What paper did 91 people sign in the crucible?

In Arthur Miller's play "The Crucible," the document that 91 people signed is known as the "confession." During the Salem witch trials in the 17th century, many individuals were pressured into admitting to practicing witchcraft under false pretenses by signing such confessions. These confessions ultimately played a crucial role in condemning those individuals and contributing to the hysteria surrounding the witch trials.
