The Romans did not have toilet paper. Instead they used a sponge on a stick to clean themselves.
In this regard, how old is the toilet paper?
Paper became widely available in the 15th century, but in the Western world, modern commercially available toilet paper didn’t originate until 1857, when Joseph Gayetty of New York marketed a “Medicated Paper, for the Water-Closet,” sold in packages of 500 sheets for 50 cents.
