It was no longer a question for Seleucus to despise the alliance of such a powerful monarch: he left his territories beyond the Indus and bestowed on her the hand of a Greek princess. From that moment on, India entered the orbit of the great empires of time; its capital, situated in Pataliputra or Magadha, was for many decades the center of a Greek embassy which Ambassador Magastenio illustrated, and whose information is precious, though secondhand.
