Biblical Magi
On the northwest wall of the north transept in a medieval clock, dating to the 14th century. The clock is in the form of the façade of a church, with elaborate tracery, gables and carved angels. On the hour, a series of figures, representing the seasons, the phases of the moon, and the Biblical Magi appear and disappear from the doors on the face of the clock. It is one of the oldest examples of this kind of mechanical clock.
