This article describes the remarkable model for planetary latitude presented in the Ḫāqānī Zīj by Ġiyāṯ al-Dīn Jamšīd al-Kāšī (d. AD 1429), who is particularly well-known for his leading role in Ulugh Beg’s observatory at Samarkand and his exceptional computational skills. al-Kāšī designed a three-dimensional model for the planetary latitudes that allowed their calculation with much more precision than Ptolemy’s two-dimensional model with separate treatment of the three latitude components fo..
