Baghdad's House of Wisdom was real, but its university image may be modern
Popular history pictures the House of Wisdom as a medieval university with departments and formal debates. Some historians now argue that image took shape in the 19th and early 20th centuries through mistranslation and hindsight. What survives is still remarkable: a caliph's library where scholars rendered Greek science into Arabic.
Its origins are uncertain. It may have started out holding Harun al-Rashid's books, late in the 700s, or as al-Mansur's personal store of rare Arabic volumes; al-Mansur is the caliph who built Baghdad in 762 and moved the capital there from Damascus. Al-Mansur modelled a palace library on the Sasanian imperial one and invited Indian scholars to share mathematics and astronomy. An early name, Khizanat al-Hikma, means storehouse of wisdom, reflecting its role in preserving rare books and poetry. The key medieval reference is Ibn al-Nadim's catalogue al-Fihrist; he died in 995.
It was one part of a wider movement. Translation work had flourished earlier in Cairo and Damascus, where the Umayyad caliph Muawiyah I had assembled books. Under the Abbasids, texts arrived from Greek, Syriac, Persian, Sanskrit and Chinese, starting with medicine, mathematics and astronomy before philosophy followed. Hunayn ibn Ishaq, a Christian physician who lived from 809 to 873, led the translators and produced 116 works, including the Greek medical corpus of Galen and Hippocrates. Thabit ibn Qurra rendered Euclid, Archimedes, Apollonius and Ptolemy.
Al-Ma'mun, caliph from 813 to 833, turned it into a public academy and library and funded it lavishly. Reportedly inspired by a dream about Aristotle, he hosted and refereed debates, built Baghdad's first observatories, and organised teams to map the world, check Ptolemy's data and estimate the Earth's size, an early form of state-funded big science. He is said to have demanded a copy of the Almagest as a condition of peace with the Byzantines. Its scholars also worked as engineers, calendar-keepers and physicians.
Support continued under al-Mu'tasim and al-Wathiq, who shared al-Ma'mun's rationalist Mu'tazili outlook, but declined sharply under al-Mutawakkil, who reigned from 847 to 861 and regarded Greek philosophy as a threat to Islam. The library was destroyed during the Mongol siege of Baghdad in 1258.
