Sample text

The leading Islamic alchemist was Jabir ibn Hayyan, who was active in the 8th century AD. However, his numerous books do not necessarily all have Jabir as their author. Many of them may in fact have been written by others but attributed to Jabir because his great fame and authority as an alchemist reflected credit on them. A number of Jabir’s books, the most important one being his Summa Perfectionis, were translated into Latin. At the same time, his name was latinized to Geber and as “Geber, the most famous Arabian Prince and Philosopher”, he came to dominate the alchemy that now began to flourish in medieval Europe.

Characteristically enough, he soon found himself in acrimonious conflict with one of the councillors of the city over fees for medical services, and he resumed his incessant travelling. He had completely rejected classic medicine and denounced its great figures in the past, with the exception of Hippocrates whom he saw as having been misrepresented by Galen and Avicenna. But what were his own views? What had he to offer instead of the all-explaining theory of the four body fluids? Paracelsus took the view that sickness and health could be explained, not by the relative proportions of the body fluids, but in terms of three chemical principles: sulfur, that signified combustibility; mercury, that symbolized fluidity and changeability; and salt that stood for solidity and stability.

He even burnt some of his manuscripts and left his chair in anatomy at Padua to become court physician to the Spanish King Philip II. The stiff formalism and bigotry of Philip’s court can hardly have been congenial to Vesalius. In 1564 he went on a pilgrimage to the Holy Land, possibly to reconcile himself with the Catholic Church whose wrath he may have incurred by his acid wit. On his journey the ship he travelled in was wrecked at the little island of Zákinthos where he took ill and died. There were a number of outstanding anatomists in Italy during the renaissance, men like Falloppio, Fabricius ab Aquapendente, and Bartollomeo Eustachi, but none of them can compare with Vesalius in importance.
