I,heart.

The heart symbol.

What does it depict? There is some controversy.

It doesn't look much like a human heart, does look a bit like a cow heart, but does appear to closely resemble the following:

* turtle heart
* male prostate gland
* spread vulva/pubic mound/buttocks/breasts

But the most realistic explanation seems to be found in the seed of the silphium plant:


This is an ancient silver coin depicting the seed.

"The seeds are distinctly heart-shaped. Since this plant was widely used as an ancient herbal contraceptive or abortifacient, this shape may have come to be associated with sexuality and love."

Yes, the all-but universal sign of love, is just a way of telling your partner you can abort or avoid any unwanted foetus.
I guess these didn't make the cut.
