For if we consider attentively why men are pleased with metaphors we will find no other reason than that already stated: the weakness of nature which is wearied by the inflexibility of truth and plain statement and must be refreshed by an admixture of metaphors which depart somewhat from the truth. This gives the clue to the proper and legitimate use of metaphors; they are to be employed specifically, as musicians employ discordant sounds, to relieve the distaste of perfect harmony. But how frequently and at what point they should be introduced is a matter of considerable caution and skill. One warning will suffice for the present: that metaphors, hyperboles, and whatever varies from the plain and natural way of saying something should not be sought for their own sakes but as a kind of relief for nauseated nature. They are to be accepted on grounds of necessity, and consequently a good deal of moderation must be observed in their use. Thus Quintilian rightly says, "A sparing and opportune use of these figures gives lustre to speech; frequent use obscures and fills with disgust."[6] You will discover this fault often in many epigrams, especially in those of contemporary writers as I shall show by several examples later on. However, lest this doctrine should issue in too strict an austerity of diction, it should be noted that only those expressions are to be taken as metaphors that are remote from ordinary usage and offer the mind a double idea. Hence if a metaphor is so commonplace that it no longer has a figurative connotation and suggests nothing other than the notion itself for which it is used, then it should be numbered among proper rather than metaphorical expressions and does not fall in that class of tropes whose too frequent use is here censured. _On a too metaphorical style. Certain epigrams rejected for this reason._ Though poets are granted a greater indulgence in the use of tropes, nevertheless they have their own mean, or, as Cicero says, their own modesty, and there is ever an especial ornament to be derived from simplicity. Consequently those writers stray pretty far from beauty for whom, as it were, all nature plays the ham to the point that they say nothing in an ordinary way, imagine nothing in the way in which it is perceived outside of poems, but instead elevate, debase, alter, and clothe everything in a theatrical mask. For this reason we have excluded from this anthology a number of epigrams as too metaphorical: for example, these two by Daniel Heinsius, a man otherwise eminent in scholarship and letters:
