Sources for writing a book on the Greeks

[Timoleon]

Check the EB Bibliography. It has a lot of interesting books there. I would suggest to start with
Alexander to Actium: The Historical Evolution of the Hellenistic Age by Peter Green. It's a great overview of the whole era.

Good luck and please let us know when you finish the book.

What I would recommend you do is read through a few books that the description of your planned book in accessibility and size - "The Greek World After Alexander" by Shipley and "The Hellenistic World" by Walbank come to mind - and see if you can present anything new or in an improved manner.

Why non-fiction necessarily? There are in fact many very good books, by eminent and respected scholars with intimate knowledge of the language and period acquired over many many years, which (no disrespect intended)) you will find hard to equal, much less better. And still most people have never heard of Seleucus. So, if you want to make Antiochius, Seleucus et al as famous and popular as Caesar, Caligula and Nero then you need to write a good novel, screenplay or best of all a graphic novel. Why don't you do a Xenophon comic, or write a novel about Iphicrates? Just think, where would Tiberius Claudius Drusus Nero Germanicus be without Robert Graves?
