"The commentary of Sayana closes the period of original and living scholastic work on the Veda which Yaska’s Nirukta among other important authorities may be said to open. The lexicon was compiled in the earlier vigour of the Indian mind when it was assembling its prehistoric gains as the materials of a fresh outburst of originality; the Commentary is almost the last great work of the kind left to us by the classical tradition in its final refuge and centre in Southern India before the old culture was dislocated and broken into regional fragments by the shock of the Mahomedan conquest. Since then we have had jets of strong and original effort, scattered attempts at new birth and novel combination, but work of quite this general, massive and monumental character has hardly been possible."
