Barnabas the Barmy was a wizard who made a foolish attempt to train trolls for the ballet. A moving tapestry depicting his attempt hung on the seventh floor of Hogwarts School of Witchcraft and Wizardry, opposite the entrance to the Room of Requirement.
- "Barnabas" is a Greek form of an Aramaic name. In Acts in the New Testament the byname Barnabas was given to a man named Joseph, a companion of Paul on his missionary journeys. The original Aramaic is unattested, but it may be from בּר נביא (bar naviya') meaning "son of the prophet", though in Acts 4:36 it is claimed that the name means "son of encouragement". As an English name, it came into occasional use after the 12th century.
- According to the Oxford Dictionary of English, the word "barmy" is an informal adjective, chiefly used in Britain that means mad, crazy or extremely foolish.
