بيت الحكمة
The Translation Movement started in this House of Wisdom and lasted for over two centuries. Over a century and a half, primarily Middle Eastern Oriental Syriac Christian scholars translated all scientific and philosophic Greek texts into Arabic language in the House of Wisdom. The translation movement at the House of Wisdom was inaugurated with the translation of Aristotle's "Topics". By the time of Al-Ma'mun, translators had moved beyond Greek astrological texts, and Greek works were already in their third translations. Authors translated include: Pythagoras, Plato, Aristotle, Hippocrates, Euclid, Plotinus, Galen, Sushruta, Charaka, Aryabhata and Brahmagupta. Many important texts were translated during this movement including a book about the composition of medicinal drugs, a book on this mixing and the properties of simple drugs, and a book on medical matters by Pedanius Dioscorides. These, and many more translations, helped with the advancements in medicine, agriculture, finance, and engineering.
