A bagnio (from Italian: bagno) was a term for a bath or bath-house. In England, it was originally used to name coffee houses which offered Turkish baths, but by 1740 it signified a boarding house where rooms could be hired with no questions asked, or a house of prostitution. The communication between master and slave and between slaves of different origins was made in Lingua Franca (also known as Sabir), a Mediterranean pidgin language with Romance and Arabic vocabulary.
