Background: Bridget Cleary was brutally burned to death by her husband in the presence of her father and several close relatives in rural Ireland in 1895. The story has attracted public attention for more than a century now, for numerous reasons.
Aims: The issue of psychiatric illness in this tragedy, and the role of fairy mythology in belief systems in 19th Century rural Ireland are reviewed, particularly in relation to providing explanations for physical and psychiatric illness, along with learning disability.
Methods: Reference was made to a wide range of sources featuring the burning of Bridget Cleary.
Results: There is some evidence to suggest that the actions of Michael Cleary and other key protagonists were influenced by Capgras syndrome and folie a plusiers.
Conclusions: Delusional belief in fairy mythology may have coloured the psychological make-up, motivations and behaviour of some of the people involved in the killing of Bridget Cleary.
