The Mahabharata is one of the great ancient human epic stories. On a par with the Epic of Gilgamesh, the Mahabharata tells of the battles between two acient Indian families. It contains what appear to be references to amazingly sophisticated weapons, flying machines and perhaps even nuclear bombs.
The story has been translated by many scholars over the generations. The version I read is:
"The Mahabharata", Translated by C.V. Narasimhan, Revised Edition, Columbia University Press, 1965.
