The Clepsydra of Karnak at the National Museum of Egyptian Civilization

In this episode, we’ll be visiting the ancient Egyptian Clepsydra of Karnak at the National Museum of Egyptian Civilization in Cairo. Welcome to Art, Culture & Books with me, Anthony King.

This incredible alabaster Clepsydra, from 1391-1353 BC is thought to be the oldest ever found in history. The Karnak Clepsydra features 12 intricately carved columns, each accompanied by corresponding holes representing the hours of the night. A minute hole at the centre of the base allowed water to flow, emerging outside beneath the depiction of a seated baboon. Its design prioritized independence from weather conditions, ensuring consistent timekeeping even with poor visibility of the sun or stars.

Determining the time involved observing the water level within the basin and referencing the nearest hole. The water’s level in the vessel served as the indicator of time. Remarkably, the progression of hours varied based on the month and whether it was daytime or night time. This is impressive technology. It’s material also allows light through which gives it a very magical quality. Out of all the items I saw in Egypt, including even the Pyramids – this one is near the top of the list.
