This is the earliest example of a pattern that has been repeated in history many a time. We have Mitanni kings with Sanskrit names who ruled in Syria for centuries in the second millennium BC. The Gundestrup cauldron found in a peat bog in Denmark and estimated to have been made about 2000 years ago has images of Indian deities on it (including, most strikingly, that of a goddess worshiped by two elephants, Gajalakshmi), and thus may have been done by craftsmen of Indian origin, perhaps in Thrace. Trade between India and the West has been traced back to the third millennium BC. Such continuing interaction must have led to diffusion of art and culture.
