The Crucible by Arthur Miller is about the Salem Witch Trials of 1692 in Massachusetts. Nineteen men and women and two dogs were hanged after being convicted of witchcraft. The play is an allegory for McCarthyism in 1950s America. A crucible is a place of extreme heat and severe test, and the play examines what happens when authority is challenged and hysteria takes hold. The play is still relevant as an allegory today when societies seek perfection at the cost of individual freedoms.
