The ancient Greeks revered so much history, that they have assigned a muse (Clio) to the concept of history.Originally the meaning of this term involves research (analysis) and communication of its results.
Herodotus was the first to point out that the history is of terrible importance to after-ages, and it has an instructive role. Belgian historian Léon Halkin said that “the history of human knowledge helps. History is like the earth on which we live.”
Herodotus’ effort was devoted to elucidating the causes and conduct of the medic wars (490-479 BC) a laborious investigation, which make equally spatio-temporal conditions of the flowering of Greek civilization.
