ISLAMIC Alchemy

Aidamir al-Jildaki (?-1342)

Who also lived for part of his life at Cairo, is of importance chiefly on account of his extensive and deep knowledge of Muslim chemical literature. He apparently spent the major portion of his existence in collecting and explaining all the books upon alchemy that he could discover, and labours are now beginning to receive their reward; for writings form an indispensable source of a great deal of our knowledge of chemistry and chemists in Islam. In a few instances it is possible to observe that he must have carried out experimental work himself, but for the most part his books are commentaries upon the works of earlier writers. Thus his great End of the Search is a commentary upon Abu'l-Qasim's book Knowledge acquired concerning the Cultivation of Gold, and although his explanations are not seldom more obscure than the passages they are designed to illuminate, he had the admirable habit of making innumerable and lengthy quotations from Khalid, Jabir, Razi and many other authors, and his books are thus a rich storehouse of information upon Muslim chemistry. It is therefore necessary to inquire into the question whether his quotations and historical facts are authentic, and whether his reliability is to be accepted or doubted. Fortunately, it often happens that a book from which he quotes is extant, and his quotations in such cases can of course be checked. A test conducted on these lines has shown that Jildaki was conscientious and although he does not always come through unscathed, his general trustworthiness can be safely assumed. He thus deserves the warmest thanks of all who are interested in the history of chemistry.
