How does the author use language in the novel, The Tyrant’s Tomb?

The language of the novel splits between traditional Roman customs and modern day words. The legion of Camp Jupiter uses terms such as centurion, cohort, and legionnaire. A few of the characters say certain words in latin, but Apollo always translates them for the reader (or, in the case of swear words, simply implies that it was said). They also use the roman names for all of the gods, such as Diana instead of Artemis, Jupiter instead of Zeus, and Mars instead of Ares. Apollo occasionally shifts between the two names, but usually corrects himself as not to confuse the reader. Furthermore, due to Apollo’s nature as an ancient and formally divine being, he has a vast vocabulary that is occasionally offset with his forgetfulness. But the author provides plenty of context clues, or has Apollo define them himself, if needed.
