I am currently reading Joseph Campbell’s The Power of Myth, the conversation he had with Bill Moyers, and am fascinated by his thoughts on marriage:
“What is marriage? The myth tells you what it is. It’s the reunion of the separated duad. Originally you were one. You are now two in the world, but the recognition of the spiritual identity is what marriage is.”
While he hasn’t mentioned it yet, I know that he’s partly referring to the creation myth of the Earth Mother and Sky Father. Gaia and Cronus. Zeus and Demeter. Then later, the creation myth involving Adam and Eve.
These all involve unions between two figures that become or were once one. Again, the traditional definition of soul mates, the “other half” comes to mind. And the history of the idea begins to go back much further than I had initially expected.
