We draw it constantly. Children trace it on cards. Lovers etch it into trees. It flutters in text messages, glows in neon signs, hangs around necks. But the iconic heart symbol — the one that looks nothing like the four-chambered organ in our chest — doesn’t match anatomy at all.
So what is it, really?
Why do we keep pointing to the centre of the chest when we speak of sorrow, longing, love, or courage?
A Symbol Born of Shape, Not Science
The familiar heart shape dates back centuries. Its exact origin is murky. Some historians speculate it might derive from the shape of the silphium seed — a now-extinct plant used as both seasoning and contraceptive in ancient Cyrene. Its seed pods bore a resemblance to the modern heart icon, and coins from the region often show it.
Others believe it evolved from stylised depictions of ivy or fig leaves, both associated with fidelity and fertility in classical art. The curve of the heart shape mirrors the swell of hips, the parting of lips, the press of bodies. Even early anatomical diagrams, based on speculation or animals, may have played a part in standardising the form.
But its persistence can’t be reduced to botany or guesswork.
Archetype Over Accuracy
The symbolic heart doesn’t endure because it’s medically accurate. It endures because it works. It touches something. It stands in for a truth that’s older than anatomy: that love, vulnerability, courage, and grief feel like they live in the centre of the chest.
In Jungian psychology, symbols emerge not from logic but from the unconscious. They are expressions of things we do not yet fully understand, and perhaps never can. The heart symbol might be understood as an archetype — a visual condensation of an emotional truth. It bypasses language. It appears in dreams, scrawled in notebooks, glowing in neon.
It does not need to be precise.
It needs only to feel real.
The Heart as the Axis
In many esoteric systems, the centre of the chest is the axis of the human being. In Hindu and yogic traditions, it is the anahata chakra — the unstruck sound — associated with balance, compassion, and the bridge between the earthly and the spiritual. In Christian mysticism, the Sacred Heart radiates divine love and suffering. In Sufism, the heart is not a metaphor but the site of spiritual knowing.
Why the chest? Because when we hurt, it contracts. When we’re moved, it warms. When we feel a loss, we feel it physically — a hollowness, a pressure, a crack. The chest becomes not just the location of the heart, but the container of all its meanings.
This is symbolic thinking: mapping the invisible onto the visible.
Two Halves, Leaning In
Visually, the heart symbol is not just evocative of an organ. It also recalls two faces in profile, leaning in. Two bodies curled into one another. The shape is doubled, symmetrical, intimate.
It is not the image of a solitary being.
It is the image of unity. Of yearning for closeness. Of the mirror of the other.
This may be why we return to it instinctively. The child who draws a heart is not anatomically incorrect. They are symbolically exact. They are showing where the feelings go.
A Shape That Was Always Felt
It’s easy to imagine that the symbol came later — that first we had the heart, and only later did we stylise it.
But it might be the other way around. It’s possible that the symbol came first — an intuitive shape, drawn in the dirt or carved in stone — long before we understood the heart as a muscle. The idea of the heart as the seat of feeling predates cardiology by thousands of years.
We felt before we knew. We pointed to the chest. We drew a shape.
And meaning pooled there.
The Heart of the World
In alchemy, the heart was not just part of the body — it was a microcosm. The philosopher’s heart mirrored the structure of the cosmos. In medieval art, the heart was often shown being offered to God, or held in hand, or pierced by arrows of divine insight.
We still speak this way. To offer one’s heart. To open it. To harden it. To wear it on the sleeve.
These are not random phrases. They are symbolic echoes of something deeper: that the heart is not just a pump.
It is a place.
A centre.
A symbol that does not need to match the body to feel true to it.
Why We Keep Drawing It
The heart shape isn’t correct. But it’s not wrong, either.
It is curved and exposed. It is soft and pointed. It suggests presence and vulnerability, tenderness and direction. It says: here. It says: this matters.
The brain is clever. The gut is instinct. But the heart — the symbol — is what we give away. What we guard. What we trace, again and again, when words fail.
We made a shape for what we felt.
And it stayed.
Not because it was factual.
But because it was honest.
