The parable of the blind men and an elephant originated in the ancient Indian subcontinent, from where it has been widely diffused. It is a story of a group of blind men who have never come across an elephant before and who learn and imagine what the elephant is like by touching it. Each blind man feels a different part of the elephant's body, but only one part, such as the side or the tusk. They then describe the elephant based on their limited experience and their descriptions of the elephant are different from each other. In some versions, they come to suspect that the other person is dishonest and they come to blows.

Proverbidioms is an oil painting by American artist T. E. Breitenbach depicting over 300 common proverbs, catchphrases, and clichés such as "You are what you eat", "a frog in the throat", and "kicked the bucket". It is painted on a 45 by 67 inch wooden panel and was completed in 1975 after two years work, when the artist was 24.
