Xylospongium

The xylospongium or tersorium, also known as a "sponge on a stick", was a utensil found in ancient Roman latrines, consisting of a wooden stick (Greek: ξύλον, xylon) with a sea sponge (Greek: σπόγγος, spongos) fixed at one end.

Academics disagree as to its exact use, about which the primary sources are vague. It has traditionally been assumed to be a type of shared anal hygiene utensil used to wipe after defecating, and the sponge cleaned in vinegar or water (sometimes salt water).^[1][2][3][4] Other recent research suggests it was most likely a toilet brush.^[5]

In the Baths of the Seven Sages in Ostia, a fresco from the 2nd century contains the Inscription (u)taris xylosphongio^[6] which is the first known mention of the term. Also in the early second century a papyrus letter of Claudius Terentianus to his father Claudius Tiberianus uses the term xylespongium in a phrase.^[7]

In the middle of the first century, the Roman philosopher Seneca the Younger reported that a Germanic gladiator died by suicide with a sponge on a stick. According to Seneca, the gladiator hid himself in the latrine of an amphitheatre and pushed the wooden stick deep into his throat.^[8]
