The Royal Incest

The union of like with like, read as a symbol.

The Royal Incest: what does it mean in analytical psychology?

The royal pair of the alchemists are often brother and sister, and their union is an incest. It was over the reading of the incest motif that Jung parted from Freud: where Freud read it as literal desire, Jung read it in Symbols of Transformation as the libido’s turn back toward its source, in search of renewal, and in his essay on the transference as the union with one’s own kind, the joining of the psyche with itself.

The Royal Incest: where does it appear in myth and tradition?

Isis and Osiris, sister and brother, the sibling marriages of the pharaohs, Zeus and Hera, and the brother and sister of the Rosarium philosophorum.

From the Sources

Of Osiris' unions with his sisters, Jung writes that the sister is simply substituted for the mother as a legal, uncensured symbol, since marriage with a sister in early antiquity was not merely tolerated but commended.

“Both times with a sister who is simply substituted for the mother as a legal, uncensured symbol, since the marriage with a sister in early antiquity was not merely tolerated, but was really commended.”

Jung argues from the sun myths that the 'incestuous' desire aims not at cohabitation but at becoming a child again: at coming into the mother once more in order to be born again.

“…the fundamental basis of the "incestuous" desire does not aim at cohabitation, but at the special thought of becoming a child again, of turning back to the parent's protection, of coming into the mother once more in order to be born again.”

In the alchemical parable Silberer analyses, the bridegroom and bride are brother and sister, so bound by love that they cannot be separated, and so, 'as it were', wish to be punished for incest.

“Now I do not know what sin these two must have committed except that although they were brother and sister, they were in such wise bound by ties of love, that they could not be separated, and so, as it were, wished to be punished for incest.”
