An intricate seventeenth-century engraving from Heinrich Khunrath's "Amphitheatrum sapientiae aeternae," depicting the "Gate of the Amphitheater of Eternal Wisdom." On the left, a radiant sun with beams of light illuminates a sheer mountain cliff. The cliff face is inscribed with Latin and Greek text. At the bottom of the cliff, two figures in early modern attire stand in discussion. To the right, the cliff forms the entrance to a dark grotto or cave. Inside the entrance, a series of inscribed tablets or rays are arranged in a circular pattern around a central point of light. Within the cave, a solitary figure is shown walking toward the light. A large block of Latin text at the bottom serves as a legend for the image.
Partial text on upper right cliff:
PROC [procession]
AB [from]
PRO [for/on behalf of]
Inscriptions on the left rock face:

Inscriptions on the tablets within the cave entrance:
