The original use and arrangement of these fourteen ivories of the So-called Grado Chair with scenes from the life of Christ, depictions of saints, and of Saint Mark as first bishop of Alexandria remain uncertain. They may have been part of a liturgical throne given by Emperor Heraclius (r. 610–41) to Grado, Italy, after his successful re-conquest of Egypt. On this plaque, the Nativity is set before the walls of an elaborate city, possibly Bethlehem. The Christ child’s manger resembles an altar.
