Münster Cathedral: Rulers of the Hours

Rulers of the Hours

Detail of Münster Cathedral's magnificent astronomical clock, made in 1540-43. Running vertically on either side of the clock are boards painted with the gods/planets that rule the day; these change at midnight. They ascend on the right and descend on the left and the ruler of the first hour (labeled IN 1 HO REGIT) is shown on the bottom right. This is the ruler of the day, after which the day is named.
