Plate 9 of Khunrath Heinrich's (1560-1605) Amphitheatrum Sapientiae, purportedly one of the most significant books of theosophical alchemy and the occult sciences. Though the title page reads 1602, the book was not published until 1609. Erasmus Wohlfahrt edited and published the manuscript following Heinrich's death in 1605. Wohlfahrt also added a preface and conclusion. The work contains masterful engravings, remarkable for their execution as well as alchemical symbolism. Nine double-paged copperplate engravings, a title page, and a frontispiece can be found in the digital collections.

The engraving depicts a mountainous landscape in which the focal point is a large mountain or volcano emerging from a river. The face of the mountain is inscribed with text, and a group of men are depicted in front of the mountain regarding the message.
