This phrase probably derives from Aesop's fable of the lion, the fox and the ass. The three went hunting and killed a stag. The ass divided it into equal proportions, but the lion as king of the animals looked upon this as an insult and killed the ass. The fox, more craftily, nibbled a bit and left the 'lion's share' to the bigger beast. In fact, a lion does get the largest share of the food obtained for him by the lionesses. The phrase is recorded by 1790.
