| Description |
English: Su Song's Water Clock (???).
This picture is a scaled model of Su Song's water-powered clock tower. The original clock tower was 35 feet tall. It was a 3 story tower with an armillary sphere on the roof, and a celestial globe on the third floor. This picture was taken in July 2004 from an exhibition at Chabot Space & Science Centre in Oakland, California. The quality of the picture is not ideal because flash photography was not allowed. |
