In the book The Scarlet Letter, does the scaffold have the same meaning in each scene?
Similar meanings. The scaffold in each scene is meant to symbolize declaring secrets. The first one, Hester doesn't say anything about her secret that she could so easily give up. The second and third obviously signify Dimmesdale wanting to tell. Also, the scaffold is a form of punishment. Dimmesdale doesn't feel like he's been punished for his sin and he needs to. Since the town punishes Hester by putting her on the scaffold to bear her shame in public, Dimmesdale thinks that's what he has to do to be free from his sin. I love that book. Hope you enjoy it. There's a lot of symbolism in it and it's great.
yes and no, When Hester stands on the scaffolding, its a forced punishment for committing adultery. and when Dimmesdale stands on it, it on his own because he feels guilty for doing this to Hester (giving her a child and her being shamed by the town)
Yes, the author is using frame technique, when the setting does not change but the characters do. During each of the successive scaffold scenes, new characters are present, showing the change in their relationships.
