Published on the occasion of Ali Kaaf's exhibition Ich bin ein Fremder. Zweifach Fremder at the Museum fur Islamische Kunst in the Pergamonmuseum Berlin, the catalogue documents the sculptural intervention created in the context of the Mschatta Facade. The eventful history of this icon of Islamic architectural culture is not only a metaphor for human existence, but also equally for the biography of the German-Syrian artist. The volume is augmented to include works on paper from past groups of works in the Rift series and Byzantine Corner, which illustrate Kaaf's intermedial working method. In subtle, abstract imagery, he works with layerings, incisions, burns, photography and digital image processing. Through the artistic exploration of breakages and reassemblages, complex spatial voids emerge that reflect both intercultural and internal processes.
