state with some advantage; but in a science still more difficult, he failed completely. He could not rule his own passions, but gave himself up to wine and women, and led a life of shameless debauchery. Amid the multifarious pursuits of business and pleasure, he nevertheless found time to write seven treatises upon the philosopher's stone, which were for many ages looked upon as of great value by pretenders to the art. It is rare that an eminent physician as Avicenna appears to have been, abandons himself to sensual gratification; but so completely did he become enthralled in the course of a few years, that he was dismissed from his high office, and died shortly afterwards of premature old age and a complication of maladies, brought on by debauchery. His death took place in the year 1036. After his time few philosophers of any note in Arabia are heard of as devoting themselves to the study of alchymy; but it began shortly afterwards to attract greater attention in Europe. Learned men in France, England, Spain, and Italy, expressed their belief in the science, and many devoted their whole energies to it. In the twelfth and thirteenth centuries especially, it was extensively pursued, and some of the brightest names of that age are connected with it. Among the most eminent of them are
Albertus Magnus and Thomas Aquinas.
The first of these philosophers was born in the year 1193, of a noble family at Lawingen, in the Duchy of Neuburg, on the Danube. For the first thirty years of his life he appeared remarkably dull and stupid, and it was feared by every one that no good could come of him. He entered a Dominican monastery at an early age; but made so little progress in his studies, that he was more than once upon the point of abandoning them in despair, but he was endowed with extraordinary perseverance. As he advanced to middle age, his mind expanded, and he learned whatever he applied himself to with extreme facility. So remarkable a change was not in that age to be accounted for but by a miracle. It was asserted and believed that the Holy Virgin, touched with his great desire to become learned and famous, took pity upon his incapacity, and appeared to him in the cloister where he sat almost despairing, and asked him whether he wished to excel in philosophy or divinity. He chose philosophy, to the chagrin of the Virgin, who reproached him in mild and sorrowful accents that he had not made a better choice. She, however, granted his request, that he should become the most excellent philosopher of the age; but set this drawback to his pleasure, that he should relapse, when at the height of his fame, into his former incapacity and stupidity. Albertus never took the trouble to contradict the story,
