Incubus. Sinistrari tells of a case which came under his own notice when a deacon, a monk of the Certosa at Pavia, was sorely vexed by an Incubus. Exorcisms seemed unavailing; the Incubus himself in the shape of Father Prior blessed the place with Holy Water. However, the demon was at last banished. See my translation, Demoniality, pp. 57-59, and passim.
