The Banū Mūsā brothers https://en.wikipedia.org/wiki/Ban%C5%AB_M%C5%ABs%C4%81 https://en.wikipedia.org/wiki/Ban%C5%AB_M%C5%ABs%C4%81 "The most popular of their publications was the Kitāb al-Ḥiyal (The Tricks Book), which was mostly the work of Aḥmad, the middle brother, was a book filled with one hundred mechanical devices. There were some real practical inventions in the book including a lamp that would mechanically dim, alternating fountains, and a clamshell grab. Eighty of these devices were described as "trick vessels" that showed a real mastery of mechanics, with a real focus on the use of light pressure. Some of the devices seem to be replications of earlier Greek works, but the rest were much more advanced than what the Greeks had done."
