Our feeling that the smile of Monna Lisa del Gioconda awakened in the man the memory of the mother of his first years of childhood would thus be confirmed from another work of Leonardo. Following the production of Monna Lisa, Italian artists depicted in Madonnas and prominent ladies the humble dipping of the head and the peculiar blissful smile of the poor peasant girl Caterina, who brought to the world the noble son who was destined to paint, investigate, and suffer. When Leonardo succeeded in reproducing in the face of Monna Lisa the double sense comprised in this smile, namely, the promise of unlimited tenderness, and sinister threat (in the words of Pater), he remained true even in this to the content of his earliest reminiscence. For the love of the mother became his destiny, it determined his fate and the privations which were in store for him. The impetuosity of the caressing to which the vulture phantasy points was only too natural. The poor forsaken mother had to give vent through mother's love to all her memories of love enjoyed as well as to all her yearnings for more affection; she was forced to it, not only in order to compensate herself for not having a husband, but also the child for not having a father who wanted to love it. In the manner of all ungratified mothers she thus took her little son in place of her husband, and robbed him of a part of his virility by the too early maturing of his eroticism. The love of the mother for the suckling whom she nourishes and cares for is something far deeper reaching than her later affection for the growing child. It is of the nature of a fully gratified love affair, which fulfills not only all the psychic wishes but also all physical needs, and when it represents one of the forms of happiness attainable by man it is due, in no little measure, to the possibility of gratifying without reproach also wish feelings which were long repressed and designated as perverse.[63] Even in the happiest recent marriage the father feels that his child, especially the little boy has become his rival, and this gives origin to an antagonism against the favorite one which is deeply rooted in the unconscious.
