Legion (demons)

Jesus healing the man from Gadara (Medieval illumination)

Legion means a large group or in another parlance it may mean "many". In the Christian Bible, it is used to refer to the group of demons, particularly those in two of three versions of the exorcism of the Gerasene demoniac, an account in the New Testament of an incident in which Jesus performs an exorcism. Legion is a large collection of demons that share a single mind and will.
