There were two groups at the Brancacci chapel whilst I was there: A group of Germans and a group of Italian 12-year-olds from Ferrara. The kids were neither listening nor looking at the frescoes. Most were busy playing with their mobile phones. I asked their teacher why he had brought his class to the chapel and he told me that kids had actually learned about the chapel and the frescoes at school.
The Germans were very serious and asked questions. Their poor guide, after the third question that she was unable to answer, explained that she had mislaid her papers:“Ich bin ziemlich irritiert da ich meine unterlagen verloren habe. Da verlieren wir halt alle.”
