الشكوك على بطلميوس
al-Shukūk ʿalā Baṭlamyūs
An extensive collection of various types of criticisms of three works of Ptolemy, namely the Almagest (specifically Books I, V, VI, IX, X, and XIII), the Planetary Hypotheses, and the Optics. Ibn al-Haytham criticizes, among other things, Ptolemy’s methods of calculation, his models of planetary motion, and contradictions within one work or between two works. He works with frequent literal citations and juxtaposes statements from the Almagest with statements from the Planetary Hypotheses or the Optics. The text has no explicit subdivisions, but is textually divided into three parts dealing respectively with the three works. According to Rashed (‘The Celestial Kinematics’), al-Shukūk was written between 1028 and 1038 CE. The two extant manuscripts are incomplete, but complement each other so that together they transmit the entire treatise.
Origin: If Rashed’s thesis is correct, namely that the works that are ascribed to Ibn al-Haytham have to be distributed between works written by the philosopher Muḥammad Ibn al-Haytham and the mathematician al-Ḥasan Ibn al-Haytham, this treatise belongs to the latter (Rashed, ‘The Configuration’; in contrast, see Sabra, ‘One Ibn al-Haytham’ and ‘One Ibn al-Haytham. Conclusion’).
