Otho, Otis. Otto is a masculine German given name. It originates as an Old High German short form (variants Audo, Odo, Udo) of Germanic names beginning in aud-, an element meaning wealth, prosperity. The name is recorded from the 7th century (Odo, son of Uro, courtier of Sigebert III).
Construction of the Fountain. Already in the fifteenth century a small Trevi Fountain was built here during the papacy of Nicholas V. In 1732, pope Clement XII commissioned Nicola Salvi to create a large fountain at the Trevi Square to replace the existing fountain.
Perhaps most impressive of all, Roman aqueducts were so well built that some are still in use to this day. Romeâs famous Trevi Fountain, for instance, is supplied by a restored version of the Aqua Virgo, one of ancient Romeâs 11 aqueducts.
