The Philosopher's Stone was the mythical substance in alchemy that was believed to cure all diseases and grant eternal life. This magical stone was the ultimate goal of many alchemists throughout history. In addition to promising health and longevity, it was also purported to have the ability to transform base metals into precious ones such as gold, known as the practice of transmutation. This speaks to the transformative spiritual and physical aspirations of alchemists as they sought universal enlightenment and wealth.
