Schlegel's work, moreover, aroused so much zeal for the study of Sanskrit in Germany, that the vast progress made since his day in this branch of learning has been mainly due to the labours of his countrymen.
In the early days of Sanskrit studies Europeans became acquainted only with that later phase of the ancient language of India which is familiar to the Pandits, and is commonly called Classical Sanskrit. So it came about that the literature composed in this dialect engaged the attention of scholars almost exclusively down to the middle of the century. Colebrooke had, it is true, supplied as early as 1805 valuable information about the literature of the older period in his essay On the Vedas. Nearly a quarter of a century later, F. Rosen, a German scholar, had conceived the plan of making this more ancient literature known to Europe from the rich
