Nocturnal clock
The nocturnal clock is a fascinating baroque masterpiece, made between 1730 and 1740 by Jakob Bentele, a clock-maker from the Allgäu region of Germany. It was designed by Bernard Stuart, a Scottish ecclesiastic.
The table clock’s special feature is its night function. In the back, there is a cavity for a light source, such as a candle or an oil lamp; this casts the shadow of the hands on to the dial, which is made of precious French silk. Thus one could read the time in the dark.
Nocturnal clocks were popular from the 17th century, particularly in Italy. The silk dial remained popular until well into the 19th century, even though it was highly flammable. For safety reasons, it was eventually replaced by other materials.
Salzburg Prince-Archbishop Leopold Firmian had a keen interest in astronomy and horology. His passion for these subjects is reflected by the many chronometers, clocks and technical marvels he ordered to be crafted.
