The Arabic original of (ps.) Māshā'allāh's Liber de orbe: its date and authorship
British Journal for the History of Science
AbstractLiber de orbe, attributed to Māshā'allāh (d.c.815), a court astrologer of the Abbasid dynasty, was one of the earliest Latin sources of Aristotelian physics. Until recently, its Arabic original could not be identified among Arabic works. Through extensive examination of Arabic manuscripts on exact sciences, I found two manuscripts containing the Arabic text of this Latin work, although neither of them is ascribed to Māshā'allāh: Berlin, Staatsbibliothek zu Berlin, Ms. or. oct. 273, anddoi:10.1017/s0007087414000910 pmid:25921684 fatcat:ixx5xpc7wvhilizkn34ahy5ghu
