Astronomical clock in the Cathédrale Saint-Jean-Baptiste de Lyon in Lyon, France
The clock is one of the oldest in Europe and has an astrolabe that indicates the date, the position of the moon, the sun, and the earth, as well as the stars in the sky over Lyon. Created in the age of geocentrism, the sun is shown circling the earth. An astronomical clock was first documented in the cathedral in 1383. It was almost completely destroyed during a 1562 raid by the Baron of Adrets during the War of Religions, and in 1661 was reconstructed by master Lyonnais clockmaker Guillaume Nourrisson. During the French Revolution, all ornamentation that referenced royalty, like coats of arms and fleur-de-lys, was stripped from the clock. The last restoration was in 1954, when the clock’s perpetual calendar of 66 years was reset. It will be accurate until 2019.
