He lived during the 5th century BCE and authored the work "Histories," which provides a detailed narrative of the events, causes, and outcomes of the conflicts between the Greek city-states and the Persian Empire. Herodotus's writings are significant not only for their historical content but also for their storytelling style and method of inquiry. He sought to provide a comprehensive account of the past, incorporating geography, customs, and the perspectives of various cultures, making his work foundational in the study of history.
