Trafoi
One important ingredient in Freud's analysis was the North-Italian village Trafoi where he received the message of the suicide of one of his patients, struggling with sexual problems. Without Trafoi the substitute Boltraffio rhyming to it would be incomprehensible. Freud links Trafoi to the theme 'death and sexuality', a theme preceding the word finding problem in a conversation Freud had during a trip by train through Bosnia-Herzegowina.
The second important ingredient in Freud's analysis is the extraction of an Italian word signor from the forgotten name Signorelli. Herr, the German counterpart of Signor, is then linked to Herzegowina and the word Herr occurring, as Freud tells us, in the conversation.
Freud denies the relevance of the content of the frescos. Nevertheless psychoanalysts have pursued their investigations particularly into this direction, finding however no new explanation of the parapraxis. Jacques Lacan suggested that the parapraxis may be an act of self-forgetting.
