How were they lost or rediscovered? "Muhammad ibn Zakariya al-Razi (Latinized: Rhazes) (born 865) was one of the most versatile scientists of the Islamic Golden Age ... Many of his books were translated into Latin, and he remained one of the undisputed authorities in European medicine well into the 17th century." "Ibn Sina, more commonly known in west as Avicenna was a Persian polymath and physician of the tenth and eleventh centuries. He was known for his scientific works, but especially his writing on medicine." "Ibn Buṭlān, ... was an Arab physician who was active in Baghdad during the Islamic Golden Age.[64] He is known as an author of the Taqwim al-Sihhah (The Maintenance of Health تقويم الصحة), in the West, best known under its Latinized translation, Tacuinum Sanitatis (sometimes Taccuinum Sanitatis)." More than this, a lot of the scholarship in the Islamic world preserved discoveries by the Greeks: "Galen is one of the most famous scholars and physicians of classical antiquity. Today, the original texts of some of his works, and details of his biography, are lost, and are only known to us because they were translated into Arabic" Or did the Greeks not 'actually' discover anything, either?
