A. Lange & Söhne Saxonia Annual Calendar
The development of the A. Lange & Söhne Saxonia Annual Calendar was driven by the desire to achieve clarity and harmony in the arrangement of its many displays. In this scenogra-phy of the planets that orbit the earth, as envisaged by Tycho Brahe, the watch occupies the position of the sun. The Danish astronomer, too, considered the earth to be the rigid centre of the cosmos, around which the sun, the moon, and the stars move along their orbits. However, he believed that all the other planets, the earth being the exception, orbited the sun.
