Read this excerpt from Charles Dickens's novel Great Expectations:
The most prominent object was a long table with a
tablecloth spread on it. ... An'épergne or centre-piece of
some kind was in the middle of this cloth; it was so heavily
overhung with cobwebs that its form was quite
undistinguishable
"What do you think that is?" she asked me, again
pointing with her stick; "that, where those cobwebs are?"..
"It's a great cake. A bride-cake. Mine!"
What does the cake most likely symbolize?
