Historically the 'face of God' has been linked to the one of the greatest Catholic relics - the Veil of Veronica - a similar miraculous image, created on the day of Christ's crucifixion. When stumbling under the weight of the cross His brow was mopped by St Veronica - and an imprint of his face was left on her cloth. Throughout the middle ages this image was revered and worshipped by hundreds of thousands of pilgrims visiting Rome - and even created its own guild of artists, dedicated to selling reproductions of the image to pilgrims. But after the rebuilding of St Peter's basilica - designed as a new home for all the greatest Christian relics - suddenly and without explanation the veil disappeared from view was it lost, or even stolen? The Vatican claims to still have the veil but it is no longer on public view.
