Palindromes.

A palindrome is a word or phrase which reads the same in both directions. The word "palindrome" was coined by the English playwright Ben Jonson in the 17th century from the Greek, meaning running back again. Some examples are: RADAR, POP, MADAM, LEVEL, EYE.

Palindromes as a form of wordplay have been created for many centuries. For example, the ancient Greeks are known to have often inscribed the following onto their fountains. The Romans were also admirers of palindrome.
