Egipski zegar wodny z pawianem, 664–30 rok przed naszą erą.
"This piece is considered to be a model of a water clock. Water within could drain from a hole between the baboons legs over a measured time. This object was likely a temple offering to the god Thoth in his role as overseer of knowledge and measurement."
The invention of the water clock “ca. 1530 B.C., is credited to a priest-scientist named Amenemhet,” and it was an important part of determining time in ancient Egypt (Fleming, 1986: 64–65). According to Cotterell, “the priests needed to tell the time accurately during the night so that the temple rites and sacrifices could be performed at the right hour” (1986: 32). Water clocks were often a better option than sundials because they did not depend on the weather and could be used in darkness, since the passing hours were determined by water flowing out of the earthenware vessel rather than shadows cast by the sun (Cotterell, 1986; Fleming, 1986). Though the draining of water is similar in concept to the large cylindrical clepsydrae used in ancient Egypt and Greece, the rectangular inflow styles likely did not have hour measurements inscribed on the inside (Pogo, 1936).
