The astronomical clock of Bourges Cathedral was designed by Jean Fusoris and first installed in November 1424, during the reign of Charles VII, when the royal court was based in Bourges, for the occasion of the baptism of his son the Dauphin (the future Louis XI). It has two dials, the upper one added in the 19th century showing the time, the lower one showing the hour, the moon phase and age, and the position of the sun in the zodiac.
