Priyadarsika is a Sanskrit play attributed to king Harshavardhan. It was first translated into English by G. K. Nariman, A. V. Williams Jackson, and Charles J. Ogden in 1923. Ratnavali and Nagananda are other works of Harshavardhan. Harshavardhan was also a great lover of education and learning. Emperor Harshvardhana wrote all the three plays in the Sanskrit Language.
Seven major pillar edicts have been found at Lauriya-Araraj, Lauriya Nandangarh, Rampurva, Nigali Sagar, Sarnath, Topra, and Meerut. Ashokan pillars probably signify the axis of the world (axis mundi) that separated heaven and earth.
