Muḥammad ibn al-ʿAbbās Abū Bakr al-Khwārazmī, better simply known as Abu Bakr al-Khwarazmi was a 10th-century Iranian poet and secretary, who throughout his long career served in the court of the Hamdanids, Samanids, Saffarids and Buyids.[1] He is best known as the author of the early encyclopedia Mafātīḥ al-ʿulūm (“Key to the Sciences”) in the Arabic language.
Al-Khwarazmi is a somewhat obscure figure.[2] He was born in 935 in Khwarazm, the birthplace of his father. His mother was a native of Amol in Tabaristan.[1] He periodically refers to himself as al-Khwarazmi or al-Tabari, while other sources refer to him as al-Tabarkhazmi or al-Tabarkhazi.[1] Al-Khwarizmi may have been a nephew of al-Tabari, the prominent Persian historian.[1] For a time, al-Khwarizmi worked as a clerk in the Samanid court at Bukhara in Transoxania,[2][3] where he acquired his nickname, “al-Katib’’ which literally means “the secretary” or “the scribe”.[4]
While at the Samanid court, he compiled his best-known work, Mafātīḥ al-ʿulūm [The Keys of the Sciences], an early Islamic encyclopedia of the sciences, intended as a reference work for court officials. It was produced at the request of Abū l-Ḥasan al-ʿUtbī a vizier in the court of Amir, Nuh II.[5][6] and the work is dedicated to al-Utbi which establishes a date for its completion of around 977.[7][2] In Nishapur, Al-Khwarizmi wrote a number of rihla (short, humorous accounts of a journey; partly written in verse and partly in literary prose), of which only fragments survive.[8] Locally, he achieved great fame as a leading scholar and writer. However, his reputation was eclipsed following the arrival of an aspiring young scholar and writer, Badi' al-Zaman al-Hamadani in 383/992. Hamadani composed a new form of prose that gained enormous popularity firstly in Nishapur and later across the Arabic speaking world. This innovative genre that became known as maqama. Al-Khwārizmīand Hamadani fell into competition with each other, exchanged insults and they eventually fell out.[9]
Al-Khwārizmī authored a work on Arabic grammar, Kitāb kifāyat al-Mutaḥaffiẓ [A Classified Vocabulary of Rare of Difficult Arabic words]. However, he is best known as the author of Mafātīḥ al-ʿulūm (The Keys to the Sciences), an early Islamic Encyclopedia of the Sciences.[10] A monumental work, Mafātīḥ al-ʿulūm is part lexicography and part encyclopedia.[11] Scholars regard it as the first attempt to document the Islamic sciences.[12] The work includes sections on mathematics, alchemy, medicine and meteorology.[13]
Only limited selections of Mafātīḥ al-ʻulūm have been translated into English. Notable editions and translations include:
