Prague Astronomical Clock

This guide to the Prague Astronomical Clock takes apart a four-hundred-year-old story: that a blinded clockmaker named Hanus sabotaged his own masterpiece rather than let rival cities copy it. It follows the historian who traced the tale to a case of mistaken identity, and the real record, a mechanism first built in 1410 by a clockmaker named Mikulas of Kadan working with a university astronomer. Watch for the top of the hour, when a skeleton representing Death rings its bell and the twelve apostles rotate past overhead.
