The Crucible by Arthur Miller is a play based on the actual events that, in 1692, led to the Salem Witch Trials, a series of hearings before local magistrates to prosecute over 150 people accused of witchcraft in colonial Massachusetts between February 1692 and May 1693.
The play begins with Reverend Parris praying over his daughter Betty who lies unconscious in her bed. Through conversations between Parris and his niece Abigail Williams, and between several girls, the audience learns that the girls, including Abigail and Betty, were engaged in occultist activities in a nearby forest. These, apparently, were led by Tituba, Parris's slave from Barbados. On catching them in the act, Parris jumped from a bush, startling them. Betty promptly fainted and has not yet recovered. During this session, Abigail also drank chicken blood in a bid to kill Elizabeth Proctor. She tells the girls that she will murder anyone who utters a word about what happened. The townspeople do not know exactly what the girls were up to, but there are rumors of witchcraft.
