Kaspar is the most extraordinary and impressive play to date by Peter Handke. First staged in Germany in 1968, it was hailed by Max Frisch as 'the play of the decade'. The central character is Kaspar, a figure based on the historical Kaspar Hauser, an autistic adolescent, who is guided and taught until he speaks 'normally', by the voices of unseen prompters. As the words begin to coincide with reality, Kaspar learns to manipulate both. In the latter part of the play the tension between the individual and 'the others' is further expressed through the image of the original Kaspar surrounded by a host of identical 'Kaspars'.

Having chosen language as a vehicle, Peter Handke explores it as a means of oppression - a means of creating artificial uniformity by teaching people to comprehend the world only in terms of the speech patterns they are given.
