The transition of the human heart symbol from an anatomically accurate depiction to the more stylized, emoji-like heart we recognize today has a complex history that spans centuries. The heart image we associate with romantic love was first depicted as a heart-shaped pear being shared with a lover, which appeared in the illustrated 13th century French work Li romanz de la poire (“Romance of the Pear”).
The Heart Offering from 1338-44 is considered the first distinctly stylised heart as representation of romantic love. Here (below) a woman gives her heart, shaped as we all know it today, to a man who holds his hand over his own heart.
In one of many pre-modern depictions of the agony of romance, a 1620 drawing from Stuttgart titled “The Contortionist Lover,” shows a woman goading her tortured partner with a heart on a stick:
Interestingly, not only was this stylised depiction of a heart created within the romantic love tradition, but so too was the emblem of a broken heart which appears below in an allegorical depiction of women’s power over men’s hearts (woodcut, 15th century by Master Casper von Regensburg, Berlin, SMB, Kupferstichkabinett) – titled “The Power of Minne.”
