If you were wealthy and devout in 16th century Europe, one of the ultimate possessions was a prayer nut. These tiny wooden spheres were intricately carved boxes filled with religious scenes like the Crucifixion. Worn around the neck attached to a rosary or on the owners belt, it has been theorized that the outer carvings were inserted with aromatic plants and oils to add to the experience of owning one.

Prayer nuts are only a few inches across at most, with many even smaller.
