It was actually eight years ago that Professor Daniela did me the honors of inviting me to deliver these two lectures. For various reasons, this could not materialize. Recently, on two occasions when I visited him, he reminded me that I had to accomplish that, task; and, the last time, I promised him that I would do it a few months later when I would have to return to India for another purpose. I am most grateful to him, indeed, for his kind attention, and for giving me the opportunity to take up for a while studies that I had long given up to concentrate on more technical matters.
I am also grateful for their kindness to Professor Ghatage, the present Honorary Secretary of the Bhandarkar Oriental Research Institute, all the’ scholars associated with the Institute, and the staff of the Institute.
