Bits of late Roman coinage, the mutilated torso of a marble Venus, blue debris from an early medieval glassworks, and the powder rasped from the reputed tomb of Mary Magdalene - these tantalizing mementos of human history found scattered throughout the landscape of southeastern France are the points of departure for Gustaf Sobin's lyrical narrative. A companion volume to his acclaimed "Luminous Debris", "Ladder of Shadows" picks up where the former left off: with late antiquity, covering a period from roughly the third to the thirteenth century. Here Sobin offers brilliant readings of late Roman and early Christian ruins in his adopted region of Provence, sifting through iconographic, architectural, and sacramental vestiges to shed light on nothing less than the existential itself.
