Athīr Al-Dīn Al-Abharī
Athīr al-Dīn al-Mufaḍḍal ibn ʿUmar ibn al-Mufaḍḍal al-Samarqandī al-Abharī (Persian): اثیرالدین مُفَضَّل بن عمر بن مَفَضَّل سمرقندی ابهری; d. 1262 or 1265 also known as Athīr al-Dīn al-Munajjim (اثیرالدین منجم) was an Iranian Muslim polymath, philosopher, astronomer, astrologer and mathematician. Other than his influential writings, he had many disciples. Life His birthplace is contested among sources. According to the ''Encyclopaedia of Islam'' and the ''Encyclopaedia Islamica'', he was born in Abhar, a small town between Qazvin and Zanjan in the North-West of Iran. The claim of G.C. Anawati making him a native of Mosul in Iraq, taken from the fact that al-Abharī was educated by a scientist from Mosul, Kamāl al-Dīn ibn Yūnus al-Mawṣilī, must also been dismissed. None of his oldest biographers mentioned Mosul as his birthplace, and al-Abharī himself indicated that he had gone to Mosul for this purp ...
