Al Soft, or “The Wise,” and he was born at Hauran, in Mesopotamia.¹ Some have thought he was a Greek, others a Spaniard, and others, a prince of Hindostan: but, of all the mistakes which have been made respecting him, the most ludicrous was that made by the French translator of Sprenger’s History of Medicine, who thought, from the sound of his name, that he was a German, and rendered it as the “Donnateur,” or Giver. No details of his life are known; but it is asserted, that he wrote more than five hundred works upon the philosopher’s stone and the water of life. He was a great enthusiast in his art, and compared the incredulous to little children shut up in a narrow room, without windows or aperture, who, because they saw nothing beyond, denied the existence of the great globe itself. He thought that a preparation of gold would cure all maladies, not only in man, but in the inferior animals and plants. He also imagined that all the metals laboured under disease, with the exception of gold, which was the only one in perfect health. He affirmed, that the secret of the philosopher’s stone had been more than once discovered; but that the ancient and wise men who had hit upon it, would never, by word or writing, communicate it to men, because of their unworthiness and incredulity.² But the life of Geber, though spent in the pursuit of this vain chimera, was not altogether useless. He stumbled upon discoveries which he did not seek, and science is indebted to him for the first mention of corrosive sublimate, the red oxide of mercury, nitric acid, and the nitrate of silver.³

For more than two hundred years after the death of Geber, the Arabian philosophers devoted themselves to the study of alchymy, joining with it that of astrology. Of these the most celebrated was

ALfarabi

    Alfarabi flourished at the commencement of the tenth century, and enjoyed the reputation of being one of the most learned men of his age. He spent his life in travelling from country to country, that he might gather the opinions of philosophers upon the great secrets of nature. No danger dismayed him; no toil wearied him of the pursuit. Many sovereigns endeavoured to retain him at their courts; but he refused to rest until he had discovered the great object of his life — the art of preserving it for centuries, and of making gold as much as he needed. This wandering mode of life at last proved fatal to him. He had been on a visit to Mecca, not so much for religious as for philosophical purposes, when, returning through Syria, he stopped at the court of the Sultan Seifeddoulet, who was renowned as the patron of learning. He presented himself in his travelling attire, in the presence of that monarch and his courtiers; and, without invitation, coolly sat himself down upon the sofa, beside the Prince. The courtiers and wise men were indignant; and the Sultan, who did not know the intruder, was at first inclined to follow their example. He turned to one of his officers, and ordered him to eject the presumptuous stranger from the room; but Alfarabi, without moving, dared them to lay hands upon him; and, turning himself calmly to the prince, remarked, that he did not know who was his guest, or he would treat him with honour, not with violence. The Sultan, instead of being still further incensed, as many potentates would have been, admired his coolness; and, requesting him to sit still closer to him on the sofa, entered into a long conversation with him upon science and divine philosophy. All the court were charmed with the stranger. Questions for discussion were propounded, on all of which he showed superior knowledge. He convinced every one that ventured to dispute with him; and spoke so eloquently upon the science of alchymy, that he was at once recognised as only second to the great Geber himself. One of the doctors present inquired whether a man who knew so many sciences was acquainted with music? A1farabi made no reply, but merely requested that a lute should be brought him. The lute was brought; and he played such ravishing and tender melodies, that all the court were melted into tears. He then changed his theme, and played airs so sprightly, that he set the grave philosophers, Sultan and all, dancing as fast as their legs could carry them. He then sobered them again by a mournful strain, and made them sob and sigh as if broken- hearted. The Sultan, highly delighted with his powers, entreated him to stay, offering him every inducement that wealth, power, and dignity could supply; but the alchymist resolutely refused, it being decreed, he said, that he should never repose till he had discovered the philosopher’s stone. He set out accordingly the same evening, and was murdered by some thieves in the deserts of Syria. His biographers give no further particulars of his life beyond mentioning, that he wrote several valuable treatises on his art, all of which, however, have been lost. His death happened in the year 954.
