Sakuntala was a nymph who was the daughter of Vrishanaswa by the nymph Menaka. She was born and left in the forest, where she was nourished by birds until found  by the sage Kanwa. She was brought up by this sage in his hermitage as  his daughter, and is often called his daughter. The loves, marriage, separation,  and re-union of Sakuntala and King Dushyanta are the subject of the celebrated drama Sakuntala. 1.
