The subject of this lecture is horology, the science of measuring time. The
measurement of time
has come a long way since ancient time. It began with such devices as the sundial, where the position of the sun’ s shadow marked the hour. Daylight was divided into 12
temporary
hours, which were longer in the summer and shorter in the winter, simply because the amount of daylight changes with the season.
The earliest sundial we know comes from Egypt, which was made of stones. Sundials were used through the classical world, and with time, evolved into
more elaborate devices
that could take into account seasonal changes and
geographical
positioning and reflect the hours accurately. This was quite an achievement in technology. Today, sundials can be seen as decorative pieces in many gardens.
In the 11th century, the Chinese invented the first mechanical clocks. They were large and expensive, and certainly not
intended for
individuals. However, this is the type of clocks we are familiar with today. There have been many developments in clocks and watches since then, and they’ ve been greatly improved. However, if your clock or watch makes a ticking sound, then it could well be based on the mechanical movements the Chinese developed a thousand years ago!
