This is a rare book and can hardly be found outside libraries. It was translated by late Dr. Donald Hill from Arabic in 1974. The book was written in 1205 one year before Al Jazari's death in Diyarbakir. He tells us in the entry part of the manuscript that his sponsor is the local ruler of Diarbekr, Mohammed bin Kara Arslan bin Artuk and that he has worked for him a total of 25 years.
There are about 40 mechanical devices and engines described with illustrations. One of the machines show a very clearly depicted and illustrated camshaft more than two centuries before Leonardo Da Vinci. This book also shows suction pipes, pumps, double-action pump, a twin-cylinder reciprocating piston suction pump as well as many other human figured automata that works with hydraulic power, such as music instrument playing human size robots.
This historical book's earliest manuscript is kept in the Topkapi Palace. A coloured facsimile copy has been published in 1998 by the Turkish Ministry of Culture and a Turkish translation has been published in 2006. However, a 3D illustrated modern book for the layman is still not available to show the importance of his inventions.
One really wonders if there was an earlier precedent of Jazari, further East where his sponsors migrated from, since these 40 robots and machines are too advanced (for its time) and so well developed to be the fruit of one human life.
