Final answer:
Raphael worked primarily for the Vatican, under the patronage of Pope Julius II, where he created the Stanze di Raffaello in the Apostolic Palace.
Step-by-step explanation:
Raffaello Sanzio da Urbino, commonly known as Raphael, was a prominent Italian painter whose work was heavily commissioned by the Vatican, especially during the papacy of Pope Julius II. Most notably, Raphael was tasked with painting the rooms of the Vatican library, also referred to as the Stanze di Raffaello, where he created allegorical frescoes representing philosophy, theology, poetry, and justice. His engagement with the Vatican during this time was part of a larger cultural flourishing sponsored by powerful patrons, including families like the Medici and popes like Leo X and Clement VII, who commissioned other renowned artists such as Michelangelo.
