From Antiquity To Enlightenment:

" While Herodotus sought to distinguish from myth and reality, as his predecessor Homer had not done, he believed that history should be written to not just inform, but take away from its boredom through entertainment. Herodotus cannot be said to make up the truth, although doctored it may seem for his purposes on occasion, he takes care in gathering primary sources to tell his stories. However, many criticize him in the future for his use of unaccredited sources, a rule later laid out by Plutarch who wrote, "[m]y fourth sign of ill will in history-writing is a preference for the less creditable version ." This is not to suggest that Herodotus was wrong but, however, it does show that he did not take care to adhere to the straight facts. .
             The second school of thought started in ancient times was by another historian, Thucydides. Thucydides criticized Herodotus heavily for his story-telling approach. He firmly believed that history was about fact, and nothing more. For Thucydides, written history was not to tell a story, but to inform through primary sources. Thucydides asserted that the most credible source is the account from the actual event itself. He explains that the only way to truly write about history, is to actually have lived the even itself. Since his works were primarily on the Peloponnesian Wars, which he participated in himself, it was easy to entrench himself in this doctrine. "Compared to Herodotus, Thucydides shows a much sharper focus, narrower horizons, and a more critical attitude toward truth." .
             While Antiquity was a marvel in the advent of written history, it was far from perfect. It would not be until the Medieval period that Herodotus" and Thucydides" purposes of writing history would take a turn to a more religious bias. During this period one historian sticks out more than any of the others. Josephus Flavius, followed by Augustus and Bede, would make a transformation from writing history as a story or informative essay on Grecian self-history to history as a written record to the greatness of God.
