Since the first publication about it in 1901, this unique wooden relief has been attributed to the Coptic maker because it was discovered in Egypt. The precise meaning of its richly detailed and impressive imagery, however, had remained shrouded in obscurity. The iconographic and stylistic analysis contained in this volume draws on comparative studies of material artifacts to reveal that the wooden relief belongs to Western Roman art of the fifth century. The relief portrays the suppression of the usurpation of John and his Hunnic cavalry troops outside the city gates of Ravenna by the Roman legionaries of Galla Placidia in the summer of 425 A.D. This historical revision places the relief in a new research context.
