The elixir of life, also known as elixir of immortality and sometimes equated with the Philosopher's Stone, is a mythical potion that supposedly grants the drinker eternal life and/or eternal youth. This elixir was also said to be able to create life. Alchemists in various ages and cultures sought the means of formulating the elixir.
The search for the Elixir of Life has been the supreme quest for many. In medieval times, there are accounts of the alchemists looking for the philosopher’s stone, believed to be required to create the elixir but also to convert lead to gold. Bernard Trevisan, an alchemist of the 15th century said that dropping the philosopher’s stone into mercurial water would create the elixir, and we have multiple cases of alchemists that allegedly found the Elixir of Life including the infamous Cagliostro or Saint Germain.
In Greek mythology, the elixir was known as ambrosia and it was said that ambrosia was used by the gods to cure diseases, fix scars, and make the body beautiful again. If dead people would be treated with ambrosia, their bodies would remain in perfect condition forever. In other references, we can see that ambrosia was abundant in the gardens of Hesperides. Hesperides were nymphs who tend to a blissful garden in the far western corner of the world, a place where ambrosia was brought to the god Zeus.
Despite appearing in other mythologies, the immortal substance also appears in the Bible where we can see similarity between the gardens of Hesperides and the gardens of Eden, where according to the Old Testament, man was forbidden to eat the fruit from the Tree of Life. When Adam and Eve ate from the Tree of the Knowledge of Good and Evil, it appears that God alerted other deities to be on alert because man should not eat also from the Tree of Life and become immortal like them. This could imply that the elixir was first created during Biblical times, and was likely concocted through the use of the Forbidden Fruit, as the substances inside the fruit itself was used to created the elixir.
The Elixir grants the drinker an indefinitely extended life, for as long as they keep drinking it regularly, though, the frequency with which it needs to be consumed (along with its entire creation process) is unknown. Any person who relies on the Elixir will die if they cannot obtain more Elixir before the last quantity imbibed wears off.
The Elixir also has the ability to somehow reincarnate a disembodied yet earthbound soul, mostly due to the powerful magical, life-based properties. However, the Elixir does not make the drinker truly immortal, but only lengthens the lifespan. For example, an alchemist and his wife lived for little over six-hundred and sixty years because of this elixir, but eventually died when their supply of Elixir was subsequently depleted.
