One of the ideas of the alchemy is that every human being is a hermaphrodite – within every man there is a spiritual woman and within every woman there is a spiritual man. In addition, there is also a dragon. Every ordinary man leads a dragon and every man must eventually slay that dragon. In alchemy the Sun-male is often called the King and the Moon-female – the Queen. The King and the Queen together are sometimes as lovers, sometimes as a hermaphrodite. It’s a symbol of harmony, whole man and whole woman.
The symbols of the four elements: Air as a chameleon (in medieval times it was believed that the chameleon ate only air) or the form of a bird; Fire as a salamander; Water as a fish, sometimes as water flowing in a stream or from a water jug; Earth as a squirrel. Spirit and soul were often visualized as linked with Water, while the body was associated with Earth.
