Place of Thucydides in ancient historiography

Thucydides defined an important moment in ancient historiography. His work on the Peloponnesian War represented a significant departure from the work of Herodotus. He rejected the story-telling narrative of his predecessor in favor of a more analytical reporting of his chosen subject. He stated explicitly what has been termed "the Thucydidean method," which embraced personal experience, eyewitness testimony, personal investigation of location, a commitment to verifiable facts, and an acute inquiry into the human psychological and political underpinnings of causation. He at times offered authorial judgments on events, but his narrative style was calculated to enable the reader to come to his own conclusions. His impact on the subsequent historians of Greece and the Roman Republic and early Empire was considerable.
