Geber or Jabir (721?-815?)

Geber or Jabir (721?-815?), Arabian alchemist. Born Abu Musa Jabir ibn Hayyan, he is supposed to have lived in Al Kfah and Baghdd (both now in Iraq), and more than 500 treatises have been ascribed to him. Contemporary scholars, however, believe that most of these works date from the 9th to the 12th century. In addition, several works printed in Latin and ascribed to Geber, which is the Latin transcription of his Arabic name, probably date from the 14th century. These works give detailed descriptions of chemical processes, including experiments on the properties of metals. They develop the theoryof great importance to medieval and Renaissance scholarsthat all metals are composed of mercury and sulfur and that it is possible to transmute base metals into gold.
