Leonardo’s and Schreber’s clinical cases are important Freudian studies both written in 1910. The two clinical cases study mainly homosexuality, but they also constitute indirect analysis: the first one about a Renaissance scientist through the biographies and his pictorial work; the second one about a delusional person through his memoirs. Besides, they have activated in Freud an identification process with his subject of study. The similarities between autobiographical experiences can leads to the hypothesis that the formulation of a theory of mental functioning, which is the secondary object of the two cases, can be derived from the self-analysis that Freud performed about a dozen years earlier, and therefore there may be an affinity between the Freudian self-analysis’ writing process and Leonardo and Schreber’s creative processes.
