It may be that you for your part will regard the warning with which I close as an exaggeration. I shall only venture on an indirect picture of my conviction by telling you an old story and leaving you to make what use you like of it. German literature is familiar with a little town called Schilda, to whose inhabitants clever tricks of every possible sort are attributed. The citizens of Schilda, so we are told, possessed a horse with whose feats of strength they were highly pleased and against which they had only one objection - that it consumed such a large quantity of expensive oats. They determined to break it of this bad habit very gently by reducing its ration by a few stalks every day, till they had accustomed it to complete abstinence. For a time things went excellently: the horse was weaned to the point of eating only one stalk a day, and on the succeeding day it was at length to work without any oats at all. On the morning of that day the spiteful animal was found dead; and the citizens of Schilda could not make out what it had died of.

 

We should be inclined to think that the horse was starved and that no work at all could be expected of an animal without a certain modicum of oats.

 

I must thank you for your invitation and for the attention with which you have listened to me.0


LEONARDO DA VINCI AND A MEMORY OF HIS CHILDHOOD (1910)

 

 

When psychiatric research, normally content to draw on frailer men for its material, approaches one who is among the greatest of the human race, it is not doing so for the reasons so frequently ascribed to it by laymen. ‘To blacken the radiant and drag the sublime into the dust’ is no part of its purpose, and there is no satisfaction for it in narrowing the gulf which separates the perfection of the great from the inadequacy of the objects that are its usual concern. But it cannot help finding worthy of understanding everything that can be recognized in those illustrious models, and it believes there is no one so great as to be disgraced by being subject to the laws which govern both normal and pathological activity with equal cogency.

 

Leonardo da Vinci (1452-1519) was admired even by his contemporaries as one of the greatest men of the Italian renaissance; yet in their time he had already begun to seem an enigma, just as he does to us to-day. He was a universal genius ‘whose outlines can only be surmised, - never defined’.¹ In his own time his most decisive influence was in painting, and it was left to us to recognize the greatness of the natural scientist (and engineer) that was combined in him with the artist. Though he left behind him masterpieces of painting, while his scientific discoveries remained unpublished and unused, the investigator in him never in the course of his development left the artist entirely free, but often made severe encroachments on him and perhaps in the end suppressed him. In the last hour of his life, according to the words that Vasari gives him, he reproached himself with having offended God and man by his failure to do his duty in his art.² And even if this story of Vasari’s has neither external nor much internal probability but belongs to the legend which began to be woven around the mysterious Master even before his death, it is still of incontestable value as evidence of what men believed at the time.

 

¹ The words are Jacob Burckhardt’s, quoted by Konstantinowa (1907).

² ‘Egli per reverenza, rizzatosi a sedere sul letto, contando il mal suo e gli accidenti di quello, mostrava tuttavia quanto avea offeso Dio e gli uomini del mondo, non avendo operato nell’ arte come si conveniva.’ [‘He having raised himself out of reverence so as to sit on the bed, and giving an account of his illness and its circumstances, yet showed how much he had offended God and mankind in not having worked at his art as he should have done.’] Vasari.

 

What was it that prevented Leonardo’s personality from being understood by his contemporaries? The cause of this was certainly not the versatility of his talents and the range of his knowledge, which enabled him to introduce himself to the court of the Duke of Milan, Lodovico Sforza, called Il Moro, as a performer on a kind of lute of his own invention, or allowed him to write the remarkable letter to the same duke in which he boasted of his achievements as architect and military engineer. For the days of the renaissance were quite familiar with such a combination of wide and diverse abilities in a single individual - though we must allow that Leonardo himself was one of the most brilliant examples of this. Nor did he belong to the type of genius who has received a niggardly outward endowment from nature, and who in his turn places no value on the outward forms of life, but in a spirit of painful gloom flies from all dealings with mankind. On the contrary, he was tall and well proportioned; his features were of consummate beauty and his physical strength unusual; he was charming in his manner, supremely eloquent, and cheerful and amiable to everyone. He loved beauty in the things that surrounded him; he was fond of magnificent clothing and valued every refinement of living. In a passage from the treatise on painting, which reveals his lively capacity for enjoyment, he compares painting with its sister arts and describes the hardships that await the sculptor: ‘For his face is smeared and dusted all over with marble powder so that he looks like a baker, and he is completely covered with little chips of marble, so that it seems as if his back had been snowed on; and his house is full of splinters of stone and dust. In the case of the painter it is quite different... for the painter sits in front of his work in perfect comfort. He is well-dressed and handles the lightest of brushes which he dips in pleasant colours. He wears the clothes he likes; and his house is full of delightful paintings, and is spotlessly clean. He is often accompanied by music or by men who read from a variety of beautiful works, and he can listen to these with great pleasure and without the din of hammers and other noises.’¹

 

¹ Trattato della Pittura.4

 

It is indeed quite possible that the idea of a radiantly happy and pleasure-loving Leonardo is only applicable to the first and longer period of the artist’s life. Afterwards, when the downfall of Lodovico Moro’s rule forced him to leave Milan, the city that was the centre of his activity and where his position was assured, and to pursue a life lacking in security and not rich in external successes, until he found his last asylum in France, the sparkle of his temperament may have grown dim and some strange sides of his nature may have been thrown into prominence. Moreover the turning of his interests from his art to science, which increased as time went on, must have played its part in widening the gulf between himself and his contemporaries. All the efforts in which in their opinion he frittered away his time when he could have been industriously painting to order and becoming rich (as, for example, his former fellow-student Perugino did) seemed to them to be merely capricious trifling or even caused him to be suspected of being in the service of the ‘black art’. We are in a position to understand him better, for we know from his notes what were the arts that he practised. In an age which was beginning to replace the authority of the Church by that of antiquity and which was not yet familiar with any form of research not based on presuppositions, Leonardo - the forerunner and by no means unworthy rival of Bacon and Copernicus - was necessarily isolated. In his dissection of the dead bodies of horses and human beings, in his construction of flying machines, and in his studies on the nutrition of plants and their reactions to poisons, he certainly departed widely from the commentators on Aristotle, and came close to the despised alchemists, in whose laboratories experimental research had found some refuge at least in those unfavourable times.

 

The effect that this had on his painting was that he took up his brush with reluctance, painted less and less, left what he had begun for the most part unfinished and cared little about the ultimate fate of his works. And this was what he was blamed for by his contemporaries: to them his attitude towards his art remained a riddle.

Several of Leonardo’s later admirers have made attempts to acquit his character of the flaw of instability. In his defence they claim that he is blamed for what is a general feature of great artists: even the energetic Michelangelo, a man entirely given up to his labours, left many of his works incomplete, and it was no more his fault than it was Leonardo’s in the parallel instance. Moreover, in the case of some of the pictures, they urge, it is not so much a question of their being unfinished as of his declaring them to be so. What appears to the layman as a masterpiece is never for the creator of the work of art more than an unsatisfactory embodiment of what he intended; he has some dim notion of a perfection, whose likeness time and again he despairs of reproducing. Least of all, they claim, is it right to make the artist responsible for the ultimate fate of his works.

 

Valid as some of these excuses may be, they still do not cover the whole state of affairs that confronts us in Leonardo. The same distressing struggle with a work, the final flight from it and the indifference to its future fate may recur in many other artists, but there is no doubt that this behaviour is shown in Leonardo in an extreme degree. Solmi (1910, 12) quotes the remark of one of his pupils: ‘Pareva che ad ogni ora tremasse, quando si poneva a dipingere, e però non diede mai fine ad alcuna cosa cominciata, considerando la grandezza dell’arte, tal che egli scorgeva errori in quelle cose, che ad altri parevano miracoli.’¹ His last pictures, he goes on, the Leda, the Madonna di Sant’ Onofrio, Bacchus, and the young St. John the Baptist, remained unfinished ‘come quasi intervenne di tutte le cose sue...’² Lomazzo, who made a copy of the Last Supper, refers in a sonnet to Leonardo’s notorious inability to finish his works:

 

Protogen che il pennel di sue pitture

Non levava, agguaglio il Vinci Divo

Di cui opra non è finita pure.³

 

¹ [‘He appeared to tremble the whole time when he set himself to paint, and yet he never completed any work he had begun, having so high a regard for the greatness of art that he discovered faults in things that to others seemed miracles.’]

² [‘As happened more or less to all his works.’]

³ [‘Protogenes, who never lifted his brush from his work, was the equal of the divine Vinci, who never finished anything at all.’] Quoted by Scognamiglio (1900).

 

The slowness with which Leonardo worked was proverbial. He painted at the Last Supper in the Convent of Santa Maria delle Grazie in Milan, after the most thorough preparatory studies, for three whole years. One of his contemporaries, Matteo Bandelli, the story-writer, who at the time was a young monk in the convent, tells how Leonardo often used to climb up the scaffolding early in the morning and remain there till twilight never once laying his brush aside, and with no thought of eating or drinking. Then days would pass without his putting his hand to it. Sometimes he would remain for hours in front of the painting, merely examining it in his mind. At other times he would come straight to the convent from the court in the castle at Milan, where he was making the model of the equestrian statue for Francesco Sforza, in order to add a few strokes of the brush to a figure, and then immediately break off.¹ According to Vasari he spent four years in painting the portrait of Mona Lisa, the wife of the Florentine Francesco del Giocondo, without being able to bring it to final completion. This circumstance may also account for the fact that the picture was never delivered to the man who commissioned it, but instead remained with Leonardo and was taken to France by him.² It was bought by King Francis I, and to-day forms one of the greatest treasures of the Louvre.

 

If these reports of the way in which Leonardo worked are compared with the evidence of the extraordinarily numerous sketches and studies which he left behind him and which exhibit every motif appearing in his paintings in a great variety of forms, we are bound totally to reject the idea that traits of hastiness and unsteadiness acquired the slightest influence over Leonardo’s relation to his art. On the contrary, it is possible to observe a quite extraordinary profundity, a wealth of possibilities between which a decision can only be reached with hesitation, demands which can hardly be satisfied, and an inhibition in the actual execution which is not in fact to be explained even by the artist inevitably falling short of his ideal. The slowness which had all along been conspicuous in Leonardo’s work is seen to be a symptom of this inhibition and to be the forerunner of his subsequent withdrawal from painting.³ It was this too which determined the fate of the Last Supper - a fate that was not undeserved. Leonardo could not become reconciled to fresco painting, which demands rapid work while the ground is still moist, and this was the reason why he chose oil colours, the drying of which permitted him to protract the completion of the painting to suit his mood and leisure. These pigments however detached themselves from the ground on which they were applied and which separated them from the wall. Added to this, the defects in the wall, and the later fortunes of the building itself, determined what seems to be the inevitable ruin of the picture.4

³ Pater: ‘But it is certain that at one period of his life he had almost ceased to be an artist.’

4 See von Seidlitz (1909, 1) for the history of the attempts to restore and preserve the picture.7

 

The miscarriage of a similar technical experiment appears to have caused the destruction of the Battle of Anghiari, the painting which, in competition with Michelangelo, he began to paint some time afterwards on a wall of the Sala del Consiglio in Florence, and which he also abandoned in an unfinished condition. Here it seems as if an alien interest - in experimentation - at first reinforced the artistic one, only to damage the work later on.

The character of Leonardo the man showed some other unusual traits and apparent contradictions. A certain inactivity and indifference seemed obvious in him. At a time when everyone was trying to gain the widest scope for his activity - a goal unattainable without the development of energetic aggressiveness towards other people - Leonardo was notable for his quiet peaceableness and his avoidance of all antagonism and controversy. He was gentle and kindly to everyone; he declined, it is said, to eat meat, since he did not think it justifiable to deprive animals of their lives; and he took particular pleasure in buying birds in the market and setting them free.¹ He condemned war and bloodshed and described man as not so much the king of the animal world but rather the worst of the wild beasts.² But this feminine delicacy of feeling did not deter him from accompanying condemned criminals on their way to execution in order to study their features distorted by fear and to sketch them in his notebook. Nor did it stop him from devising the cruellest offensive weapons and from entering the service of Cesare Borgia as chief military engineer. He often gave the appearance of being indifferent to good and evil, or he insisted on measurement by a special standard. He accompanied Cesare in a position of authority during the campaign that brought the Romagna into the possession of that most ruthless and faithless of adversaries. There is not a line in Leonardo’s notebooks which reveals any criticism of the events of those days, or any concern in them. A comparison suggests itself here with Goethe during the French campaign.

If a biographical study is really intended to arrive at an understanding of its hero’s mental life it must not - as happens in the majority of biographies as a result of discretion or prudishness - silently pass over its subject’s sexual activity or sexual individuality. What is known of Leonardo in this respect is little: but that little is full of significance. In an age which saw a struggle between sensuality without restraint and gloomy asceticism, Leonardo represented the cool repudiation of sexuality - a thing that would scarcely be expected of an artist and a portrayer of feminine beauty. Solmi quotes the following sentence of his which is evidence of his frigidity: ‘The act of procreation and everything connected with it is so disgusting that mankind would soon die out if it were not an old-established custom and if there were not pretty faces and sensuous natures.’¹ His posthumous writings, which not only deal with the greatest scientific problems but also contain trivialities that strike us as scarcely worthy of so great a mind (an allegorical natural history, animal fables, jokes, prophecies),² are chaste - one might say even abstinent - to a degree that would cause surprise in a work of belles lettres even to-day. So resolutely do they shun everything sexual that it would seem as if Eros alone, the preserver of all living things, was not worthy material for the investigator in his pursuit of knowledge.³ It is well known how frequently great artists take pleasure in giving vent to their phantasies in erotic and even crudely obscene pictures. In Leonardo’s case on the contrary we have only some anatomical sketches of the internal female genitals, the position of the embryo in the womb and so on.4

 

¹ Solmi (1908).

² Herzfeld (1906).

³ An exception to this (though an unimportant one) is perhaps to be found in his collected witticisms - belle facezie - which have not been translated. See Herzfeld (1906, 151).

4 [Footnote added 1919:] Some remarkable errors are visible in a drawing made by Leonardo of the sexual act seen in anatomical sagittal section, which certainly cannot be called obscene. They were discovered by Reitler (1917) and discussed by him in the light of the account which I have given here of Leonardo’s character:

 

‘It is precisely in the process of portraying the act of procreation that this excessive instinct for research has totally failed - obviously only as a result of his even greater sexual repression. The man’s body is drawn in full, the woman’s only in part. If the drawing reproduced in Fig. 1 is shown to an unprejudiced onlooker with the head visible but all the lower parts covered up, it may be safely assumed that the head will be taken to be a woman’s. The wavy locks on the forehead, and the others, which flow down the back approximately to the fourth or fifth dorsal vertebra, mark the head as more of a woman’s than a man’s.

 

‘The woman’s breast reveals two defects. The first indeed is an artistic one, for its outline gives it the appearance of a breast that is flabby and hangs down unpleasingly. The second defect is anatomical, for Leonardo the researcher had obviously been prevented by his fending off of sexuality from ever making a close examination of a nursing woman’s nipples. Had he done so he would have been bound to notice that the milk flows out of a number of separate excretory ducts. Leonardo, however, drew only a single duct extending far down into the abdominal cavity and probably in his view drawing the milk from the cisterna chyli and perhaps also connected in some way with the sex organs. It must of course be taken into consideration that the study of the internal organs of the human body was at that time made extremely difficult, since the dissection of bodies was regarded as desecration of the dead and was most severely punished. Whether Leonardo, who had certainly only very little material for dissection at his disposal, knew anything at all of the existence of a lymph-reservoir in the abdominal cavity is therefore in fact highly questionable, although in his drawing he included a cavity that is no doubt intended to be something of the sort. But from his making the lactiferous duct extend still further downwards till it reaches the internal sex organs we may suspect that he was trying to represent the synchronization of the beginning of the secretion of milk and the end of pregnancy by means of visible anatomical connections as well. However, even if we are ready to excuse the artist’s defective knowledge of anatomy by referring it to the circumstances of his time, the striking fact still remains that it is precisely the female genital that Leonardo has treated so carelessly. The vagina and something that looks like the portio uteri can no doubt be made out, but the lines indicating the uterus itself are completely confused.

 

Fig. 1

 

‘The male genital on the other hand is depicted by Leonardo much more correctly. Thus, for instance, he was not satisfied with drawing the testis but also put in the epididymis, which he drew with perfect accuracy.

‘What is especially remarkable is the posture in which Leonardo makes coitus take place. Pictures and drawings by famous artists exist which depict coitus a tergo, a latere, etc., but when it comes to a drawing of the sexual act being performed standing up, we must surely suppose that there was a sexual repression of quite special strength to have caused it to be represented in this isolated and almost grotesque way. If one wants to enjoy oneself it is usual to make oneself as comfortable as possible: this of course is true for both the primal instincts, hunger and love. Most of the peoples of antiquity took their meals in a lying position and it is normal in coitus to-day to lie down just as comfortably as did our ancestors. Lying down implies more or less a wish to stay in the desired situation for some time.

 

‘Moreover the features of the man with the feminine head are marked by a resistance that is positively indignant. His brows are wrinkled and his gaze is directed sideways with an expression of repugnance. The lips are pressed together and their corners are then drawn down. In this face can be seen neither the pleasure of love’s blessings nor the happiness of indulgence: it expresses only indignation and aversion.

‘The clumsiest blunder, however, was made by Leonardo in drawing the two lower extremities. The man’s foot should in point of fact have been his right one; for since Leonardo depicted the act of union in an anatomical sagittal section it follows of course that the man’s left foot would be above the plane of the picture. Conversely, and for the same reason, the woman’s foot should have belonged to her left side. But in fact Leonardo has interchanged male and female. The male figure has a left foot and the female one a right foot. This interchange is easiest to grasp if one recalls that the big toes lie on the inner sides of the feet.

 

‘This anatomical drawing alone would have made it possible to deduce the repression of libido - a repression which threw the great artist and investigator into something approaching confusion.’

[Added 1923:] These remarks of Reitler’s have been criticized, it is true, on the ground that such serious conclusions should not be drawn from a hasty sketch, and that it is not even certain whether the different parts of the drawing really belong together.9

 

It is doubtful whether Leonardo ever embraced a woman in passion; nor is it known that he had any intimate mental relationship with a woman, such as Michelangelo’s with Vittoria Colonna. While he was still an apprentice, living in the house of his master Verrocchio, a charge of forbidden homosexual practices was brought against him, along with some other young people, which ended in his acquittal. He seems to have fallen under this suspicion because he had employed a boy of bad reputation as a model.¹ When he had become a Master, he surrounded himself with handsome boys and youths whom he took as pupils. The last of these pupils, Francesco Melzi, accompanied him to France, remained with him up to his death and was named by him as his heir. Without sharing in the certainty of his modern biographers, who naturally reject the possibility that there was a sexual relationship between him and his pupils as a baseless insult to the great man, we may take it as much more probable that Leonardo’s affectionate relations with the young men who - as was the custom with pupils at that time - shared his existence did not extend to sexual activity. Moreover a high degree of sexual activity is not to be attributed to him.

 

¹ According to Scognamiglio (1900, 49) there is a reference to this episode in an obscure and even variously read passage in the Codex Atlanticus: ‘Quando io feci Domeneddio putto voi mi metteste in prigione, ora s’io lo fo grande, voi mi farete peggio.’ [‘When I represented the Lord God as a baby, you put me in prison; now if I represent him as an adult you will do worse to me. ‘]0

 

There is only one way in which the peculiarity of this emotional and sexual life can be understood in connection with Leonardo’s double nature as an artist and as a scientific investigator. Among his biographers, to whom a psychological approach is often very alien, there is to my knowledge only one, Edmondo Solmi, who has approached the solution of the problem; but a writer who has chosen Leonardo as the hero of a great historical novel, Dmitry Sergeyevich Merezhkovsky, has made a similar reading of this unusual man the basis of his portrait and has given clear expression to his conception, not indeed in plain language, but (after the way of writers of imagination) in plastic terms.¹ Solmi’s verdict on Leonardo is as follows (1908, 46): ‘But his insatiable desire to understand everything around him, and to fathom in a spirit of cold superiority the deepest secret of all that is perfect, had condemned Leonardo’s work to remain for ever unfinished.’

In an essay in the Conferenze Fiorentine the following pronouncement of Leonardo’s is quoted, which represents his confession of faith and provides the key to his nature: ‘Nessuna cosa si può amare nè odiare, se prima non si ha cognition di quella.’² That is to say: One has no right to love or hate anything if one has not acquired a thorough knowledge of its nature. And the same is repeated by Leonardo in a passage in the treatise on painting where he seems to be defending himself against the charge of irreligion: ‘But such carping critics would do better to keep silent. For that (line of conduct) is the way to become acquainted with the Creator of so many wonderful things, and this is the way to love so great an Inventor. For in truth great love springs from great knowledge of the beloved object, and if you know it but little you will be able to love it only a little or not at all...’³

² Bottazzi (1910, 193).

³ Trattato della Pittura.1

 

The value of these remarks of Leonardo’s is not to be looked for in their conveying an important psychological fact; for what they assert is obviously false, and Leonardo must have known thus as well as we do. It is not true that human beings delay loving or hating until they have studied and become familiar with the nature of the object to which these affects apply. On the contrary they love impulsively, from emotional motives which have nothing to do with knowledge, and whose operation is at most weakened by reflection and consideration. Leonardo, then, could only have meant that the love practised by human beings was not of the proper and unobjectionable kind: one should love in such a way as to hold back the affect, subject it to the process of reflection and only let it take its course when it has stood up to the test of thought. And at the same time we understand that he wishes to tell us that it happens so in his case and that it would be worth while for everyone else to treat love and hatred as he does.

 

And in his case it really seems to have been so. His affects were controlled and subjected to the instinct for research; he did not love and hate, but asked himself about the origin and significance of what he was to love or hate. Thus he was bound at first to appear indifferent to good and evil, beauty and ugliness. During this work of investigation love and hate threw off their positive or negative signs and were both alike transformed into intellectual interest. In reality Leonardo was not devoid of passion; he did not lack the divine spark which is directly or indirectly the driving force - il primo motore - behind all human activity. He had merely converted his passion into a thirst for knowledge; he then applied himself to investigation with the persistence, constancy and penetration which is derived from passion, and at the climax of intellectual labour, when knowledge had been won, he allowed the long restrained affect to break loose and to flow away freely, as a stream of water drawn from a river is allowed to flow away when its work is done. When, at the climax of a discovery, he could survey a large portion of the whole nexus, he was overcome by emotion, and in ecstatic language praised the splendour of the part of creation that he had studied, or - in religious phraseology - the greatness of his Creator. This process of transformation in Leonardo has been rightly understood by Solmi. After quoting a passage of this sort in which Leonardo celebrates the sublime law of nature (‘O mirabile necessità...’), he writes (1910, 11) ‘Tale trasfigurazione della scienza della natura in emozione, quasi direi, religiosa, è uno dei tratti caratteristici de’ manoscritti vinciani, e si trova cento e cento volte espressa...’¹
