“Which led Dastin, English, to say of this Conjunction: If the White Woman is married to the Red Husband, they will embrace each other immediately, will join, will couple together, and will form only one Body by their Dissolution. This Copulation is the Philosophical Marriage, and the indissoluble Bond. This is why it is said; These Two become One by conversion, and hold by One, namely by our Mercury, which is the Ring of the sovereign Link; Also he is called The Daughter of Plato, who unites the Bodies assembled by love.” - Bernard Trevisan. Verbum Dismissum
Alchemical marriage represented as a planetary conjunction: A chain links Mars and Venus (a syzygy). Mercury, the agent of joining, sits between the opposites as the mediator. A solarized filius philosophorum, the 'child of the Work', is displayed in the middle, representing the new substance born from the joining of the two opposing principles. It is a 'third thing', the 'reborn sun' or 'new king,' the 'philosophical child' born out of the lunar state and then becoming solar.

Mysterium Coniunctionis
"Mysterium Coniunctionis - “mystery of union” or “marriage.” An alchemical concept of great importance to Jung, referring to the wholeness created by the union of opposites in the psyche, symbolized by but not limited to the joining of male and female."
- The Jung-White Letters, footnote 55, p. 185
"The spirit surrounds life as fire surrounds wood. The marriage that is made must stand firm and unshaken. It reforms all corruption back into goodness, When the heavenly spirit holds both bonds together. Since union binds what was two into one, By one and the same spirit alone." “What God has joined together, let no man separate. And unless one is born again of water and of the Holy Spirit, he shall not enter into the Kingdom of Heaven.” - Alchemical treatise, 16 Century, Cambridge
