Abstract

The codex Cromwellianus 12 , one of the most interesting astrological manuscripts of the Bodleian Library in Oxford, contains on p. 450 f., under the heading 'Ιμβρασίου 'Εεσίου περί ρρώστων, the first part of the first part of Ps.-Galen's περι κατακλίσεως νοσούντων, which is, together with a work of Hermes Trismegistos, our principal source for iatromathematics, that is, for diagnosis and prognosis based on certain constellations, above all on the Moon's position in a particular sign of the zodiac. It is not the text itself that calls for notice—since we possess older and better manuscripts of it—but the mention of the author, Imbrasios of Ephesus, which only occurs here
