Rainer von Hessen and Niki de Saint Phalle met after he saw a photo of HON, the 1966 installation for Moderna Museet Stockholm, in a German magazine. Their collaboration began when Saint Phalle first designed the costumes and sets to Aristhophanes’s LYSISTRATA, directed by Hessen (then known under the stage name Diez). Thereafter, Hessen co-authored and directed her play ICH, which was performed at the Staatstheater Kassel in 1968.
