The translation of hundreds of classical Greek texts into Latin was commissioned by the scholarly Pope Nicholas V who led the Church in Rome from 1397 till 1455. It was imperative for him to embellish the city of Rome to make it worthy of being called the capital of the Christian world. Beginning in 1453, the ruined ancient Roman aqueduct known as the Aqua Vergine which had brought clean drinking water into the city from eight miles away, underwent repair at the bidding of the Pope. Building a mostra, a grandiose celebratory fountain built by ancient Romans to memorialize the entry point of an aqueduct, was a custom revived by Nicholas V. The architect Leon Battista Alberti was commissioned by the Pope to put up a wall fountain where we now see the Trevi Fountain. The Trevi Fountain as well as the well-known baroque fountains located in the Piazza del Popolo and the Piazza Navona were eventually supplied with water from the water fountains solar powered altered aqueduct he had reconstructed.
