Quintus Horatius Flaccus, The Satires, Epistles & Art of Poetry of Horace…
“ XIII. To Vinius Asella. Ut proficiscentem. S I have told you oft, deliver these, My sealed-up volumes, to Augustus, please, Friend Vinius, if he's well and in good trim, And (one proviso more) if asked by him: Beware of over-zeal, nor discommend My works, by playing the impetuous friend. Suppose my budget, ere you get to town, Should gall you, better straightway throw it down Than, when you've reached the palace, fling the pack With animal impatience from your back, And so be thought in nature as in name Tour father's colt, and made some joker's game. ”
