Veronica's Veil
The Holy Face is an "acheiropoieta" icon, that is to say, "not made by human hand"; the image was created miraculously when Veronica used her veil to dry Christ's face on his way to Calvary. The veil of Manoppello, kept in the shrine of that name in Italy, is supposed to be that image of the Holy Face. The likeness served as the model for later representations. Benedict XVI visited Manoppello during his pontificate.
