Paul, where we all did use to go to touch the ancient chains that bound him and be cured of our distempers; I see the tomb of the disciple Luke, and afar off is the church wherein repose the ashes of the holy John, where the Christians of Ephesus go twice a year to gather the dust from the tomb, which is able to make bodies whole again that are corrupted by disease, and cleanse the soul from sin; but see how the wharves encroach upon the sea, and what multitudes of ships are anchored in the bay; see, also, how the city hath stretched abroad, far over the valley behind Pion, and even unto the walls of Ayassalook; and lo, all the hills are white with palaces and ribbed with colonnades of marble.
