AGAMEMNON. Princes, What grief hath set these jaundies o’er your cheeks? The ample proposition that hope makes In all designs begun on earth below Fails in the promis’d largeness; checks and disasters Grow in the veins of actions highest rear’d, As knots, by the conflux of meeting sap, Infects the sound pine, and diverts his grain Tortive and errant from his course of growth. Nor, princes, is it matter new to us That we come short of our suppose so far That after seven years’ siege yet Troy walls stand; Sith every action that hath gone before, Whereof we have record, trial did draw Bias and thwart, not answering the aim, And that unbodied figure of the thought That gave’t surmised shape. Why then, you princes, Do you with cheeks abash’d behold our works And call them shames, which are, indeed, naught else But the protractive trials of great Jove To find persistive constancy in men; The fineness of which metal is not found In fortune’s love? For then the bold and coward, The wise and fool, the artist and unread, The hard and soft, seem all affin’d and kin. But in the wind and tempest of her frown Distinction, with a broad and powerful fan, Puffing at all, winnows the light away; And what hath mass or matter by itself Lies rich in virtue and unmingled.
