I saw thee weep--the big bright tear <br />Came o'er that eye of blue; <br />And then methought it did appear <br />A violet dropping dew: <br />I saw thee smile--the sapphire's blaze <br />Beside thee ceased to shine; <br />It could not match the living rays <br />That filled that glance of thine. <br />As clouds from yonder sun receive <br />A deep and mellow dye, <br />Which scarce the shade of coming eve <br />Can banish from the sky, <br />Those smiles unto the moodiest mind <br />Their own pure joy impart; <br />Their sunshine leaves a glow behind <br />That lightens o'er the heart.<br /><br />George Gordon Byron<br /><br />http://www.poemhunter.com/poem/i-saw-thee-weep-2/
