It’s been a long journey, by boat and foot, from your home in Constantinople to where you find yourself now: outside of the walls of the mountainous river city of Antioch. In the bright sunlight, you strain your eyes to catch a distant glimpse of the sight you’ve come all this way to see – and then suddenly, you do.
