Greek term, xylon, wooden stick and spongos, sponge, which the Romans also called tersorious, tergeo, drying, rubbing, cleaning. A stick with a sea sponge at one end with which the Romans wiped their ass in public latrines. Thus they shared all the gut bacteria even though they left it in a dissolution of water, vinegar and salt. In issue 70 of the Letters to Lucilius in which he speaks of suicide, Seneca refers to this instrument in these terms : . . . lignum id quod ad emundanda obscena adhaerente spongia positum est . . . ( the stick located in the latrine to clean the droppings ).
