The Histories of Herodotus is now considered as the founding work of history in Western literature. Written from the 450s to the 420s BC in the Ionic dialect of classical Greek, The Histories serves as a record of the ancient traditions, politics, geography, and clashes of various cultures that were known around the Mediterranean and Western Asia at that time. It is not an impartial record but it remains one of the West's most important sources regarding these affairs. Moreover, it established without precedent the genre and study of history in the Western world, although historical records and chronicles existed beforehand.
