Here's how Dickens uses the spilled wine:
* Symbol of Oppression and Inequality: The wine represents the blood and labor of the French peasantry, which is literally being spilled by the callous nobility. The wine is intended for the privileged, yet it is wasted and trampled by the very people it is meant to sustain.
* The Spark of Revolution: The spilled wine serves as a catalyst for the French Revolution. The people, already angered by their poverty and oppression, see the waste of the wine as a final insult, fueling their rage and igniting the uprising.
* Blood and Sacrifice: The spilled wine foreshadows the blood that will be shed in the revolution. It serves as a visceral reminder of the human cost of the rebellion, both for the revolutionaries and the aristocracy.
* The Cycle of Violence: The spilled wine symbolizes the cycle of violence that perpetuates the revolution. Just as the spilled wine creates chaos and bloodshed, the revolution itself becomes a destructive force, consuming its own people.
In short, the spilled wine is more than just a physical event; it's a powerful symbol that embodies the themes of oppression, inequality, revolution, and the cycle of violence that drive the narrative of *A Tale of Two Cities*.
