The German (Potsdam) committee of the Corpus Vitrearum has just published a superb two-volume study of the medieval stained glass of Berlin and the surrounding state of Brandenburg. Entitled Die mittelalterlichen Glasmalereien in Berlin und Brandenburg, the book covers sites such as the Cathedral of St Peter and St Paul at Brandenburg an der Havel, St Mary’s at Frankfurt (Oder), the pilgrimage church of St Nicholas at Bad Wilsnack [Fig. 3], and the holdings of the Berlin Applied Arts Museum, one of the most important collections of medieval stained glass in Germany. It includes contributions from Ute Bednarz, Eva Fitz, Peter Knüvener, Frank Martin, Markus Leo Mock, Götz J. Pfeiffer and Martina Voigt. A major review of this important publication will appear in a future issue of Vidimus.
