Origin of the-straw-that-broke-the-camel-s-back

  • Possibly from the proverb, recorded by Thomas Fuller in his Gnomologia as "Tis the last feather that breaks the horse's back." This comes from an Arab proverb about loading up a camel beyond its capacity to move, to the scenario of a single straw of grass or hay overwhelming the desert-roaming beast of burden.
