 Arabic sources, such as Muhammad ibn Zakarīya al-Rāzi (AD 865–925), continue to be the source of discovery of new or relatively inaccessible Galenic writings.One of Hunayn's Arabic translations, "Kitab ila Aglooqan fi Shifa al Amrad", which is extant in the Library of Ibn Sina Academy of Medieval Medicine & Sciences, is regarded as a masterpiece of Galen's literary works.A part of the Alexandrian compendium of Galen's work, this 10th-century manuscript comprises two parts that include details regarding various types of fevers (Humyat) and different inflammatory conditions of the body.
