Stephanos

The alchemists Zosimos and Stephanos, writing in Alexandria during the first Christian centuries, had described the chemical process in the form of a story of ritual sacrihce incorporating priest and initiates. In a well-known study, Mircea Eliade sought for the origins of such bloody accounts in ancient shamanism and metal-smithing. The materials of the stone, like the human body and soul, died and underwent purihcation, prior to their resurrection in a glorious body.

These events horrified the young Khalid, and he withdrew from court life to study the sciences. In Alexandria, Khalid furthered his studies of alchemy under a Christian scholar by the name of Morienus, who is supposed to be have been a pupil of Stephanos of Alexandria (fl. 610—641), perhaps the most eminent alchemist in Egypt since the time of Zosimos. 

Stephanos was a favourite at the court of the Byzantine Emperor Herakleios I, who, aside from being a great military leader, was also a man of learning and seems to have done much to encourage the intellectual life of the time. Like the later Holy Roman Emperor Rudolph II, Herakleios seems to have devoted so much time to the study of alchemy in his later years that affairs of state took second place to the search for the Stone.

Efforts in engineering science reinforce these observations (Stephano-poulos, 1987). Many tasks are not achievable if representational expressivity isn t sufficiently rich to allow the description of the necessary concepts (Brachman and Levesque, 1985). Concepts must be manipulated directly if powerful reasoning is to be achieved. The success of any advanced computer-aided tool for enhancing the identification of hazards requires (1) the development of a representational language sufficiently rich to embody advanced scientific concepts and (2) a means for manipulating these concepts and reasoning about them, directly.

From the seventh through the thirteenth centuries, the study of alchemy flourished openly in the Islamic world. The first Muslim with an interest in alchemy may have been Khalid Ibn Yazid (d. 704), a Umayyad prince. He reputedly was tutored in alchemy by a student of Stephanos, Morienus of Alexandria (who is quoted by the author of the Splendor Solis). Whether or not this account is accurate, it is clear that Alexandria was the primary influence on Islamic alchemy The Islamic alchemists quoted Zosimos, Democritos, and Stephanos, as well as other Alexandrian alchemists such as Ostanes and Maria Prophetissa (second to third century often referred to as Mary the Jewess ). In addition, the Muslim alchemists also absorbed influences from Persia and Syria.
