Palazzo Barberini holds two staircases by two rivals, and climbing both is the point of coming. Bernini's is a square stairwell of straight flights, wide and stately, built so that a guest coming up could be watched from below. Borromini's is a tight helix carried on paired columns, and each turn is a little smaller than the one beneath it, so the shaft seems to run further up than the roof allows. The two men were rivals for forty years, and here their work stands a two-minute walk apart.
Upstairs the rooms hold the national collection of older painting. Raphael's portrait of a woman wears a bracelet with his name on it; Caravaggio's Judith kills a man with a look of distaste on her face; Holbein's Henry VIII was painted for a marriage negotiation. The great salon between them has a ceiling by Pietro da Cortona in which the family's three bees fly up into an open sky. The palace went up between 1627 and 1633 for the family of a reigning pope, and for a collection this good it gets very few visitors.
