Last week I was sent to Berlin for a few days on business, which meant that I was finally able to knock several major museums off my ‘to do’ list. I’d only been to Berlin once before, as part of a sixth form trip, during which our programme took us to the Reichstag, Checkpoint Charlie and Wansee but signally failed to consider anything pre-1933. In desperation, during a couple of hours’ free time when all the other girls went shopping, I begged my teacher and a hapless friend to come with me to the Gemäldegalerie, and my abiding memory of the entire school trip is standing in front of Caravaggio’s Amor Victorious, uncertain whether to be scandalised or delighted.
