It is summer, and the whole world seems made of brass: the wooden ship, the golden sea touched by the setting sun, and on the far horizon, the towers lining the shore. You have traveled across land and water, faced hunger, piracy, and betrayal, and now, on this small, creaking ship, your journey to Byzantium is nearly at an end.
