Clocks were not discovered they were invented.
A sand clock, commonly known as an hourglass, is a timekeeping device that measures the passage of time using the flow of sand from one bulb to another through a narrow neck. As the sand trickles down, it takes a specific amount of time to empty, allowing for measurement of intervals. Hourglasses have been used for centuries in various applications, including navigation and cooking, and are often appreciated for their aesthetic appeal as decorative items.
The sand clock or hourglass origins are unclear. It may have been the invention of a monk called Luitprand from Chartres, France. It was not until the fourteenth century that hourglasses started being seen. It is believed to have been invented in medieval Europe.

Clocks were not discovered they were invented.
A sand clock, also known as an hourglass, works by using two glass bulbs connected by a narrow neck filled with sand. As the sand flows from one bulb to the other, it measures a specific amount of time. The time it takes for all the sand to flow from one bulb to the other is typically consistent, making it a simple and reliable timekeeping device.
