Herodotus is widely credited as being the first historian—he traveled across Ancient Greece and wrote down what he saw and the stories he heard.
Classical scholar and poet Peter Levi said that what made him the first serious historian was his combination of great scope and precise focus, as well as his imaginative power as a storyteller and his rationalism, his concern with truth. However, while some call Herodotus 'The Father of History', others say he's actually 'The Father of Lies' and could've included more than facts in his tales.
