This is an excerpt from my longer blog post about the Lovers card:
For my Lovers pendant, I used the interlocking, DNA-like snakes to symbolize passionate love (& to reference the Biblical references to Eden in the Smith-Waite deck as well as the snakes on the Minor Arcana Two of Cups). Above the interlocking snakes is a winged Sun, embracing the Moon to reference the alchemical marriage of silver & gold and the product of their marriage, the hermaphroditic rebis.
On the reverse of the pendant is a sigil of two (or is it four?) triangles, one pointing up and one pointing down, Fire & Water. Within the triangles is a sideways glyph of Mercury. Arranging Mercury’s glyph on its side makes it appear as three parts: the cross of matter, the Sun’s glyph, and the Moon’s glyph. Above this is the Zodiacal symbol for Gemini.
