 Major works set against the backdrop of the Second World War are "De Aanslag" (The Assault), "Het stenen bruidsbed", and "Siegfried".Mulisch often incorporated ancient legends or myths in his writings, drawing on Greek mythology (e.g.in "De Elementen"), Jewish mysticism (in "De ontdekking van de Hemel" and "De Procedure"), well known urban legends and politics (Mulisch was politically left-wing, once signing a book "dedicated in admiration" to Fidel Castro).
