Donald Hill, “Mechanical Engineering in the Medieval Near East”, Scientific American, May 1991, pp. 64-9. Al-Jazari’s book contains 50 mechanical devices, along with minute instructions on how to construct them, providing an invaluable contribution to the history of engineering. The devices are grouped into six categories: Ananda K. Kumarasvami, The Treatise of Al-Jazari on Automata: Leaves from a Manuscript of the Kitab fi Ma’arifat al-Hiyal al-Handasiya in the Museum of Fine Arts, Boston, and Elsewhere. Boston: Museum of Fine Arts, 1924 (Communications to the trustees, VI). The above will occur at every half hour for all the hours of the day, and will continue throughout the night, but with the addition of a lit candle behind the crescent disc. Thus, as the hours of the night go by, the crescent disc will rotate to reveal light through the roundels. How does it Work?

There is a weight at the other end of the rope, which is lighter than the float, and this keeps the rope taut at all times. The peahen is initially facing to the right, and the pulley system will turn the peahen 180 o to its left in half-an-hour. The main gear wheel is part of a pulley system that turns the crescent disc behind the roundels at the top.
