"But among the rest, there was also another of the minsters, which was called the Church of my Lady Saint Mary of Blachernae, within which was the shroud wherein Our Lord was wrapped. And on every Friday that shroud did raise itself upright, so that the form of Our Lord could clearly be seen. And none knows - neither Greek nor Frank - what became of that shroud when the city was taken".<quoted text>
Most evidence shows the Shroud to be a fraud. None shows it to be a burial cloth of Jesus.
