Once again the word of the day comes from THE DEATH OF NOAH GLASS by Gail Jones.
Acheiropoieta — also called Icons Made Without Hands — are Christian icons which are said to have come into existence miraculously; not created by a human. Invariably these are images of Jesus or the Virgin Mary. The most notable examples that are credited by tradition among the faithful are, in the Eastern church the Mandylion, also known as the Image of Edessa, and the Hodegetria, and several Russian icons, and in the West the Shroud of Turin, Veil of Veronica, Our Lady of Guadalupe, and Manoppello Image. The term is also used of icons that are only regarded as normal human copies of a miraculously created original archetype.
