ALCHEMY - TREE OF THE MOON - HERMAPHRODITE Engraving from Johann Daniel Mylius, Philosophia Reformata, 1622. The presence of the Tree of the Moon, or the Arbor Argentum, along with the fact that the hermaphrodite stands on a crescent Moon, indicates that this stage is the alchemical process marking the perfection of the First Silver. The hermaphroditic merging of the King and Queen indicates that the process is not yet complete, as integration has not taken place.
