What is a good thesis statement on symbolism in Elie Wiesel's Night?

“Night,” by Elie Wiesel, is a novel of young Wiesel’s survival in the concentration camps during WWII.

There are several symbols in the novel.  One of the main symbols is the night itself.  Wiesel uses night to symbolize the darkness of the history of the Jewish people during this time.  It also symbolizes Elie’s loss of his faith in God.  Another symbol is fire.  There are many places in the novel where fire is mentioned and a good example of this is when they arrive at Auschwitz.  “A young Pole who was in charge welcomed us to Auschwitz, “The same smoke hovers over all our heads.” 

Another example is when they are first taken into custody and don’t really understand what is happening.  A more experienced Jewish man says, “Over there.  Do you see the chimney over there?  Do you see it?  And the flames, do you see them? (Yes, we saw the flames).  Over there, that is where they will take you. You will be burned; burned to cinders.”

As a thesis you might compare the symbols of night and fire and how they directly affect each other throughout the novel.
