Xylospongium was used by the Romans to clean the anus, the Americans made it a device for cleaning the toilet.
Xylospongium or tersorium, also known as a sponge on a stick, was a hygienic device used by the ancient Romans to wipe the debris from the anus1, consisting of a stick (Greek: ξύλον, Xylon) and a sea sponge (Greek: σπόγγος, sponge) attached to one end of it.
Tersorium was common to all people using the public latrines. To clean the sponge, the user rinsed it in a bucket of water and salt (or vinegar)2. Needless to say, this “hygienic” device became a breeding ground for bacteria, causing the disease to spread – especially in military camps3. Fortunately, the Americans transformed Xylospongium into an irreplaceable toilet brush, and the Romans still have a passion for washing the perineum area, but they do it using a more hygienic bidet, which is equipped in every toilet in Italy.
