While strolling down the Gallery of Maps in the Vatican Museums, a seemingly interminable corridor displaying frescoed maps of the Italian landscape, it is easy to feel disoriented. Dizzy, even. The gallery is 395 feet long, over the length of a US football field, and contains forty brightly painted topographical maps of the regions of Italy, each one embellished with intricate details such as compasses, sea creatures and ships. The ceiling is no less spectacular, a barrel vault decorated with stucco, gold leaf, grotesques, and frescoes depicting stories from the lives of the saints. Windows to the right afford breathtaking views of the Vatican Gardens. It is almost too much for the eye to take in.
