Astronomical Clock

March 6, 2006

< < previous | next > >

Prague's Town Hall Clock measures the movement of the sun and moon through the 12 signs of the zodiac, as well as the day's time in three systems -- Old Bohemian time (24 hours, starting at sunset), Babylonian time (12 hours of daylight, of varying length from summer to winter), and time as we know it. Mechanical apostles parade past on the hour -- so I'm told, I couldn't stick around as I had a CIO to interview.
