The Milanda Panna is a famous work of Buddhist literature, probably compiled in the 1st century B.C. It presents Buddhist doctrine in a dialogue between a Bactrian Greek,Menander I, who plays the 'Devil's Advocate' and a Buddhist sage, Nagasena. The introduction outlines the historical background against which the dialogues took place, indicating the meeting of two great cultures that of ancient Greece and the Buddhism of the Indus valley, which was the legacy of the great Emperor Asoka.
