Ancient Egypt and Sudan

    Fragment of a basalt water clock

    Said to be from Tell el-Yahudiya, Egypt
    Macedonian Dynasty, around 320 BC

    With the names of Philip Arridaeus

    On the death of Alexander the Great in 323 BC, the throne of Macedon passed to his half-brother Philip Arridaeus (323-317 BC). He left several monuments in Egypt, of which the most visited is the sanctuary of the Temple of Amun at Karnak. This water-clock is another object which bears his name.

    Water-clocks, which measured time by the gradual evacuation of their contents through a hole at the base, were a way of keeping track of the passing of the 'hours' in which Egyptians divided the day and night.

    Both day and night were divided into twelve hours each. However, as the length of day and night varied with the seasons, it was necessary to calibrate the clocks each month. For example, the twelve daylight hours would each have to be shorter in the winter months, to fit them all between dawn and dusk.

    The gods Min and Sekhmet shown with the king represent the fourth and fifth months. The 'hours' are marked on this clock by small holes bored into the stone.

    The clock continued to be used into the Roman period (after 30 BC) as can be seen by some Latin letters indicating months on the top.
