Alfred Nobel intended that the prizes in his name be awarded for achievements that "have conferred the greatest benefit to mankind".
What exactly he meant by "the greatest benefit" is open to interpretation - and this year's awarding of the Nobel Prize for Literature to Bob Dylan joins a long list of controversial interpretations.
Many in the literary world were stunned when the legendary folk singer captured the world famous award.
Critics and purists cut quick and deep. "I totally get the Nobel committee. Reading books is hard," was one of the more humorous attacks.
The counter-attack was equally swift, citing a back catalogue charting the struggle for civil rights and dealing with many of the afflictions of modern life.
