I am not exactly sure what you mean. The field of history itself doesn't begin until the fifth century BCE with Herodotus and Thucydides. Both had unique styles and manners to convey the past or the current, in many cases. Historians like Xenophon broke ground in areas like anecdotal and biographical history. These Greek historians would be mimicked and studied by historians we would consider to be 'ancient.' One notable historian such as this was Procopius (6th Century CE), who wrote in a very similar manner to Herodotus. He used pre-battle speeches and deliberate omissions just as Herodotus did. It is important to keep in mind that these historians wrote about their contemporaries and events taking place during their lifetime.

I am not sure if this is what you were looking for and I am sure someone here can give you the answer you seek. My apologies if it wasn't helpful.
