Megasthenes was among the first foreigners to have visited India in historical times and given an eyewitness account of conditions prevailing in this country during the fourth century B.C. He was the ambassador of Seleucus Nicator at the court of Chandragupata Maurya and he had the opportunity to travel extensively in the country and observe closely the proceedings at the royal court, various aspects of military and civil administration, the geography of the country, the social and economic conditions of the people and the political institutions. He put down his observations in four volumes entitled ?Indica?.?Indica? in its original form has now been lost, but some later writers like Diodorus, Pliny, Strabo and Arrian have quoted from the work. Barring the few instances where Megasthenes had to rely on hearsay, his account of India is highly valued for its accuracy and authenticity. This story of Megasthenes is based on his own account of India of his times. For purposes of coherence and lucidity we have adopted a sequence of our own to this narration. However, historically the record is accurate.
