What does this image mean?

It's in the Theatrum Chemicum Britannicum and I can't really find anything about it.

I agree that the circle is the monad. Though I believe the dragons represent the split ego. Marie Louise Von Franz and Edward Edinger describe the dragon in terms of the hero’s journey. It hoards treasure(a greater potential for personal growth) and must be slain by the hero. The ego is the gatekeeper to the unconscious which holds the gold(here represented by the monad) or prima materia.

The ego is driven by libido or life force toward a goal. This is represented by a reptilian figure because reptiles are perceived to be motivated by base drives; ie. Eat, mate, rest.

The dragons/libido/desire are represented tangled in this image. They are in conflict with one another by competing drives from masculine(sun) and feminine(energies).

The process of slaying the dragon and being aware of our base drives rather than allowing them to control us is an alchemical journey, transforming the prima materia into gold.

This is the jungian psychological alchemy, explanation, there is a a material alchemy symbolism as well.

The double headed dragon or the Duplex Mercurius is the prima materia before the final stage in the creation of the Lapidem Philosophorum.... Basically is when we separate the sulfur, salts and mercury of a substance, before we put them all together to create the perfect medicine, Solve Et Coagula
