The discovery of this spring led Romans to build an aqueduct which, as was the tradition of the time,\\nended with a fountain. And so the Trevi Fountain was built. \\nThe monumental fountain we admire today was built in the 18th\\ncentury by an obscure character named Nicola Salvi. It took 30 years to built and ended up ruining Salvi's health. He died unable\\nto undertake other projects and without seeing his beautiful fountain completed (the work was finished by Pietro Bracci). One of\\nthe Trevi Fountain's most outstanding features is the contrast between the fountain's overwhelming grandeur and its location amid\\nnarrow alleyways and tiny squares. It was intentionally designed to elicit a surprise from tourists, most of whom are no doubt\\ndeeply impressed when they come face to face with it. \\nWhat I want to talk about, though, are the statues: at the top, the papal\\nshield stands between two winged figures playing trumpets. Below, there are sculptures representing the four seasons and the\\ncyclical nature of time. On either side of the main figure, there are two reliefs that depict the story of Agrippa’s soldiers discovering\\nthe spring with a dowsing rod and Agrippa ordering the construction of the aqueduct. \\nTwo other large statues tell of the benefits of\", metadata={'source': 'italy_travel.pdf', 'page': 4})])]}"
