of Leonardo's precocious sexual investigation, which in our opinion became decisive for his entire life.
A brief reflection now admonishes us that we should not be satisfied with the explanation of the vulture-tail in Leonardo's childhood phantasy. It seems as if it contained more than we as yet understand. For its more striking feature really consisted in the fact that the nursing at the mother's breast was transformed into being nursed, that is into a passive act which thus gives the situation an undoubted homosexual character. Mindful of the historical probability that Leonardo behaved in life as a homosexual in feeling, the question obtrudes itself whether this phantasy does not point to a causal connection between Leonardo's childhood relations to his mother and the later manifest, if only ideal, homosexuality. We would not venture to draw such conclusion from Leonardo's disfigured reminiscence were it not for the fact that we know from our psychoanalytic investigation of homosexual patients that such a relation exists, indeed it really is an intimate and necessary relation.
