Aspergillum
（重定向自Aspergill）
An aspergillum (less commonly, aspergilium or aspergil) 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 in an aspersorium (holy water bucket, known to art historians as a situla).
