Book excerpt: The Image of Edessa, also later known as the Mandylion, was a relic of Christ, a cloth imprinted with his features which he had used to wipe his face, and subsequently used to cure King Agbar of Edessa, the first Christian ruler. This book collects and provides parallel translations of all the available written evidence for the image, along with detailed analysis of the history of the image. Guscin deftly seperates fact from legend, for while the story of King Agbar is certainly mythical, an image of some sort did definitely exist by the mid tenth century when it was translated to Constantinople.
