Galleria dei Carracci (Loves of the Gods)

The first great fresco of the Baroque era — the vault of Palazzo Farnese covered in mythological scenes in an illusionistic framework that directly inspired Rubens, Poussin, and every Baroque ceiling that followed. Winckelmann ranked it alongside the Sistine ceiling and Raphael Rooms as one of three supreme achievements in Rome. Free: book via ambafranceitalie.it (Mon 15:00, Wed 17:00-19:00).
