Good quality of Sanskrit literature was produced in India from the second century AD to the fourth and fifth century AD. The Guptas made Sanskrit their court language. Kalidasa, the greatest poet-dramatist, enriched the Sanskrit language. His plays Abhijnana Shakuntalam, Vikramorvashi and Malavikagnimitra, are gems of Sanskrit literature. Some other significant authors of this period were Vishkhadatta who wrote Mudra Rakshasa and Shudraka who wrote Mrichhakatikam. Panchatantra, a wonderful collection of animal fables, was also written during this period.
