I've been wondering how would a novel or series of novels set in an ancient era fare. All fantasy I've read is set in a medieval setting. How would you feel about a fantasy with the culture of Rome and Greece? The map would be similar, though maybe not as blatant of a rip-off as Martin's is of Great Britain. Is "stealing" from history considered a form of plagiarism? I am very interested in all that's happened back then, but I want to put it in my own world so I'm unrestricted by factual events. There would be fantastical beings and heroic humans who are difficult to kill, but I'm inclined to eschew Greek and Roman mythology and put a light version of my own. So...any thoughts?
