Query: Remarkable insight into a uniquely martial people.

Pressfield has done some fine research not only into the military and social history of the period and the peoples, but he provides an unusually perceptive insight into a uniquely martial people, the Spartans. In Gates of Fire, Pressfield has set a standard of hoplological understanding and excellence that few specialist non-fiction writers achieve, never mind novelists. We congratulate him on an excellent piece of work on the Greek warrior, the hoplite.
