Barrie Schwortz was the documenting photographer for the Shroud of Turin research project in 1978, an in-depth examination of what many people believe to be the burial cloth of Jesus.
Missing Years of the Holy Shroud
The Holy Shroud disappears from Constantinople during the Crusade in 1204. Two elements confirms the presence of the Shroud in Athens since 1205 when, after the splitting up of the Byzantine Empire, Othon de La Roche, baron of Ray-sur-Saône, became Lord of Athens. Many tracks suggest that, after 1225, Othon came back in France with the Shroud. After his death, in 1234, the Shroud remain in Ray-sur-Saône family hands until Its handing over to the de Vergy family. Thanks to Jeanne de Vergy, related in the fifthgeneration with Othon, the Shroud would have been shown in public in Lirey.
Even if it is accepted that the Turin Shroud and the cloth observed in Constantinople by the crusader knight Robert de Clari  (“Among other astonishing things there is a church called Saint Mary of Blacherne, where there is the sydoines (Shroud), in which Our Lord Jesus was wrapped and that every Holy Friday is lifted up vertically, so that the shape of Our Lord could be seen very well” .) were one and the same object, there still difficulties remain in establishing a chronology for the relic during the historical gap of more or less one hundred and fifty years, from 1204 in Constantinople to its re-appearance in Lirey in the fourteenth century. Different hypotheses have been formulated about these“Missing Years” . In this paper, the author presents an additional hypothesis in an attempt to explain that intervening period during which the Shroud completely disappeared.
