The manuscript that contains the history of the world written by Herodotus is known as "Histories." Completed in the fifth century BCE, this foundational work is often regarded as the first true history book. Herodotus, often termed "the Father of History," meticulously recorded the events of the Greco-Persian Wars and provided insights into the cultures, customs, and beliefs of various peoples he encountered. His method involved not only the collection of factual accounts but also the exploration of human behavior, politics, and conflict. "Histories" has had a lasting impact on historical writing, serving as a crucial source for understanding ancient civilizations and their interactions.
