Combine all of the ingredients, except the olives, mixing and kneading to form a smooth dough then fold in the olives., Cover the dough, and allow it to rise until it's doubled in size, about 90 minutes., Gently divide the dough in half; it'll deflate somewhat., Shape each piece of dough into a round loaf. Place each loaf on a lightly greased or parchment-lined baking sheet., Cover the loaves and let them rise until very puffy, about 1 hour. Towards the end of the rising time, preheat the oven to 425°F., Spray the loaves with lukewarm water, and make two fairly deep diagonal slashes in each., Bake the loaves for 25 to 30 minutes, until they're a very deep golden brown. Remove them from the oven, and cool on a rack.
