	The Astronomical Clock of Taqi Al-Din: Virtual Reconstruction
	By: FSTC Limited, Thu 19 June, 2008
	In his book The Brightest Stars for the Construction of Mechanical Clocks (Al-Kawakib al-durriyya fi wadh' al-bankamat al-dawriyya), Taqi al-Din Ibn Ma'ruf analyses the four main types of time keeping devices known in the 16th century: watches, domestic clocks, astronomical clocks and tower clocks. Such machines represent the earliest mechanical computers. In the following, we present for the first time a virtual reconstruction of the astronomical clock type through geometrical drawing and 3D animation.

	By: Abdel Aziz al-Jaraki, Wed 11 April, 2007
	The following article by Abdel Aziz al-Jaraki, a scholar from Damascus, describes the context of the investigation carried on since several decades on a famous clock built by Fakhr al-Din Ridhwan al-Sa'ati at the beginning of the 6th centuty of Hijra (1202 CE) in his work `Amal al-Sa'at wa 'l-`Amal biha (The Operation of clocks and working with them).

	The Machines of Al-Jazari and Taqi Al-Din
	By: FSTC Limited, Thu 30 December, 2004
	Prof. Salim T S Al-Hassani In this pioneering survey of some of the machines of Al-Jazari and Taqi Al-Din, Professor Salim Al-Hassani uses in-depth analysis with the tools of modern technology to make them live again. Relying on the original manuscripts and applying modern engineering technology and graphic modelling with computers, we can see these machines designed and described many centuries ago come to life.
