It is believed that the shadow clock was originally made around 1500 B.C. It was the first predecessor of the clock that measured hours, although they were different numbers than those on modern clocks.
Shadow clocks were probably invented around 1500 BC. They were very similar to sundials, although they were much more precise.
Since the beginning of time
The primitive clock was invented by Henry de Wick in 1368.
The water clock was invented in Egypt in 200 BC.
The ancient civilization that is credited with inventing the clock is the Sumerians. They were thought to have created the clock's hour system with 24 hours and 60 minutes and the first clock prototypes known as sundials.
There were many important inventions that happened in the 1300â??s. In 1304, cannons and guns were invented in Europe and Arabia. In 1320, artificial Insemination for animal breeding, especially the breeding of horses, was invented in Arabia. In 1320, the hourglass for measuring time was invented in Europe. In 1325, the steel crossbow was invented in Europe. In 1350, the weight driven clock was invented in Europe. Finally, in 1396, metal movable type made from bronze was invented in Korea.
After the Sumerians, the Egyptians were the next to formally divide their day into parts something like hours. Slender, tapering, four-sided monuments (Obekusjs) were built as early as 3500 BC. Their moving shadows formed a kind of sundial, enabling citizens to partition the day into two parts by indicating noon. They also showed the year's longest and shortest days, when the shadow at noon was the shortest or longest of the year. Another Egyptian shadow clock or sundial, possibly the first portable timepiece, came into use around 1500 BC to measure the passage of 'hours'. This device divided a sunlit day into 10 parts, plus two 'twilight hours' in the morning and evening. When the long stem with five variably spaced marks was oriented east and west in the morning, an elevated crossbar on the east end cast a moving shadow over the marks. At noon, the device was turned in the opposite direction to measure the afternoon 'hours'. The Greeks invented a prototype of the alarm clock around 250 BC. They also built a water clock where clock where the raising waters would both keep time and eventually hit a mechanical bird that triggered an alarm. In 1908, the Westclox Clock Company is issued a patent for the Big Ben alarm clock. The outstanding feature on this clock is the bell-back, which completely envelopes the inner case back and is an integral part of the case. The bell-back provides loud alarm.
The `Gnomon` is the part of the shadow clock, or sun dial, that casts a shadow onto the face from the sun, so that the time can be read.
The shadow stick was invented to tell what time it is
Professor Farnsworth invented the death clock
1656Christiaan Huygens invented the pendulum clock and was the most accurate clock into the 1930s.
A shadow clock, or sundial, tells the time of day using the position of the Sun. The sun casts a shadow from the sundial's style onto a marked surface of hours.

the sterling silver clock was invented after the sundial

The common name for the timekeeping device sometimes known as a shadow clock is a sundial.
