In the Baptistery of Giovanni delle Fonte, appended to the Naples cathedral (or, rather, the cathedral appended to it), there are some wonderful 4th century mosaics in the ceiling. The four evangelists are represented by their symbols, and the best preserved is the lion that symbolizes St Mark. They’re rare examples of Paleo-christian art. Later in November I’ll be returning to Ravenna to see more mosaics. Can’t wait.
