The Natyashastra by Bharata Muni depicts the mature form of a classical theatre of ancient India. Natyashastra is the most detail and elaborate of all treatises on dramatic criticism and acting ever written in any language. Bharata Muni here have discussed about a variety of topics in relation to the stage. The topics discussed in this work are: Mythical origin of theatre, its coming down to earth; construction of a play house, a stage, a tiring room and auditorium etc., ceremonies relating to the construction, preliminaries to a dramatic performance (ceremonies including songs, chants dances and instrumental music), choreographic elements (dance, gestures and movements of different parts of the body) and body in some conventional postures, costumes and make-up, classification of plays analysis of their structure, poetic aspects of plays and figures of speech in them, theory of music, metres of songs, chants, elocution, modes of playing instruments (Veena, flutes and drums) and Talas (time measure) to be observed during songs and playing of instruments, Roles and characters in plays (their classification, description and training of actors and actresses, members of theatrical troupes, and qualification of an ideal stage manager), criticism of a dramatic performance. Bharata Muni thus laid the foundation of the classical Theatre by composing the Natysastra.Types of PlayhouseIn Natysastra Bharata has discussed about three types of playhouse, oblong, square and triangular. These three have been further divided into large, medium and small. These measurements could be in terms of dandas or cubits, naturally giving us eighteen different dimensions of playhouse.According to Natyasastra a regular theatre consists of three parts, the tiring room, the stage and the auditorium. The stage is required to have two Mattavaranis on the two sides. There was existence of permanent and temporary theatres in ancient India.
