medieval anatomical drawings featured heart shape
while the silphium theory is compelling, the true origins of the heart shape may be more straightforward. scholars such as pierre vinken and martin kemp have argued that the symbol has its roots in the writings of galen and the philosopher aristotle, who described the human heart as having three chambers with a small dent in the middle.
according to this theory, the heart shape may have been born when artists and scientists from the middle ages attempted to draw representations of ancient medical texts. in the 14th century, for example, the italian physicist guido da vigevano made a series of anatomical drawings featuring a heart that closely resembles the one described by aristotle.
since the human heart has long been associated with emotion and pleasure, the shape was eventually co-opted as a symbol of romance and medieval courtly love. it grew especially popular during the renaissance, when it was used in religious art depicting the sacred heart of christ and as one of the four suits in playing cards. by the 18th and 19th centuries, meanwhile, it had become a recurring motif in love notes and valentine’s day cards
