Palindromes

My weekly update from Schott's Miscellany tells me that Sotades of Maronea (c.275BC) is credited as one of the early inventors of the palindrome: words or phrases that read the same backwards as forwards. Some examples:

A man, a plan, a canal: Panama

Never odd or even

Are we not drawn onward, we few, drawn onward to new era?

Satan, oscillate my metallic sonatas!
