The Sanskrit term dhruva nakshatra (ध्रुव नक्षत्र, "polar star") has been used for Pole Star in the Mahabharata, personified as son of Uttānapāda and grandson of Manu, even though Polaris at the likely period of the recension of the text of the Mahabharata was still several degrees away from the celestial pole.[4][5]
