Herodotus
Herodotus (c. 484 β 425/413 BC) was a Greek cultural scientist who invented the field of study known today as `history'. He is called `The Father of History' by the Roman orator Cicero for his famous work "The Histories".
Herodotus sometimes relays inaccurate information, but he was a human, and so not perfect, but his accounts have consistently been found to be reliable enough, and often the ONLY source at all. Early criticism of his work has been refuted by later archaeological evidence which proves that his most-often criticized claims were, in fact, accurate or, at least, based on accepted information of the time. In the present day, Herodotus continues to be recognized as The Father of History and a reliable source of information on the ancient world by the majority of historians.
