of Abigail that changes her mind; Mary knows she could easily be accused of witchcraft also. She has seen how easily innocent people have been targeted, the tables turning on them in court. Ultimately, in order to protect herself and avoid more scrutiny and a possible accusation, she recants her deposition.

The perfect place for such a monologue would be at the end of act 3 or in act 4—after Mary has been able to see the impact of her decision and possibly reflect on how important it was to remain honest. She could speak about how she lacked the courage necessary to do the right thing and also mention the courage she has seen displayed in other people who have been wrongly accused. She could admit she feels terrible guilt and remorse. If she speaks in act 4, it could be after it is revealed that Abigail has escaped, and Mary realizes how selfish Abigail's behavior was.

An interesting character that you could write a monologue for would be Giles Corey. Giles is depicted as an ornery old man, who makes the terrible mistake of questioning his wife's behavior in front of Reverend Hale at the beginning of the play. Giles initially has suspicions about the books his wife is reading but is astonished to learn that Martha has been arrested and accused of witchcraft. In act 3, Giles Corey gets thrown out of court after insisting that Thomas Putnam is using the witch trials to buy land. Giles Corey proceeds to inform Deputy Governor Danforth that a reliable citizen overheard Thomas Putnam telling his daughter to accuse George Jacobs of witchcraft in order to buy his land. Thomas Putnam knows that George will openly confess to witchcraft in order to save his life, and his land will soon be available for purchase. Whenever Danforth requests the name of the man who overheard Thomas Putnam, Giles refuses to tell him and is arrested for contempt of court.

In act 4, Elizabeth Proctor tells John that Giles died an honorable death by refusing to confess to witchcraft. Unfortunately, the audience hears of Giles's valiant death secondhand via Elizabeth's description. An interesting monologue could be written at the beginning of act 4 and depict Giles's final thoughts before being pressed to death. You could describe Giles's feelings of regret for expressing his concern about his wife, which resulted in her arrest, or his feelings about the corrupt court. Giles could also elaborate on why he refuses to offer a false confession or speak about how he wishes to die an honorable death, which would be similar to John Proctor's final words. You could also describe Giles's concerns for Martha, Rebecca, John, and his sons.

There are many characters that you could choose and create an interesting monologue for.  My recommendation is to write a monologue for Abigail.  I would place the monologue in Act 4.  

In Act 4, the audience is told that Abigail has run away and stolen money from Parris.  

Parris: Excellency, I think they be aboard a ship. Danforth stands agape. My daughter tells me how she heard them speaking of ships last week, and tonight I discover my--my strongbox is broke into.

I would have the monologue take place before Abigail escapes.  Have her debating with herself whether or not she should leave.  There's a lot that you could explore there.  A part of her would have to want to stay.  She's in love with John Proctor, and guaranteed she is thinking about a way to save his life and still have him for herself without Elizabeth.  She might even fantasize about having John run away with her.  You could have Abigail speak in an angry rant for a bit about how much she despises Elizabeth.  End the monologue with Abigail realizing that her name is completely ruined in Salem, and the only "logical" plan is to steal some money and run away.  

One way to write an effective monologue based off of a character in The Crucibleis to choose a complex character and explore the depth of their experience.

One complex character is Abigail.  She plays such an important role in the drama's development.  She is the reason why the trials reach such a fevered pitch.  She initiated many of the accusations and stirred the emotionally contagious pot that Salem became.  However, she simply disappears at drama's end.  We really have no idea what has become of her.  It might be very interesting to write about Abigail's life once she leaves Salem.  A monologue that talks about what she experienced, whether she still thinks of Salem and John Proctor, or even what she hoped to gain out of leaving Salem could be very effective.  It would delve into the thoughts and motivations of one of the drama's most important characters.

Another topic for an emotionally intense monologue would be Giles Corey.  He occupied such an important role in Act III.  His legal challenge to Danforth and Hathorne was significant to the drama.  He is hauled off to jail and the only information we have about him comes from Elizabeth when she talks about his death.  It might be unique to get into his mind while he is in jail. He knows that he will refuse to speak.  Exploring the motivations behind his silence might be very persuasive.  The monologue could even take place as he is sentenced.  It could examine his thoughts as the stones are added upon him.  There could be a delving into the physical pain he experiences as well as his emotional resolve to continue with it.  His cry of "More weight" is synonymous with resistance in the face of intense pressure.  Entering into this mindset might be very worthwhile in monologue form.

You can select any character from Miller's drama for an effective monologue. The idea would be to enter their mind and explore what they might have felt and experienced as a result of the emotionally draining witch trials. 

If you are writing a monologue for Tituba, a character in Arthur Miller's play The Crucible, one of the most influential aspects of your monologue will be where you decide to place the monologue within the play:

• As a prequel to Act One: Tituba, at the request of several of the village girls, performs a "ceremony" for them, although little detail exists about what this ceremony is. You could explain how Tituba feels about the request, explain what happens during the ceremony, or explain how Tituba is feeling after the ceremony is discovered by Reverend Parris. 
• Concluding Act One: Tituba has admitted to witchcraft and accused other women -- does she feel guilty? Is it true? Is she afraid? 
• Within Act Two: Tituba is stuck in prison, seeing people come in and out as they are accused of witchcraft and found guilty. Does she feel like she caused this? Does she feel like a victim? 
• Within Act Three: Tituba is due to hang in Act III. How does she feel? 

Good luck!
