We’ve all been on tours where the guide has an impressive spiel that covers the waterfront without revealing the complexity below the surface. Roberta’s tour of Ravenna is the opposite. The architecture and the mosaics of Ravenna are marvelous in and of themselves, but to delve into the theology, ancient history, politics and culture underlying the graphic depictions of Christian salvation history enriches the visual experience. Roberta’s warmth, depth of knowledge and willingness to answer our endless questions made our half day with her the highlight of our trip to Ravenna and Italy as a whole. Grazie, Roberta!
