Having drawn our attention from the celebration, to the detail of the painting of the Santa Maria, I must admit my attention has also wandered to three other visual anomalies in the room....from the bend in the chimney flue, to the curving edge of the grand piano, and back to the corner, to what is apparently an exposed section of brick wall bordered by curved plasterwork. But the rest of the group seems unperturbed, and immersed in the music! I'm wondering what titles they were treated to.
