Shatir
Alaa al-Din Ali ibn-Ibrahim Ibn-al-Shatir born and died in Damascus (Syria), (1305-1375), was the most distinguished Muslim astronomer of the 14th century. His most significant contribution to astronomy was his planetary theory. In his planetary models, Ibn-al-Shaṭir incorporated various ingenious modifications of those of Ptolemy. Also, with the reservation that they are geocentric, his models are the same as a number used by Copernicus. Ibn-al-Shatir’s planetary theory was investigated for the first time in the 1950s, and the discovery that his models were mathematically identical to those of Copernicus raised the very interesting question of a possible transmission of his planetary theory to Europe. In "Nihayat al‐sul fi taṣḥiḥ al‐uṣul" (A final inquiry concerning the rectification of planetary theory), Ibn-al-Shaṭir presented the reasoning behind his new planetary models. The essence of Ibn-al-Shaṭir's planetary theory is the apparent removal of the eccentric deferent and equant of the Ptolemaic models, with secondary epicycles used instead. Finally, Ibn-al-Shaṭir's "al‐Zij al‐jadid" (The new astronomical handbook), extant in several manuscript copies, contains a new set of planetary tables based on his new theory and parameters. Several works by the scholars of the mid‐13th century observatory at Maragha are mentioned in Ibn-a-Shatir’s introduction to this treatise, and it is clear that these were the main sources of inspiration for his own Non‐Ptolemaic planetary models. Ibn-al-Shatir designed and constructed a magnificent horizontal sundial that was erected on the northern minaret of the Umayyad Mosque in Damascus.
