Who’d a thunk it? Google maps can now help you get more out of the preaching of the Fathers.
Check out the remarkable pages for The Seven Wonders of the Ancient World. The Pharos (lighthouse) at Alexandria, for example, is a place and a metaphor you’ll encounter fairly often. Cassian uses it metaphorically. So does Basil, in a warm tribute to his friend and correspondent Athanasius: “You see everything in all directions in your mind’s eye like a man looking from some tall watchtower, while at sea many ships sailing together are all dashed one against the other by the violence of the waves.”
