Palazzo Massimo alle Terme holds the paintings, mosaics and sculpture dug out of Rome itself, and the top floor is the best of it: whole rooms have been rebuilt indoors with their painted walls back around them. The finest is a windowless dining room from a villa that Livia, the wife of Augustus, owned north of the city. The paint was lifted off the walls in 1951 to save it. All four sides are painted as one unbroken orchard, with a low fence across the front and a wood behind, and nothing marks the corners, so the room seems to have no edges.
Botanists have counted more than twenty species in that garden, and every one of them is in flower and in fruit at the same time, which no real garden manages. Downstairs the collection turns to bronze and marble: a boxer sitting on a rock after a fight, his ears swollen and his hands still bound; a discus thrower; rows of emperors. The building is a Jesuit college of the 1880s with lifts to every floor, and it stays quiet even in the weeks when the rest of Rome is at its most crowded.
