What is the author's style in Gates of Fire by Steven Pressfield?

The author lends Xeones a voice derived from Homer, justified by the character's early studies of the Iliad and Odyssey while in the mountains. The prose may seem thick and pompous as a result, but the intent is to create an atmosphere of ancient Greece. Another influence is the scribe, who likely substitutes synonyms for words that Xeones repeats too often. The scribe also admits to problems with certain translations from Greek to Persian.
