The Natyashastra states that, the sutradhara should be a master of sciences and arts, know countries and costumes prevalent in them. A sutradhara should be well versed in language, the science of dramaturgy and versification. He should have good knowledge of music, musical instruments, political science, geography, astrology, anatomy, history, law, emotions and sentiments. He should be able to foresee the purport of his own exposition. In addition to all these qualities, a sutradhara should have excellent memory and intellect, and has to be grave and generous. He should be in good health, sweet tempered, self controlled, of a forgiving nature, righteous, not avaricious, truthful and impartial. The sutradhara is the instructor of the actors. In the Uttararamacarita, Bharata is called tauryatrika sutradhara, professor of the three kinds of sangita (instrumental music, song and dance). Thus the sutradhara was an important dramatic personage, controlling the whole company, assuming different roles, sometimes arranging the scenes, sometimes directing the actors and sometimes himself taking an important role in the plays.
According to the dramatic treatises, the sutradhara had two associates, the sthapaka and the pariparsvika. Attributes wise, the sthapaka resembles the sutradhara. Immediately after the preliminaries, another person, similar to the sutradhara in appearance and qualities is to enter and introduce the play, a function which gives him the designation of the introducer (sthapaka). He does not, however, figure in any of the extant dramas and so the duties assigned by the dissertation to the sthapaka must have all been performed by the sutradhara himself.
The Natyashastra prescribes that the qualities and qualification of the pariparsvika is second only to those of the sutradhara. . He is of middle type, of good form, clever and an expert in the performance of his duties. He has full knowledge of instruments. He is an assistant of the sutradhara or the narrator. He come into sight in the prologues of many plays and acts the parts of persons of rank. He receives the sutradhara's orders, passes them on to other actors and directs the chorus. The Natyashastra also refers to some acaryas, expert in preparing materials required for the stage and proficient in directing actors and actresses.
The mukutakara makes crown for the characters with the help of different materials. Various kinds of head dresses are also prepared by the mukutakara. Ornaments are made by the abharanaakrit and garlands by malyakrit. The vesakara prepares dresses which are dyed by the rajaka. The karuka prepares things out of lac, stone, iron and wood. He is an artisan who prepares different items of stage paraphernalia. The kusilava is an expert in the arrangement of musical instruments and also in playing them. The natyakara leads the characters in a play by directing them in the representation of feelings. The nata is the performer of natya expert in using the four kinds of musical instruments. He is called nata because he represents and imitates the actions of men. He is an authority in the demonstration of sentiments, feelings and bravery.
The natakiya is a beautiful woman who can sing and has the ability to stir up sentiments. She is familiar with the diverse kinds of musical instruments and has understanding of rhythm and melody. The taurika is the head of warriors and trumpeters, a professional in playing all musical instruments. Thus artisans are named according to the duties they are called upon to perform.
