An aspergillum is one of many items taken away from Gert Bigger’s road-side store (The Letter, the Witch, and the Ring, 173).


An aspergillum is a liturgical implement used to sprinkle holy water. It comes in two common forms: a brush that is dipped in the water and shaken, and a perforated ball at the end of a short handle. Some have sponges or internal reservoirs that dispense holy water when shaken, while others must periodically be dipped into a vessel carrying the holy water. The name derives from the Latin verb aspergere 'to sprinkle'.
