Shadow play which is also known as shadow puppetry is an ancient form of storytelling and entertainment which uses flat articulated cut-out figures (shadow puppets) which are held between a source of light and a translucent screen or scrim. The cut-out shapes of the puppets sometimes include translucent color or other types of detailing. Various effects can be achieved by moving both the puppets and the light source. A talented puppeteer can make the figures appear to walk, dance, fight, nod and laugh.
Shadow play is popular in various cultures; currently there are more than 20 countries known to have shadow show troupes. Shadow play is an old tradition and it has a long history in Southeast Asia; especially in Indonesia, Malaysia, Thailand and Cambodia. It is also considered as an ancient art in other parts of Asia such as in China, India and Nepal. It is also known in the West from Turkey, Greece to France. It is a popular form of entertainment for both children and adults in many countries around the world.
Shadow play probably developed from "par" shows with narrative scenes painted on a large cloth and the story further related through song and chant. As the shows were mostly performed at night the par was illuminated with an oil lamp. Similar storytelling with pictures may date back to the Harappa civilization (4500 BCE - 1300 BCE). By at least around 200 BCE the figures on cloth seem to have been replaced with puppetry in Indian "tholu bomalatta" shows. These are performed behind a thin screen with flat, jointed puppets made of colorfully painted transparent leather. The puppets are held close to the screen and lit from behind, while hands and arms are manipulated with attached canes and lower legs swinging freely from the knee.
Recent studies relate shadow puppet making with other pictorial traditions in India, such as temple mural painting, loose-leaf folio paintings, and the narrative paintings used by storytellers to enhance the connection with the audience. This also shows that rather than a minor and folk tradition, shadow puppetry in India actually followed the precepts of painting and performance treaties similarly to the classical arts patronised by the royal courts.
