Herodotus(c. 484 BC – c. 425 BC) was an ancient Greek historian who was born in Halicarnassus in the Persian Empire. He is known for having written the book The Histories, a detailed record of his "inquiry" on the origins of the Greco-Persian Wars. He is widely considered to have been the first writer to have treated historical subjects using a method of systematic investigation—specifically, by collecting his materials and then critically arranging them into an historiographic narrative. He is often referred to as "The Father of History", a title first conferred on him by the first-century BC Roman orator Cicero.
