Walking to the top of the Acropolis, I notice only a quarter of the people that were here the first time. Iâ€™m not sure what has changed in the last week but itâ€™s a welcome sight. I pass the Odeon theater, which was built in 161 AD by Herodes Atticus as an indoor auditorium but over time has lost its wooden roof and is now used as an outdoor theater. More recently, the musicians Yanni and Sting, and the Greek singer Nana Mouskouri have all held concerts in it. Now, where to sit? I could spend at least a week up here drawing and painting. Let me check my trail mix supply.
