| In addition to the Egyptians (see also The ancient egyptians), many other people experimented with water
clocks and some interesting variations sprouted forth. For example, in some cases a float
was connected to a wheel and, as the float changed its level, the wheel turned to indicate
the hour on a dial. |

Water clocks were also a standard means of keeping time in Korea
as early as the "Three Kingdoms" period, and it was here that one of the
first known automatic water clocks was devised in 1434. This clock was called Chagyongnu,
which literally translates as "self-striking water clock." When the
water reached a certain level, a trigger device released a metal ball which rolled down a
chute into a metal drum to "gong the hour." |
