The Hermetic Philosopher, or Master Key

An engraving depicts two men working in a rugged, mountainous landscape. One man uses a pickaxe to dig into the rocky soil, while the other raises a heavy hoe high above his head to strike the earth. In the distance, a solitary figure sits peacefully atop a high hill. A thin, vertical line descends from a bank of clouds toward the laborers, representing the descent of celestial influence or divine grace upon those who work.

An engraving shows a large building complex. The central house features a circular window containing a hexagram, known as the Seal of Solomon, positioned directly above an arched entrance. A person stands at this door, appearing to use a key to gain entry. To the right is a tall, round tower with battlements. On the left, a tree stands within a protected, fenced garden. A small crown is visible among the upper branches of the tree, representing the "Aurea Corona" or the successful completion of the alchemist's goal.
