Wābkanawīʼs prediction and calculations of the annular solar eclipse of 30 January 1283

The paper presents a critical review of the iterative process used by Shams al-Dīn Muḥammad al-Wābkanawī (Iran, Maragha, ca. 1270–1320) in order to compute the annular solar eclipse of 30 January 1283 from the solar and lunar parameter values obtained by Muḥyī al-Dīn al-Maghribī (Maragha, 1260–1274). The position of this prediction in medieval astronomy will also be discussed. Wābkanawī uses an observation as evidence for the correctness of his prediction, and his results agree to a remarkable extent with modern astronomical computations of the same eclipse.
