In the past two weeks I've been to Arezzo, Sansepolcro, Monterchi, Florence, Rome and Berlin. I've seen the Springtime in the Renaissance exhibition in Florence and the Titian exhibition in Rome. I spent two days in the print room in the British Museum, another two in the Kupferstichkabinett in Berlin and visited the Uffizi print room. Lots to write about - I'll be updating regularly over the next few weeks.
I try to travel at quieter times, and rarely go anywhere in summer (my reading season). I'm hoping to fit in a couple more trips over spring, and I'm already thinking about where to go in autumn. I'd love to get to the Piero della Francesca exhibition at the Frick, but I could just go to Williamstown another time to see the one painting in the show that I haven't seen before. The Durer drawings in Washington, on the other hand, is truly a once-in-a-lifetime opportunity. The Albertina is famously protective of its Durer watercolours; apparently you need a letter of introduction from Durer himself before they'll let you see them. I also want to see the Raphael drawings in the National Gallery's own collection.
