There is a Nala in Mahabharata.
Vrihadaswa said, "There was a king named Nala, the son of Virasena. And he was strong, and handsome, and well-versed in (the knowledge of) horses, and possessed of every desirable accomplishment. And he was at the head of all the kings, even like the lord of the celestials. And exalted over all, he resembled the sun in glory. And he was the king of the Nishadhas, intent on the welfare of the Brahmanas, versed in the Vedas, and possessed of heroism...
There is another Nala in Ramayana too
The brilliant Gandhamaadana is the son of Kubera, while the divine architect Vishvakarma procreated the great monkey called Nala.
Is there any meaning to the name Nala?
