Mahmud ibn Muhammad ibn Umar Jaghmini
Jaghmīnī is the author of the ubiquitous elementary astronomical text al‐Mulakhkhaṣ fī al‐hayʾa al‐basīṭa (Epitome of plain theoretical astronomy). This popular, simplified (i.e., without proofs) introduction to astronomy, written in Arabic, was the subject of an enormous number of extant commentaries and supercommentaries. These commentaries (many written in Persian as well as Arabic) were meant to be studied along with the Mulakhkhaṣ and used as supplements for more advanced teaching texts.
