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.
Trevi Fountain (Fontana di Trevi). The central figures of the fountain are Neptun (God of the sea), flanked by two Tritons. One struggles to master a veru unruly sea horse, the other lead a far more docile animal. These symbolize the two contrasting moods of the sea.
