Alchemy

Alchemy The science by aid of which the chemical philosophers of medieval times attempted to transmute the baser metals into gold or silver. There is considerable divergence of opinion as to the etymology of the word, but it would seem to be derived from the Arabic al=the, and kimya=chemistry, which in turn derives from the late Greek chemica=chemistry, from chumeia=a mingling, or cheein, ‘to pour out‘ or ‘mix’, Aryan root ghu, to pour, whence the word ‘gush’. Mr. A. Wallis Budge in his "Egyptian Magic", however, states that it is possible that it may be derived from the Egyptian word khemeia, that is to say ‘the preparation of the black ore’, or ‘powder’, which was regarded as the active principle in the transmutation of metals. To this name the Arabs affixed the article ‘al’, thus giving al-khemeia, or alchemy. HISTORY OF ALCHEMY: From an early period the Egyptians possessed the reputation of being skillful workers in metals and, according to Greek writers, they were conversant with their transmutation, employing quicksilver in the process of separating gold and silver from the native matrix. The resulting oxide was supposed to possess marvelous powers, and it was thought that there resided within in the individualities of the various metals, that in it their various substances were metals, alchemy, alchemical, science, must, stone, process, nature, art, transmutation, matter, gold, century, ca, thus, throughout, through, theory, spain, silver, male, later, however, female, elements, egyptian, black, being, baser, alchemist, water, warm, various, upon, times
