Engraved image of the Emerald Tablet from Heinrich Khunrath's Amphitheatrum Sapientiae Aeternae (1609). The Emerald Tablet (Tabula Smaragdina) is the foundational Hermetic text containing the formula "as above, so below," which Tomberg identifies as the basis of the method of analogy in Meditations on the Tarot.
