Cervantes

Not everything that happens makes good telling, and there are things one could let pass untold without diminishing the story; there are acts that precisely because of their great consequences ought to be passed over in silence, and others so insignificant they shouldn't be mentioned. The outstanding thing about history is that anything written in it is made palatable by the taste of truth it brings with it. Fiction doesn't have that advantage, and its action must be prepared with such accurate details and good taste, and with such an appearance of fact, so that notwithstanding and despite its untruth, which unavoidably generates some dissonance in the mind, its structure may be truly harmonious.
