Alī Ibn Khalaf al-Murādī, (Arabic: أبو جعفر المرادي; 11th century) was an
Andalusian mathematician and astronomer who belonged to the scientific
circle of Ṣāʿid al- Andalusī.
He was the author of
the technological manuscript entitled Kitāb al-asrār fī natā'ij
al-afkār (The Book of Secrets in the Results of Thoughts or The
Book of Secrets in the Results of Ideas). It was copied and used at
the court of Alfonso VI of León and Castile in Christian Spain in the
11th century.
Fragment of The Book of Secrets in the Results of Thoughts. 11th century
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.
In 2008, the Book of
Secrets of al-Muradi has been 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.
He also devised, with
help from al-Zarqali, the universal astrolabe. Both al-Muradi and al-Zarqali's
design were included in the Libros del Saber (1227)
of Alfonso X of Castile.
