  1. Solar and lunar observations at Istanbul in the 1570s.John M. Steele & S. Mohammad Mozaffari - 2015 - Archive for History of Exact Sciences 69 (4):343-362.
    From the early ninth century until about eight centuries later, the Middle East witnessed a series of both simple and systematic astronomical observations for the purpose of testing contemporary astronomical tables and deriving the fundamental solar, lunar, and planetary parameters. Of them, the extensive observations of lunar eclipses available before 1000 AD for testing the ephemeredes computed from the astronomical tables are in a relatively sharp contrast to the twelve lunar observations that are pertained to the four extant accounts of (...)

  • Planetary latitudes in medieval Islamic astronomy: an analysis of the non-Ptolemaic latitude parameter values in the Maragha and Samarqand astronomical traditions.S. Mohammad Mozaffari - 2016 - Archive for History of Exact Sciences 70 (5):513-541.
    Some variants in the materials related to the planetary latitudes, including computational procedures, underlying parameters, numerical tables, and so on, may be addressed in the corpus of the astronomical tables preserved from the medieval Islamic period, which have already been classified comprehensively by Van Dalen. Of these, the new values obtained for the planetary inclinations and the longitude of their ascending nodes might have something to do with actual observations in the period in question, which are the main concern of (...)

  • In Synchrony with the Heavens : Studies in Astronomical Timekeeping and Instrumentation in Medieval Islamic Civilization.David King - 2005 - Brill.
    This is the first investigation of timekeeping by the sun and stars and the regulation of the astronomically-defined times of Muslim prayer. The study is based on over 500 medieval astronomical manuscripts first identified by the author. A second volume and third volume, also published by Brill, deals with astronomical instruments for timekeeping and other computing devices.

  • A forgotten solar model.S. Mohammad Mozaffari - 2016 - Archive for History of Exact Sciences 70 (3):267-291.
    This paper analyses a kinematic model for the solar motion by Quṭb al-Dīn al-Shīrāzī, a thirteenth-century Iranian astronomer at the Marāgha observatory in northwestern Iran. The purpose of this model is to account for the continuous decrease of the obliquity of the ecliptic and the solar eccentricity since the time of Ptolemy. Shīrāzī puts forward different versions of the model in his three major cosmographical works. In the final version, in his Tuḥfa, the mean ecliptic is defined by an eccentric (...)
