The oldest Palindrome is called the Sator Square and reads:
"Sator Arepo Tenet Opera Rotas"
What makes this Palindrome especially interesting is that the letters of the first word form the first letters of all the words that follow. The words can therefore be written under each other, with the letters aligned, and then read horizontally or vertically, beginning either at the top left or the bottom right.
Other examples of palindromes:
Madam, I'm Adam
Was it Eliot's toilet I saw?
Was it a car or a cat I saw?
A Santa at Nasa
A nut for a jar of tuna
Some even include consistent spacing:
Rats live on no evil star
Step on no pets
Probably one of the longest palindromes ever is:
Dennis, Nell, Edna, Leon, Nedra, Anita, Rolf, Nora, Alice, Carol, Leo, Jane, Reed, Dena, Dale, Basil, Rae, Penny, Lana, Dave, Denny, Lena, Ida, Bernadette, Ben, Ray, Lila, Nina, Jo, Ira, Mara, Sara, Mario, Jan, Ina, Lily, Arne, Bette, Dan, Reba, Diane, Lynn, Ed, Eva, Dana, Lynne, Pearl, Isabel, Ada, Ned, Dee, Rena, Joel, Lora, Cecil, Aaron, Flora, Tina, Arden, Noel, and Ellen sinned.
