Herodotus was an ancient Greek historian who lived in the 5th century BC (c.484 BC – c.425 BC). He is regarded as the “Father of History” in Western culture. He was the first historian known to collect his materials systematically, test their accuracy to a certain extent and arrange them in a well-constructed and vivid narrative.
This is a tale that Herodotus learned in Egypt and many believe that this anecdote was told to him by Egyptian priests, claiming it a true story. Herodotus, himself, didn’t actually believe this particular story but he felt it was his duty to report what he was told.
