Albertus Magnus
 
From Jovius’ Vitae Illustrium Virorum.

Albert de Groot was born about 1206 and died at the age of 74. It has been said of him that he was "magnus in magia, major in philosophia, maximus in theologia." He was a member of the Dominican order and the mentor of St. Thomas Aquinas in alchemy and philosophy. Among other positions of dignity occupied by Albertus Magnus was that of Bishop of Regensburg.
He was beatified in 1622. Albertus was an Aristotelian philosopher, an astrologer, and a profound student of medicine and physics. During his youth, he was considered of deficient mentality, but his sincere service and devotion were rewarded by a vision in which the Virgin Mary appeared to him and bestowed upon him great philosophical and intellectual powers. Having become master of the magical sciences, Albertus began the construction of a curious automaton, which he invested with the powers of speech and thought. The Android, as it was called, was composed of metals and unknown substances chosen according to the stars and endowed with spiritual qualities by magical formulae and invocations, and the labor upon it consumed over thirty years. St. Thomas Aquinas, thinking the device to be a diabolical mechanism, destroyed it, thus frustrating the labor of a lifetime. In spite of this act, Albertus Magnus left to St. Thomas Aquinas his alchemical formulae, including (according to legend)the secret of the Philosopher’s Stone.

On one occasion Albertus Magnus invited William II, Count of Holland and King of the Romans, to a garden party in midwinter. The ground was covered with snow, but Albertus had prepared a sumptuous banquet in the open grounds of his monastery at Cologne. The guests were amazed at the imprudence of the philosopher, but as they sat down to eat Albertus uttered a few words, the snow disappeared, the garden was filled with flowers and singing birds, and the air was warm with the breezes of summer. As soon as the feast was over, the snow returned, much to the amazement of the assembled nobles. (For details, see The Lives of Alchemystical Philosophers.) MPH
