The astrological symbol that you’ll most often find associated with the Lovers card in Tarot is the Sign of Gemini.
In a very superficial way, this association makes some sense. That is, The Lovers can conjure thoughts of two people (i.e., the number it takes to tango)…and Gemini also has to do with a pair of people. At a quick glance, then, these two symbols might seem to have a lot in common.
The similarities don’t really run all that deep, though. For one thing, when The Lovers refers to a pair of people, it’s often a pair of…well…Lovers. Meanwhile, Gemini refers to a pair of Twins. Siblings. Pretty much not lovers. The Lovers card doesn’t only refer to romantic/sexual bonds, but it certainly can. Gemini, meanwhile, is more about exploring information, communication, and interpersonal dynamics of a more detached nature. This isn’t usually the first Sign an astrologer will come up with if asked about romantic archetypes.
Of course, The Lovers is also about concepts such as choice and integration, and a case could be made for these notions to be good correlates for what Gemini is about.
Then again, cases could also be made in favor of entirely different astrological symbols being linked to The Lovers. Maybe something with a more Venusian feel. If not the Planet Venus itself, then maybe the Venus-ruled Sign of Libra would address the romantic possibilities of The Lovers, while also remaining relevant with respect to the “choices” meaning of the card…?
