The term Indian classical drama refers to the tradition of dramatic literature and performance in ancient India. The roots of drama in the Indian subcontinent can be traced back to the Rigveda (1200-1500 BCE), which contains a number of hymns in the form of dialogues, or even scenes, as well as hymns that make use of other literary forms such as animal fables However, Indian drama begins its classical stage in the 3rd-4th century BCE with the composition of the Nātyaśāstra (lit. The Science of Drama). Indian classical drama is regarded as the highest achievement of Sanskrit literature.
