Al-Jazari —- Writing...

  Al-Jazari was more of a practical engineer . “More interested in the craftsmanship necessary to construct the devices than in the technology which lay behind them” and his machines were usually “assembled by trial and error rather than by theoretical calculation. Some of Al-Jazari’s devices were inspired by devices such as one of his waterclocks which was based on that of a Pseudo-Archimedes. He was also inspired by Hibat Allah ibn al-Husayn (d. 1139) for musical automata. His full name was Badi Al-Zaman Abul-Ezz Ibn Ismail Ibn Al-Razzaz Al-Jazari and he lived in Diyar-Bakir (in Turkey) during the 6th century. The book he wrote contains instructions about the construction of 50  various machines .  These include water clocks. Al-Jazari also describes methods of construction and assembly in scrupulous detail of the fifty or so machines in it to enable future craftsmen to reconstruct them. And he was successful in that, for many of his devices were constructed following his instructions. The work by al-Jazari is also unique in the way that other writers often fail to give sufficient details, because amongst others, they are not craftsmen themselves, or kept their secrets, or if they were craftsmen, they could have been illiterate .Al-jazari made elephant clocks work with water power.  Moreover, Al-Jazari also explained how to transport water without manual labour. The six main categories are: water-clocks and candle-clocks, vessels and pitchers, vessels and basins for hand washing and surgical purposes, fountains and musical machines, water-raising machines; and miscell-aneous machines. He also invented a number of machines. Al-Jazari’s machines involved a large number of techniques and mechanisms. To the development of machines, such as axles, segmental gear wheel, flume-beam swape, crank as part of machine, suction pipes, regulators and control systems, accurate calibration of...
