Ibn Khalaf al-Murādī, (أبو جعفر علي ابن خلف المرادي; 11th century) was an Andalusian engineer.
Al-Murādī was the author of the technological manuscript entitled Kitāb al-asrār fī natā'ij al-afkār (Arabic: كتاب الأسرار في نتائج الأفكار, The Book of Secrets in the Results of Thoughts or The Book of Secrets in the Results of Ideas).[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.[citation needed]
In 2008, the Book of Secrets of al-Muradi was published in facsimile, translated in English/Italian/French/Arabic and in an electronic edition with all machines interpreted in 3D, by the Italian study center Leonardo3.
