In arabe medieval alchemy, the main objective is to obtain a liquide substance called “Elixir”. This elixir permitted the transmutation of metals into gold. Sometimes, this substance is called “the stone”, the “illustrious stone’.
The Elixir not only transformed metals into gold, it was suppose to heal the sick and to prolong human life beyond natural years.
In Voltaire’s lettre to l’abbé Moussinot, Voltaire was of the opinion that such an interest would lead a man to financial ruins. For the average alchemist, the expense of such an enterprise would far exceed what revenues one could possibly ever earn.
Taken from mythology and alchemy, the mere elaboration of an hypothetical substance called ‘Elixir’, would constitute the goal of alchemy. The mere elaboration of it, would permit having an absolute conscience. To possess the Elixir itself, would permit access to the inextinguishable light; to give eternal life, or to transmute metals.
