Kalidasa, one of the chief figures in classic Sanskrit literature was also a dramatist and poet. He was one of the Navratnas (9 gems or the most accomplished men of their times) at the court of Chandragupta Vikramaditya. Kalidasa's works include plays, Epics and lyrics. His play 'Abhinjnana Sakunthalam' (Recognition of Sakunthala) is the most well-known of all his works and it has been translated into various languages of the world. In all, 7 works of Kalidasa are available today. They are: 'Malavikagnimitra', 'Vikramorvasiyam' and 'Abhijnana Sakunthalam' (plays); 'Raghu Vansa' and 'Kumara Sambhavam' (Epics); 'Meghdoot' and 'Ritu Samhara' (lyrics).
