The Trevi Fountain is the largest Baroque fountain in Rome and one of the most famous fountains in the world. The fountain has appeared in several notable films, including Federico Fellini's La Dolce Vita.
The fountain at the junction of three roads marks the terminal point of the 'modern' Acqua Vergine, the revived Aqua Virgo, one of the aqueducts that supplied water to ancient Rome. In 19 BC, supposedly with the help of a virgin, Roman technicians located a source of pure water some 13 km from the city (This scene is presented on the present fountain's façade). However, the eventual indirect route of the aqueduct made its length some 22 km. This Aqua Virgo led the water into the Baths of Agrippa. It served Rome for more than 400 years.
In 1629 Pope Urban VIII, finding the earlier fountain insufficiently dramatic, asked Gian Lorenzo Bernini to sketch possible renovations, but the project was abandoned when the pope died. Though Bernini's project was never constructed, there are many Bernini touches in the fountain as it exists today.
Competitions had become the rage during the Baroque era to design buildings, fountains and even the Spanish Steps. In 1730 Pope Clement XII organized a contest in which Nicola Salvi initially lost to Alessandro Galilei, but due to the outcry in Rome over the fact that a Florentine won, Salvi was awarded the commission anyway. Work began in 1732 and the fountain was completed in 1762, long after Salvi's death, when Pietro Bracci's Oceanus (god of all water) was set in the central niche.
The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
