Out of the One comes Two, out of Two comes Three,
and from the Third comes the One as the Fourth.

–Axiom of Maria Prophetissa cited in C.G. Jung, Psychology and Alchemy. Collected Works, Vol. 12.

The “infans solaris” (solar infant) is the child of the hieros gamos. It is the ONE as the FOURTH birthed by the THIRD, in keeping with the ancient alchemical adage of Maria Prophetissa.
