Herodotus was an ancient Greek historian who lived in the fifth century BC (c.484 – 425 BC). He has been called the Father of History, and was the first historian known to collect his materials systematically, test their accuracy to a certain extent, and arrange them in a well-constructed and vivid narrative. The Histories-- his masterpiece and the only work he is known to have produced-- is a record of his inquiry, being an investigation of the origins of the Greco-Persian Wars, and including a wealth of geographical and ethnographical information.The Histories were divided into nine books, named after the nine Muses: the Muse of History, Clio, representing the first book, then Euterpe, Thaleia, Melpomene, Terpsichore, Erato, Polymnia, Ourania, and Calliope for books 2 to 9, respectively.
