The oldest part of the Prague Astronomical Clock, the mechanical clock and astronomical dial, dates from 1410 when it was made by clockmaker Mikuláš of Kadaň and Jan Šindel, then later a professor of mathematics and astronomy at Charles University. The first recorded mention of the clock was on 9 October 1410.

Calendar dial face made by Josef Mánes (1865)
The four figures flanking the clock are set in motion on the hour, and represent four things that were despised at the time of the clock's making. From left to right in the photographs, the first is Vanity, represented by a figure admiring himself in a mirror. Next, the miser holding a bag of gold represents greed or usury. Across the clock stands Death, a skeleton that strikes the time upon the hour. Finally, there is a Turkish figure representing lust and earthly pleasures. On the hour, the skeleton rings the bell and immediately all other figures shake their heads side to side, signifying their unreadiness "to go".
