Fountain in Piazza Santa Maria in Trastevere mentioned in documents dating to the second half of the 15th century. A drawing of the fountain appears on the map of Rome made by Pietro del Massaio in 1471, along with a description of the legend of the fountain's origin. According to the legend, which appears in the "Chronicle" of Eusebius, translated and finished by Saint Jerome in the fifth century, on the night of the birth of Christ a fountain of oil appeared miraculously in front of the church, which as a result was given the name "Santa Maria in fontibus." The original fountain was supplied with water
Taddeo Barberini Taddeo Barberini Taddeo Barberini (1603–1647) was an Italian nobleman of the House of Barberini who became Prince of Palestrina and Gonfalonier of the Church; commander of the Papal Army. He was a nephew of Pope Urban VIII and brother of Cardinals Francesco Barberini and Antonio Barberini. Thanks to their uncle's famous nepotism, the brothers shaped 17th-century Italian politics, religion, art, music and architecture. Barberini was born in 1603, the son of Carlo Barberini and Costanza Magalotti. He was the nephew of brothers cardinal Maffeo Barberini (later Pope Urban VIII) and Antonio Marcello Barberini (later also Cardinal) and of Lorenzo Magalotti.
