Eduard Fraenkel (1888-1970), Horace
(1957; rpt. Oxford: Oxford University Press, 1970), p. 26:
Those kind readers who from time to time feel tempted to supplement a Horatian poem by reading into it what in their opinion the poet has failed to say himself are respectfully but firmly asked to shut this book and never to open it again: it could only disappoint and distress them. My interpretations are, without exception, based on the conviction that Horace, throughout his work, shows himself both determined and able to express everything that is relevant to the understanding and the appreciation of a poem, either by saying it in so many words or by implying it through unambiguous hints.
