Water Clocks
There is also evidence for the use of water clocks in anciet Egypt. An early Egyptian water clock dating to about 1500 BC was found among other items in the tomb of the pharaoh Amenhotep I; their creation is attributed to an inventor named Amenemhat. Early water clocks were usually bowl-shaped with a small hole at the bottom and markings on the inside at even intervals. The bowl was floated on water and allowed to fill such that the rising water indicated the passage of a set number of hours. Water clocks were useful for priests as they could accurately measure time in all seasons and independently of the sun, which was important for determining when to perform religious ceremonies and rituals.

Famous quotes containing the words water and/or clocks:
“The dominant and most deep-dyed trait of the journalist is his timorousness. Where the novelist fearlessly plunges into the water of self-exposure, the journalist stands trembling on the shore in his beach robe.... The journalist confines himself to the clean, gentlemanly work of exposing the griefs and shames of others.”
—Janet Malcolm (b. 1934)
“all the clocks in the city
Began to whirr and chime:
“O let not Time deceive you,
You cannot conquer Time.”
—W.H. (Wystan Hugh)
