The liver shows up in Greek mythology. Zeus was furious with Prometheus because he stole fire from the gods and gave it to humans. Zeus ordered Prometheus to be chained to a rock. Every day an eagle would peck out his liver and every night, the liver would regenerate.
The ancient people of the Near East and Mediterranean areas used sheep livers to tell fortunes, a practice known as haruspicy. Personally, I think palm reading isn’t as messy.
In the time of Plato, the liver was thought harbor dark emotions—rage, jealousy and greed. My goodness, everyone knows that the liver in a non-complaining organ.
The liver is mentioned in the sacred Jewish text, the Talmud. The liver is thought to store anger and the gallbladder counteracts the anger. This shows a fundamental lack of understanding about the liver. Not only does the liver remain silent, the gall bladder is a chronic complainer. In a relationship, the gall bladder would be like the quintessential stereotypical complaining wife; the liver would be the passive-aggressive husband, baiting the wife to blow up.
