Foot reliquary from the Basel Minster treasury, 1450, silver, copper, gold-plated, mother of pearl, enamel, pearls, gemstones and glass.

"It is shaped like a foot to reflect its contents– what were believed to be the foot bones of a little boy murdered in Bethlehem on the orders of King Herod.
While this might strike modern observers as creepy, believers regarded such relics as objects of religious veneration. A window of polished rock crystal allowed the relics to be viewed by the public on feast days, and churchgoers hoped that a glimpse of them would allow them to obtain divine aid."
