GODot

Waiting for Godot by Samuel Beckett is a play full of surprises. At first it was very weird: the main characters were very hard to decipher, even in a physical way, and the tone and content of the conversations between them were very strange. Then, when Pozzo came with Lucky, the contrast between Lucky's master and the two main characters made it easier to draw some conclusions about Vladimir and Estragon. 

To me, the role of an invisible character such as Godot is only important as background knowledge, because even though he is constantly mentioned by the other actors, he doesn't ever appear on stage and doesn't affect the interaction between the characters in the book. Godot is just the reason Vladimir and Estragon are there and the reason they encounter Pozzo and the boy, but he doesn't influence what they say and how they act with others. They just wait for Godot and don't move because of him, but he doesn't play a part in how they act. If I would have to guess, considering the time and place this play was written, I interpret the character of Godot as the new idea of God and religion that people were starting to have at the time. As faith started to decrease, people believed less and less in an omnipotent being that was watching their every move. So, as Vladimir and Estragon in the play, they know God is there, but they don't let Him influence their actions.
