I have often heard the expression, the lion’s share, but I didn’t know that it is part of Aesop’s Fables. Nor did I know what Aesop meant by it. I thought it just meant: the biggest part of what is being shared. But if you read this, The Lion’s Share. Aesop. 1909-14. Fables. The Harvard Classics, you will see there is a bit more to the fable.
Once you check that out, poke around and you can find more of Aesop’s Fables.
