"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." - (en.wikipedia.org 10.08.2021)
