Jerzy Grotowski and the "Laboratory Theatre" presented his famous performance "The Constant Prince" to Iranian audiences in 1970 during the Shiraz Art Festival and in Teheran. Jerzy Grotowski travelled to Iran four times and his fifth journey, which was supposed to include "Apocalypsis Cum Figuris" as well as "Desert Project" had been thoroughly planned but never happened. Although Grotowski had not talked too much about his travels to Iran, his influence on Iranian artists during three generations is quite obvious. The author gathered many documents and conducted interviews for this in-depth study pursuing the fundamental questions of his research: How was Grotowski's work received in Iran and in what way did he influence theatre artists in Iran?
