He has written two plays for the theatre. The first was a full-length shadow-puppet play "The Tragical History of Jackson Pollock, Abstract Expressionist" (1999), in English, of which he also designed and directed the Athens performance. In this play, Doxiadis realized some of his views on “epic theatre”, in other words a theatre based on storytelling. His second play, "Incompleteness" (2005), is an imaginary account of the last seventeen days in the life of the great logician Kurt Gödel, which Gödel spent in a Princeton, New Jersey, hospital, refusing to eat out of fear that he was being poisoned. The play was staged in Athens, in 2006, as Dekati Evdomi Nyhta (Seventeenth Night) with the actor Yorgos Kotanidis in the role of Kurt Gödel.
