He was eventually caught by the Ummayads and executed. His family fled back to Yemen,E. J. Holmyard (ed.) "The Arabic Works of Jabir ibn Hayyan", translated byRichard Russell in 1678. New York, E. P. Dutton (1928); Also Paris, P. Geuther.] where Jabir grew up and studied the Koran, mathematics and other subjects under a scholar namedHarbi al-Himyari . After the Abbasids took power, Jabir went back to Kufa, where he spent most of his career.Jabir's father's profession may have contributed greatly to his interest in
alchemy . In Kufa he became a student of the celebrated Islamic teacher and sixthImam Ja'far al-Sadiq . He began his career practising medicine, under the patronage of the BarmakidVizir of CaliphHaroun al-Rashid . It is known that in 776 he was engaged in alchemy in Kufa.His connections to the Barmakid cost him dearly in the end. When that family fell from grace in 803, Jabir was placed under house arrest in Kufa, where he remained until his death. The date of his death is given as c.815 by the "
Encyclopædia Britannica ", but as 808 by other sources.Contributions
Chemistry
Jabir is mostly renowned for his contributions to
chemistry . He emphasised systematicexperiment ation, and did much to free alchemy fromsuperstition and turn it into ascience . He is credited with the invention of over twenty types of now-basic chemicallaboratory equipment, such as thealembic Will Durant (1980).

al-Kindi ,al-Razi ,al-Tughrai andal-Iraqi , who lived in the 9th-13th centuries. His books strongly influenced the medieval European alchemists and justified their search for thephilosopher's stone .

chemical substance s and instruments that are still used today.

steel and other metals, preventingrust , engravinggold , dyeing and waterproofing cloth, tanning leather, and the chemical analysis of pigments and other substances. He developed the use ofmanganese dioxide in glassmaking, to counteract the green tinge produced byiron — a process that is still used today. He noted that boilingwine released a flammable vapor, thus paving the way for the discovery ofethanol (alcohol ) byAl-Kindi andAl-Razi .cite web |url=http://www.history-science-technology.com/Notes/Notes%207.htm |title=Alcohol and the Distillation of Wine in Arabic Sources |accessdate=2008-03-29 |last=Hassan |first=Ahmad Y |authorlink=Ahmad Y Hassan |work=History of Science and Technology in Islam] According toIsmail al-Faruqi andLois Lamya al-Faruqi , "In response to Jafar al-Sadik's wishes, [Jabir ibn Hayyan] invented a kind ofpaper that resisted fire, and anink that could be read at night. He invented an additive which, when applied to aniron surface, inhabitedrust and when applied to atextile , would make it water repellent." [Ismail al-Faruqi andLois Lamya al-Faruqi (1986), "The Cultural Atlas of Islam", p. 328, New York]The seeds of the modern classification of elements into
metals and non-metals could be seen in his chemical nomenclature. He proposed three categories: [Georges C. Anawati, "Arabic alchemy", in R. Rashed (1996), "The Encyclopaedia of the History of Arabic Science", Vol. 3, p. 853-902 [866] .]*"Spirits" which vaporise on heating, like
arsenic (realgar ,orpiment ),camphor , mercury,sulfur ,sal ammoniac , andammonium chloride .
*"Metals", likegold ,silver ,lead ,tin ,copper ,iron , and "khar-sini";
*Non-malleable substances, that can be converted into powders, such as stones.The origins of the idea of chemical equivalents can also be traced back to Jabir, who was the first to recognize that "a certain quantity of acid is necessary in order to neutralize a given amount of base." According to Jabir, the
metal s differ because of "different proportions of sulfur and mercury in them." [citation|title=Equivalent Weights from Bergman's Data on Phlogiston Content of Metals|first1=J. A.|last1=Schufle|first2=George|last2=Thomas|journal=Isis|volume=62|issue=4|date=Winter 1971|pages=499-506 [500] ]In the
Middle Ages , Jabir's treatises on alchemy were translated into Latin and became standard texts forEurope an alchemists. These include the "Kitab al-Kimya" (titled "Book of the Composition of Alchemy" in Europe), translated byRobert of Chester (1144); and the "Kitab al-Sab'een" byGerard of Cremona (before 1187).Marcelin Berthelot translated some of his books under the fanciful titles "Book of the Kingdom", "Book of the Balances", and "Book of Eastern Mercury". Several technical Arabic terms introduced by Jabir, such as "alkali ", have found their way into various European languages and have become part of scientific vocabulary.Alchemy
Jabir became an alchemist at the court of
Caliph Harun al-Rashid , for whom he wrote the "Kitab al-Zuhra" ("The Book of Venus", on "the noble art of alchemy").Jabir states in his "
Book of Stones " (4:12) that "The purpose is to baffle and lead into error everyone except those whom God loves and provides for". His works seem to have been deliberately written in highly esoteric code (seesteganography ), so that only those who had been initiated into his alchemical school could understand them. It is therefore difficult at best for the modern reader to discern which aspects of Jabir's work are to be read as symbols (and what those symbols mean), and what is to be taken literally. Because his works rarely made overt sense, the termgibberish is believed to have originally referred to his writings (Hauck, p. 19).Jabir's alchemical investigations ostensibly revolved around the ultimate goal of "
takwin " — the artificial creation of life. The "Book of Stones" includes several recipes for creating creatures such asscorpion s,snake s, and evenhuman s in a laboratory environment, which are subject to the control of their creator. What Jabir meant by these recipes is today unknown.Jabir's interest in alchemy was probably inspired by his teacher
Ja'far al-Sadiq . Rumours of him being a Sufi is mostly fabricated for the main reason that no such school (i.e., Sufism) existed during that era of Islamic history. Ibn Hayyan was deeply religious, and repeatedly emphasizes in his works that alchemy is possible only by subjugating oneself completely to the will ofAllah and becoming a literal instrument of Allah onEarth , since the manipulation of reality is possible only for Allah. The "Book of Stones" prescribes long and elaborate sequences of specific prayers that must be performed without error alone in the desert before one can even consider alchemical experimentation.In his writings, Jabir pays tribute to Egyptian and Greek alchemists
Hermes Trismegistus ,Agathodaimon ,Pythagoras , andSocrates . He emphasises the long history of alchemy, "whose origin is Arius ... the first man who applied the "first" experiment on the [philosopher's] stone... and he declares that man possesses the ability to imitate the workings of Nature" (Nasr, Seyyed Hussein, "Science and Civilization of Islam").Jabir's alchemical investigations were theoretically grounded in an elaborate
numerology related to Pythagorean and Neoplatonic systems. The nature and properties of elements was defined through numeric values assigned the Arabic consonants present in their name, ultimately culminating in thenumber 17 .To
Aristotelian physics , Jabir added the four properties of hotness, coldness, dryness, and moistness (Burkhardt, p. 29). Each Aristotelian element was characterised by these qualities: Fire was both hot and dry, earth cold and dry, water cold and moist, and air hot and moist. This came from the elementary qualities which are theoretical in nature plus substance. In metals two of these qualities were interior and two were exterior. For example, lead was cold and dry and gold was hot and moist. Thus, Jabir theorised, by rearranging the qualities of one metal, based on their sulfur/mercury content, a different metal would result. (Burckhardt, p. 29) This theory appears to have originated the search for "al-iksir", the elusiveelixir that would make this transformation possible — which in European alchemy became known as thephilosopher's stone .The elemental system used in medieval
alchemy was developed by Jabir. His original system consisted of seven elements, which included the fiveclassical element s found in the ancient Greek and Indian traditions (aether , air, earth, fire and water), in addition to twochemical element s representing themetal s: sulphur, ‘the stone which burns’, which characterized the principle of combustibility, and mercury, which contained the idealized principle of metallic properties. Shortly thereafter, this evolved into eight elements, with the Arabic concept of the three metallic principles: sulphur giving flammability or combustion, mercury giving volatility and stability, and salt giving solidity.Strathern, Paul. (2000), "Mendeleyev’s Dream – the Quest for the Elements", New York: Berkley Books]Jabir also made important contributions to
medicine , astronomy/astrology, and other sciences. Only a few of his books have been edited and published, and fewer still are available in translation. The Geber crater, located on theMoon , is named after him.Legacy
Max Meyerhoff states the following on Jabir ibn Hayyan: "His influence may be traced throughout the whole historic course of European alchemy and chemistry."Ḥusain, Muẓaffar. "Islam's Contribution to Science." Page 94.]The historian of chemistry Erick John Holmyard gives credit to Jabir for developing alchemy into an experimental science and he writes that Jabir's importance to the
history of chemistry is equal to that ofRobert Boyle andAntoine Lavoisier .
