What is the main setting in the novel, The Thief?

The action of the novel takes place in settings reminiscent of ancient Greece, but the atmosphere surrounding the characters feels like medieval Europe. There are references throughout the story to historical happenings of the fourteenth, fifteenth, and sixteenth century such as the bubonic plague, gunpowder, the printing press, and pocket watches. The author subtly interweaves these historical occurrences into her tale of fantasy to provide an underlying link to reality.
