Quote:
Then thou, our fancy of itself bereaving,13
Dost make us marble with too much conceiving,
here our imagination of this works( shakespear's works ) is bereaved of real conception
because of the magic of his work that we cannot write as it
also, he make us marble >> refer to brightness and immortality by his work
Line 13, again, has a funny word order so bereaving refers to "fancy." In other words, the line would mean "you, bereaving (taking away) our fancy (imagination) from itself," in other words Shakespeare is supplying such wonderful fancy that the readers' own imagination is beside itself with amazement. Just as you say, or imagination is bereaved of it's own fancy because his work is so magical. Line 14, you seem to get the idea. The important thing you don't note is that this is the place where the reader is turned into "marble" because of too much "conceiving" (this can mean either "understanding" or "experience of emotion"). Not only does the reader's understanding of Shakespeare's works amaze him/her so much that they are as imobile as stone. This is an important point because it is here that the reader is turned into marble so that the reader becomes the marble monument like the one described in the first few lines.
