"As regards the forms of the Old and Modern Kannada alphabets, they are varieties of the so-called Cave-character, an alphabet which was used for the inscriptions in the cave hermitages of Buddhists in India, and rests on the Southern Ashoka character. This character was about 250 BC employed in the edicts of Buddhist King Ashoka. Different forms of the letters used for the Kannada inscriptions appear at different periods, the earliest form differing in the greatest degree from those of the modern Kannada alphabet. At the time of the composition of the Basavapurana 1369 A. D. the old alphabet had become already out of use, as the author of that work mentions the letters of Old Kannada as belonging to the past."
