu geography, but it is confined, as a rule, to outside lands, and the allusions to purely Indian topography are generally sober. The main features of the country were adequately known in very early times. The Aryans were well acquainted with all North India as far as the confines of Bengal proper, and the chief mountains and rivers of South India were known. Wars and caravans (of which we have a graphic instance in the story of Nala), helped greatly in opening out new territories as in all lands and ages, but it was the religious ascetics who were the pioneers in discovery, and who appear to have contributed most to a knowledge of the country.
