The Emerald Tablet is a short, cryptic text attributed to the ancient figure Hermes Trismegistus, often associated with alchemy and mysticism. It is believed to date back to the early centuries of the Common Era and is written in Arabic, Latin, and Greek. The tablet is famous for its statement, "As above, so below," which suggests a connection between the macrocosm and microcosm. The text is considered a foundational work in the field of alchemy, influencing many later thinkers and practitioners. It outlines the process of transformation and the pursuit of the philosopher's stone, a legendary substance said to turn base metals into gold and grant immortality.
