See Abu Jafar al-Muradi for the Egyptian grammarian.

Alī Ibn Khalaf al-Murādī, (11th century) Al-Andalus, was a Mechanical engineer and author of the unique technological manuscript entitled Kitāb al-asrār fī natā'ij al-afkār (The Book of Secrets in the Results of Thoughts).[1] It was copied and used at the court of Alfonso VI of León and Castile in Christian Spain in the 11th century.[citation needed]

The manuscript provides information about a "Castle and Gazelle Clock" and many other forms of complicated clocks and ingenious devices. Al-Muradi was a contemporary of Abū Ishāq Ibrāhīm al-Zarqālī.[citation needed]

In 2008, the Book of Secrets of al-Muradi has been published in facsimile, translated in English/Italian/French/Arabic and in electronic edition with all machines interpreted in 3D, by the Italian study center Leonardo3.

He also devised, with help from al-Zarqali, the universal astrolabe.[2] Both al-Muradi and al-Zarqali's design were included in the Libros del Saber (1227) of Alfonso X of Castile.[3]
