The fields to which scholars associated with the House of Wisdom contributed include, but are not limited to philosophy, mathematics, medicine, astronomy, and optics.[6][5] The early name of the library, Khizanat al-Hikma (literally, “Storehouse of Wisdom”), derives from its function as a place for the preservation of rare books and poetry, a primary function of the House of Wisdom until its destruction.[1]
