The astronomical clock on the St-Paulus-Dom Cathedral in Münster, Germany ~ Unlike modern clocks, the Münster clock is divided into 24 hours, runs counterclockwise, and indicates hours and minutes simultaneously. Since the clock faces south, the hands thus follow the actual course of the sun. The main hand, decorated with a silver sun and a rainbow, indicates the time. Each red and white line within the circle of Roman numerals represents four minutes. Five minor hands indicate the position of the planets Jupiter, Mars, Venus, Saturn and Mercury, while a silver ball (half painted black) represents the moon in its phases.
