Pierre Jean Fabre

Pierre-Jean Fabre (1588 – 9 January 1658) was a French doctor and alchemist. Born in Castelnaudary, France in 1588, he studied medicine in Montpellier, France. He became a practitioner of the iatrochemical medicine of Paracelsus. Beginning in 1610 he practiced medicine in Castelnaudary. He became famous as a specialist in the plague which was particularly severe in central Europe during the Thirty Years' War. Fabre prescribed chemical medications for the treatment of the plague and was at one time the private physician of King Louis XIII.

Fabre was a practising alchemist, and claimed to have succeeded in the alchemical transmutation of lead into silver on 22 July 1627. He was strongly attracted to mystical aspects of chemistry, drawing parallels between the chemical operations of alchemy and the sacraments of the Christian church, particularly in his Alchymista Christianus (1632).

Fabre died in Castelnaudary on 9 January 1658.

Alchymista Christianus "He saw valid correspondences between the sacraments and chemical operations: calcination symbolised penitence; fire and water corresponded to baptism; and the Philosopher's Stone could be compared to nothing less than the Eucharist. Assuming this, Fabre thought that true alchemists were like priests; the spirit of mercury was like the angels; the earth was like the Virgin Mary; and the life-giving properties of salt gave it a valid connection to Christ. These correspondences could be visualised because they were sculpted on the great churches of France, whose artist-architects had presented their esoteric knowledge to the viewer." -
