Historically, the ring finger on the left hand was believed to have a vein, the vena amoris (vein of love), that directly connected to the heart. This belief is now understood to be inaccurate from a scientific perspective. However, the tradition of wearing wedding rings on this finger persists due to this historical association.
Beyond this historical association, there isn't a single finger that definitively represents the heart. Different cultures and contexts employ various symbolic gestures:
-
The Korean finger heart: This gesture, formed by crossing the thumb and index finger to create a heart shape, symbolizes love, affection, and friendship. This is a modern, widely recognized symbol unrelated to the historical "vena amoris" belief.
-
Pointing to the chest: When experiencing chest pain, one might instinctively point to the area of discomfort with a finger to indicate the location of cardiac symptoms, as seen in the Mass General Brigham article. This isn't a symbolic representation, but rather a practical indication of pain location.
While some might associate a finger with the heart through personal symbolism or cultural practice, there's no universally accepted single finger representing the heart. The historical belief concerning the ring finger and the modern Korean finger heart gesture are notable examples of this varied association.
