 Another group of translators takes the floor a bit later: the one of the Nestorian physician and scientist Hunayn ibn Ishaq (d. 873) (Bergsträsser 1913, 1925; Gabrieli 1924; Meyerhof 1926a, 1926b; Haddad 1974; Strohmaier 1990) his son Ishaq ibn Hunayn (d. 911), and their associates. In addition to the medical corpus of  Galen,[50]  this group of translators made available in Syriac and/or in Arabic other works by Plato, Aristotle, Theophrastus, some philosophical writings by Galen, as well as works by Alexander of Aphrodisias, Porphyry, perhaps Iamblichus, Themistius, Proclus, and John Philoponus.
