The History of The Arabic Automata

The Arabic Automata

After the fall of the Western Roman Empire in the end of 5th century, the western and central part of Europe was swept down by many barbarian tribes and fell into the so called Dark Ages for some five centuries. During this time, the centers of world’s art and science moved to the East — to the eastern Roman Empire, which managed to survive the attacks, China and India, where great civilizations grew and spread, and into the mighty Arabic empire.

The period 9th-13th century was a full of extraordinary activity in science and technology in the Arabic empire. In 8th century the Abbasid dynasty took over rule of the vast Muslim world and moved the capital to the newly-founded city of Baghdad. Over the next five centuries, the city would become the world’s center of education and culture.

The Abbasid Caliphs were very interested in clocks and ingenious devices. There are many recorded contributions to the area of automatic machines from this period. The Arabic automata technology, as well as many other arabic technologies, had as a basis the Greek automata tradition of mainly two engineers, namely Philon of Byzantion and Heron of Alexandria

Several Arabic scientists are known to had been worked in the field of automata, e.g. Abu Musa Jabir ibn Hayyan from 8th century, the so called pseudo-Archimedes and Banu Musa brothers (3 Persian scholars from Baghdad) from 9th century, Al-Muradi and Al-Khazini from 11th century, Hibat Allah ibn al-Husayn and Ridwan Al-Khurasami from 12th century, but the most important work in this field is al-Jamiʿ bayn al-ʿilm wa ʿamal, al-nafiʿ fi sinaʿat al-hiyal (the book of knowledge of ingenious mechanical devices) of Al-Jazari from 1206.

Al-Jazari (his full name is Al-Shaykh Ra’is al-A’mal Badi’ al-Zaman Abu al-‘Izz ibn Isma’il ibn al-Razzaz al-Jazari) was an influential scholar and engineer, who lived in the second half of 12th and in the beginning of 13th century. He died in the beginning of 1206, just few months after he had completed his famous book in January, 1206.

Al-Jazari was in service at the court of three Artuqid rulers since 1174 until his death, and the above-mentioned book was created in the period 1198-1206 in response to the request of Nasir al-Din Mahmud (1200-1222).

According to his name, Al-Jazari was born in Al-Jazira (the traditional Arabic name for what was northern Mesopotamia and what is now northwestern Iraq and northeastern Syria, between the Tigris and the Euphrates).

Like his father and his brother before him, he served as an engineer at the Artuklu Palace, the residence of the Diyarbakır branch of the Turkish Artuqid dynasty, which ruled across eastern Anatolia as vassals of the Zangid rulers of Mosul.

The book of Al-Jazari describes in detail fifty devices, which are grouped into six categories:
1. Ten water and candle clocks
2. Ten vessels and figures suited for drinking sessions
3. Ten pitchers and basins for phlebotomy and washing before prayers
4. Ten fountains that change their shape alternately, and machines for the perpetual flute
5. Five water raising machines
6. Five miscellaneous devices

The earliest copy of the book, survived until now (from 1206) is a fine manuscript with excellent illustrations. Each device is described in a simple and easy to understand Arabic, and each is accompanied by a general drawing. For the complicated devices the author gave detailed drawings for the components of the device or for subassemblies so that the operation can be understood. There are a total of 174 drawings in the book.

The automata in the book of Al-Jazari included:

  1. An automated girl serving drinks (see image above)
  2. An automated moving peacocks driven by hydropower
  3. Automatic gates, which were driven by hydropower
  4. Several other automata, including automatic machines, home appliances (table devices), and musical automata powered by water

Al-Jazari also invented water wheels with cams on their axle used to operate automata.

The humanoid automata of a girl that could serve water, tea or drinks, shown in the upper image, is very interesting. The drink was stored in a tank with a reservoir from which the drink drips into a bucket and, after seven minutes, into a cup, after which the waitress appears out of an automatic door serving the drink.

Al-Jazari described a hand washing automaton (see image below), incorporating a flush mechanism, now used in modern flush toilets. It features a girl automaton standing by a basin filled with water. When the user pulls the lever, the water drains and the girl refills the basin.

Al-Jazari’s peacock fountain was a more sophisticated hand washing device, featuring humanoid automata as servants which offer soap and towels. Pulling a plug on the peacock’s tail releases water out of the beak, and as the dirty water from the basin fills the hollow base a float rises and actuates a linkage, which makes a servant figure appear from behind a door under the peacock and offer soap. When more water is used, a second float at a higher level trips and causes the appearance of a second servant figure, this time with a towel!

Al-Jazari described also a musical automaton (see the image below), which was a boat with four automatic musicians (a harpist, a flautist and two drummers), that floated on a lake to entertain guests at royal drinking parties. The mechanism featured a programmable drum machine with pegs (cams), that bump into little levers that operated the percussion. The drummer could be made to play different rhythms and different drum patterns if the pegs were moved around. The automata were a robot band, which performed more than fifty facial and body actions during each musical selection.

What Impact Did Al-Jazari’s Inventions Have on Future Generations?

Today, it’s widely recognized that some of Renaissance Europe’s greatest minds, including scientists, were inspired by the works of Muslims who preceded them, such as Ismail al-Jazari. Al Jazari, who was the chief engineer at the court of the Artuqids in Diyarbakir, recorded 100 of his ingenious inventions in his Book of Knowledge. When the book became available to wealthy patrons in 1206, they commissioned works based on his inventions. With the exception of five ornate chests with four-dial combination locks, few of these commissioned works are known to have survived.

Leonard da Vinci was said to have been influenced by a number of great Muslim thinkers and inventors, including Ibn Sina, Al Kindi, and Al-Jazari.
