story of a global clock preserved into the medieval castle in Pesteil:
Giovanni Dondi (1318-1389) began fifteen years to build the technical masterpiece of its time, Astrarium (global clock), seen as a new wonder of the world. The clock showed the hour, day, month, the position of the Sun, the Moon, and the planets move marked the solstices and equinoxes. Unfortunately, the traces of the Astrarium is lost from the 16th century.
The story very precise and illustrated by Dondi construction has allowed specialists to reconstruct it. It no longer exists as such reproduction. After exposure in the most prestigious European museums Astrarium is exposed to Pesteils up to 31 December 2012.
The Astrarium is designed as a symbolic image of the cosmos: its seven sides represent the movements of the seven planets of antiquity (Moon, Sun, Venus, Mercury, Mars, Jupiter and Saturn), the theory of Ptolemy. They are arranged around a common engine watch, which is the driving force of the sky, in the daily movement.
