Latin names (and a couple cultural differences) to change:
Troy - Troia
Gauls - Galli
Greece - Graecia
Greek - ok
(Spartan fleet - it's fine, just funny to read that! )

By the way, the Dictionary of Greek and Roman Geography on Perseus is potentially helpful, but a pain to navigate.

And the Dicitionary of Greek and Roman biography/mythology is a lot better but maybe not as much pertaining as the other site:

You're on the right track in general though for a first try. Try not to have too many paragraph breaks - but when you do have one use this: "\n" Like this: ...of this region\nIn bygone times... (that inserts a paragraph break for trait messages).
