A monstrance is a vessel used in the Roman Catholic Church to display the consecrated bread; clocks are known made in a shape similar to that of this receptacle. The movement is placed in a drum supported by a stand and is of the type usually found as a horizontal table clock. Astronomical work is normally provided and the quality of these clocks altogether is high. The period of manufacture was from the mid 16th to the mid 17th century, and Augsberg was probably the origin of the type.
