Definition of Metaphor
As Darnay embarks on his ill-fated journey to France, he can feel himself becoming increasingly trapped as he draws closer to Paris. Dickens uses metaphor to evoke Darnay’s sense of imprisonment:
Not a mean village closed upon him, not a common barrier dropped across the road behind him, but he knew it to be another iron door in the series that was barred between him and England. The universal watchfulness so encompassed him, that if he had been taken in a net, or were being forwarded to his destination in a cage, he could not have felt his freedom more completely gone.
Dickens uses the metaphor of the grindstone to comment on the workings of history:
Unlock with LitCharts A+The great grindstone, Earth, had turned when Mr Lorry looked out again, and the sun was red on the court-yard. But, the lesser grindstone stood alone there in the calm morning air, with a red upon it that the sun had never given, and would never take away.
