Jaghmini
Mahmūd ibn Muḥammad ibn Umar al-Jaghmini (Arabic: محمود بن محمد بن عمر الجغميني) or 'al-Chaghmīnī', or al-Jaghmini, was a 13th or 14th-century Arab[1][2] physician, astronomer and author of the Qanunshah (The Canon of Medicine) a short epitome of by Avicenna in Persian, and Mulakhkhas (Summary), a work on astronomy.
Several versified versions were also produced and considerable evidence exists of its use in medical teaching in the eastern provinces of the Islamic world.
The al-Mulakhkhas fi al-Hay'ah ("Epitome of plain theoretical astronomy") is an astronomical textbook describing the celestial orbs, the Earth, and their relations.
It is simplified compared to other astronomical texts from the same period, in that it lacks proofs and does not discuss the distances or sizes of celestial objects.
[3] The celebrated Ottoman-Turkish historian Haji Khalifa, in his biographic account contained in Sullam al-Wusūl, mentions reading al-Jaghmini's Mulakhas, together with another astronomical work, Ashkal al-ta'sis[n 1] by Shams al-Din Muhammad ibn Ashraf al-Samarqandi, with his tutor A'rej Mehmed Efendi, between the years 1643-45 AD..[4] For a discussion of his popular epitome, the Qanuncheh, and the use made of it by subsequent generations of medical students, see:
