Ismail al-Jazari (1136 - 1206) an Arab Muslim polymath: a scholar, inventor, mechanical engineer, artisan, artist and mathematician. It is worth mentioning that he invented the first operational robot in history which was powred by water flow. This one illustrated here is a hand-washing and ablution automaton with a flush mechanism.
Also he invented the crankshaft and crank-slider mechanism , a concept which all operating cars, planes, trains and heacy machinary works tody.
I've done this art work in 2013 for my friend Abdulrahman Alnahar who owned a facebook page which talks about Islamic science scholars and I was happy that this illustration was used in Syrian Istanbul Exhibition 2014 , as well Syrian refuges schools in Turky.
If anyone wishs to use it for schools, charity , philanthropy projects, then please dont hesitate to contact me.
