For centuries, liturgical, large-scale windows metaphorically shielded the sacred from the profane, embued light with spiritual presence, and literally illuminated divine messages. During war reparations, Germany’s shattered postwar outlook challenged a new generation of artists with the daunting task of establishing new religious symbols to speak authentically into a deeply crushed, cynical national conscience. Subsequently, while Germany’s parishes dwindled, glass artists readjusted to a new clientele: dutiful streams of international tourists whose entry fees bankrolled Germany’s historical churches. This original research explores the unique liturgical iconography developed to address a nation’s broken faith, and a global audience’s comprehension in a secularized culture.
