The Romans believed that the liver was the source of human emotion.
The ancient Hellenes may have known, as evidenced via the myth of Prometheus, that the liver can regenerate from damage.
In the myth of Prometheus, His liver is eaten by a large bird. (Depending on the regional variant, the exact bird may differ.)
Via Aristophanes, Eros is the father / creator of all birds.
From this, we can say that when Love leaves our emotions damaged, we can still heal. Or, if you prefer, Love alone won’t leave us irreparably damaged.
