Manuscript of Ismail al-Jazarī's Ingenious Mechanical Devices (ca. 17th century)

Summary

Al-Jazarī, who passed away in 1206, served as the chief engineer for the court of the Artuqids in Diyarbakir. His Book of Knowledge of Ingenious Mechanical Devices lives up to its name, detailing lock-like devices for raising water, sophisticated zodiac clocks, avian automata able to produce song, and a showering system for King Salih, who “disliked a servant or slave girl pouring water onto his hands for him”. He invented bloodletting technologies, mischievous fountains, segmental gears, and a chest (sundūq) that featured a security system with four combination dials — presumably a safe for storing valued possessions — and has been subsequently dubbed “the father of robotics”, due to his creation of a life-like butler who could offer guests a hand towel after their ablutions. Al-Jazarī’s contemporaries already recognized his eminence as an engineer, referring to him as unique and unrivaled, learned and worthy. He stood on the shoulders of Persian, Greek, Indian, and Chinese precursors, while Renaissance inventors, in turn, stood on his.
