Permanent exhibition of Ancient Agora Museum

Terracotta water clock (klepsydra)

he klepsydra was a kind of hydraulic clock used for measuring speeches in the law courts of ancient Athens. It consisted of two vessels, one of which was placed at a higher level and was filled with water. The upper vessel had a small, bronze-lined outlet at the bottom. The speaker could continue speaking until the water was emptied into the vessel at the lower level.

The Agora vessel bears two inscriptions: υ, demonstrating that the klepsydra belonged to the Antiochis tribe, and XX.., indicating the capacity of the vessel, i.e. two choes (6.4 litres). This means that it took 6 minutes to empty.
