Once upon a time, there were three genders: male, female, and man-woman. These creatures were made of two distinct people, joined together at the back—four arms, four legs upon which they walked upright, one head on one neck with two symmetrical faces, separate sex organs, but all similar characteristics. These creatures were, as people tend to be, rather power-hungry, and because of their extreme strength and joint cunning, the gods grew worried that they would try to overthrow them, as the giants and Titans did. So after much consideration, Zeus came up with what seemed to him to be a reasonable solution: to cleave them in two, down the middle, and re-sew them up the back and to the navel, severing their strength and capabilities by half. If they were still too much to handle after this, he was prepared to again sever them, rendering them to hopping beings with one leg and one arm.
The gods were shocked to find that after the cleaving, the formerly joined pairs clung together, and refused to eat or sleep or do anything of use, so grieved they were to be separated from each other, until one of them or both of them eventually died. If one of a pair died, the other would then go wandering, searching for a like half—if the creature had been originally man/man, they searched for another man. Women/women halves searched for another woman, and man/woman survivors searched for their other opposite gender half until they found that lost half that they then joined with, as closely as they could without being one entity anymore. This feeling of “rightness” was like a riddle, and cannot be explained.
Not only does this myth quite neatly sum up the idea that no matter what shape or form it comes in (heterosexual or homosexual or anything in between), Love is the same idea, it also brings us another popular phrase, explained. Your “other half.” The idea that someone, somewhere, will fit you as surely as if you were split down the middle from the same original form and sent on your separate ways until you find one another. That, I believe, is what Love really is. As a friend of mine once said, it is finding someone “who fills a part of you you never knew was empty before.”
