The Church of the Nativity and Islamic Aniconism Lisa Mahoney DePaul University The twelfth-century mosaic interior of the Church of the Nativity in Bethlehem combines long stretches of text announcing Christian doctrine with images chronicling the life of Christ. It is a combination of forms without precedent and, accordingly, one that has consistently frustrated interpretation. This study offers a reading of these mosaics that takes account, on the one hand, of the church’s site—the location of the birth of Christ—and, on the other, of a historically and geographically specific anxiety— the contested orthodoxy of representations of Christ. I will argue that this anxiety was the result of the crusades and the contact between Latin Christians and Muslims they occasioned. Indeed, this program was begun and completed during the years that Bethlehem lay within the Franks’ Latin Kingdom of Jerusalem, and its church under the auspices of their ecclesiastics. This particular understanding of the mosaic program is confirmed by content reflecting theological decisions that argued for the necessity of representing the divine. And it was the perfect marriage of message and venue, for what took place in Bethlehem justified such representations, namely, the divine had taken human form, becoming perceivable and, ultimately, delineate-able. That this response was motivated by a context-specific encounter with Islam is suggested by contemporary Arab historians who complain about the Frankish use of images and ridicule their portrayals of Christ, by the employment in the Church of the Nativity of artistic patterns that echo walls of nearby mosques, and by the fact that Bethlehem was a site of communal (i.e. Christian and Muslim) worship. As such, the Church of the Nativity becomes our best evidence for real, substantial exchange between these cultures during the twelfth century. In its espousal of religious doctrine and aesthetic preference, it also becomes our clearest expression of the extent to which assertions of Frankish identity were bound to their immediate environment. For both of these reasons, the Church of the Nativity in Bethlehem promises to fundamentally affect our understanding of the form and function of the art of the crusades.
