The spiritus mercurialis and his transformations represented as a monstrous dragon. It is a quaternity, in which the fourth is at the same time the unity of the three, the unity being symbolized by the mystagogue Hermes. The three (above) are (left to right); Luna, Sol, and coniunctio Solis et Lunae in Taurus, the House of Venus. Together they form ☿= Mercurius.
