Segmental gears ("a piece for receiving or communicating reciprocating motion from or to a cogwheel, consisting of a sector of a circular gear, or ring, having cogs on the periphery, or face." and epicyclic gears were both first invented by the 11th century Arab engineer Ibn Khalaf al-Muradi from Islamic Spain. He employed both these types of gears in the gear trains of his mechanical clocks. Simple gears have been known before him, but this was the the first known case of complex gears used to transmit high torque.

It is a priceless manuscript, as it includes descriptions and drawings of more than thirty ingenious devices including mechanical apparatuses, water clocks, automatic calendars and war machines. It was copied in 1266 (in Toledo) from an original dating back to the eleventh century by the Andalusian engineer Ibn Khalaf al-Muradi. It is an extraordinarily important manuscript in the field of the history of science, because it represents one of the earliest written and drawn testimonies about complex ancient machines and has never before been studied or divulged.

The auspices of the Emir of Qatar, His Highness Sheikh Hamad bin Khalifa Al-Thani, has allowed the funding of an entire research group that, after months of work, has given exceptional results. The complexity of the manuscript had prevented many experts from interpreting it. Thanks to the competence and the technology of the Italian research center Leonardo3, th ...more
