In 1995 Gittoes won the Blake Prize for religious art a second time, for one of several versions of "The Preacher", a powerful image of a preacher trying to bring calm to the people around him – and to himself – amidst the chaos and carnage of Kibeho. In 1997 he set up an installation of Rwanda works at "documenta X" in Kassel, Germany. It included ten large confronting 3 v 1.5 m paintings, employing what Gavin Fry describes as “a violent, gut-wrenching expressionism”, to depict the depths of violence and depravity reached at Kibeho; the floor was covered in rags, clothes, and plastic containers. In 2014 he returned yet again to the Rwanda material with a series of “synthages”, combinations of photograph, drawing and painting developed in collaboration with printer John Wesley Mannion.
