The bigger they come...

Anyone know the origin of the phrase "The bigger they are the harder they fall"?

The saying is old and the idea is ancient. Traced back to "Dives and Pauper" by H. Parker. Current form attributed to British-born world heavyweight boxer Bob Fitzsimmons (1858-1917). Random House Dictionary of Popular Proverbs and Sayings by Gregory Y. Titelman (Random House, New York, 1996). Page 30. Source 2 points to the David and Goliath story in the Bible and, 2,300 years ago, The Histories of Herodotus: "It is the gods' custom to bring low all things of surpassing greatness." The Dictionary of Cliches by James Rogers (Wings Books, Originally New York: Facts on File Publications, 1985). Page 25.
