Herzfeld surely must have had something similar in mind when stating that in Monna Lisa Leonardo encountered himself and therefore found it possible to put so much of his own nature into the picture, "whose features from time immemorial have been imbedded with mysterious sympathy in Leonardo's soul."[56] Let us endeavor to clear up these intimations. It was quite possible that Leonardo was fascinated by the smile of Monna Lisa, because it had awakened something in him which had slumbered in his soul for a long time, in all probability an old memory. This memory was of sufficient importance to stick to him once it had been aroused; he was forced continually to provide it with new expression. The assurance of Pater that we can see an image like that of Monna Lisa defining itself from Leonardo's childhood on the fabric of his dreams, seems worthy of belief and deserves to be taken literally. Vasari mentions as Leonardo's first artistic endeavors, "heads of women who laugh."[57] The passage, which is beyond suspicion, as it is not meant to prove anything, reads more precisely as follows:[58] "He formed in his youth some laughing feminine heads out of lime, which have been reproduced in plaster, and some heads of children, which were as beautiful as if modeled by the hands of a master...." Thus we discover that his practice of art began with the representation of two kinds of objects, which would perforce remind us of the two kinds of sexual objects which we have inferred from the analysis of his vulture phantasy. If the beautiful children's heads were reproductions of his own childish person, then the laughing women were nothing else but reproductions of Caterina, his mother, and we are beginning to have an inkling of the possibility that his mother possessed that mysterious smile which he lost, and which fascinated him so much when he found it again in the Florentine lady.[59] [Illustration: SAINT ANNE]
