Edmund Spenser - Sonnet 9 from Amoretti lyrics

Long while I sought to what I might compare Those powerful eyes, which lighten my dark spright Yet I find I naught on earth to which I dare Resemble the image of their goodly light. Not to the sun: for they do shine by night; Nor to the moon: for they are changed never; Nor to the stars: for they have purer sight; Nor to the fire: for they consume not ever; Nor to the lightning: for they still persever; Nor to the diamond: for they are more tender; Nor unto crystal: for naught may them sever; Nor unto gla**: such baseness might offend her; Then to the maker self they likest be, Whose light doth ligthen all that here we see.
