Christoph Haizmann, a seventeenth-century Bavarian painter, suffered from
abnormal religious experiences. Our study considers whether Haizmann’s
case fits the model of schizophrenia through the concept of
‘bizarreness’. Haizmann’s words and actions were
discordant and bizarre even within the religious framework of the seventeenth century.
We propose that ‘bizarreness’ is an expression of relative
deviation from the social and cultural norms of a particular epoch and that
‘bizarreness’ may be an important concept as an indicator of
schizophrenia. In this sense, Haizmann was likely to have suffered from
schizophrenia. Haizmann’s case may offer a good example for the
investigation of schizophrenia in history through the concept of
‘bizarreness’, an approach that can indicate deviation from
ordinariness and commonness even in religious models.
