Tag: Ibn al-Haytham



I have already mentioned in passing a number of Arab inventions from the Golden Age. They include a wide range of medical, chemical and astronomical devices. But there are whole other areas in which the Arabs inventors excelled.

         Arab engineers learned from the Romans, Greeks and from their own scientists, and came up with creations that demonstrated their astonishing ingenuity. Some of these creations improved living conditions, while others were more whimsical.

         Engineers were hugely important. When the tenth century Persian engineer and polymath, Ibn al-Haytham (Alhazen), reached Cairo, the Caliph himself went to the gates to greet him. He had been invited to regulate the flooding on the Nile. It soon dawned on him that he couldn’t solve the problem. The only way to save his neck was to feign madness and live for years under house arrest… biding his time until the Caliph’s own death.




Just like the Classical world before and the so called Renaissance Men after, the golden age of Islam was championed by polymaths, whose works rival those of Aristotle, Da Vinci or Newton.

The Arab polymaths arrived in the Renaissance under their Latinised names. For example,

1.    Ibn Sina was Avicenna

2.    Ibn Bajjah was Avempace

3.    Ibn Hayyan was Geber

4.    Ibn Rushd was Averroes

5.    Al-Kindi was Alkindus

6.    Ibn al-Haytham was Alhazen

They were so important because they used breakthroughs in one area to push forward knowledge and understanding in another. Indeed, ‘Polymathy’ is a method that has almost been lost in the West, and is only now being rediscovered – so called ‘interdisciplinary’ study. (e.g. Stanford University’s new Bio-X Program, which brings together biologists, computer scientists, medical scientists and engineers, who learn from each other’s fields). The scientists and Polymaths from the golden age worked on areas of science which are familiar to us all, and are still being studied in schools and universities today, with the same scientific method.
