The century of Columbus

by James J. Walsh

It was after this, in his early manhood, that Leonardo became interested in the things of nature around him and made many investigations into their meaning. He took up astronomy for a time and anticipated some of the thoughts that Copernicus was to put in order in his great theory. Such ideas in astronomy were in the air at that time. Cardinal Nicholas of Cusa had more than hinted at them when, about the middle of the fifteenth century, he declared that the earth moved in the heavens like the other stars. Astronomical subjects were [{28}] favorite speculations for intellectual genius. Regiomontanus, who died before he was forty, was alive in Leonardo's boyhood, and after having begun that series of astronomical leaflets which later were to influence so deeply Columbus and the Portuguese navigators, was invited down to Rome to reform the calendar. Toscanelli made the observations on comets, out of which later their orbits were confirmed. Every form of natural observation caught the inquiring Leonardo's eye, and he studied the plants around him and meditated on crystal formation and occupied himself with all the forms of living things. Somehow his feeling seemed to be that such broadening of his intelligence would help him to breadth of expression in art, though probably it was only his native curiosity occupying itself in the insatiable youthful years with everything that came to hand. His achievements in science are sketched hurriedly in the chapter on Physical Science.

Leonardo seems to have occupied himself much with mechanical toys. He made mechanical birds that flew, mechanical lions that walked and a lizard which crawled and whose horns and eyes moved while the oscillating wings were constantly in motion. Every one of these contrivances, however, was the result of serious study. He took up with great assiduity the problem of flying and was quite sure that he would be able to make a machine by which men would accomplish locomotion through the air. He studied the wings of birds very carefully, and anticipated the knowledge of most of the principles of flight as they developed in later years. He used his mechanical lion as a bait to catch the attention of Francis I. The beast is said to have walked across the audience chamber towards the monarch until, when close to him, it stood up and disclosed the fact that the "Lily of France" was stamped upon its heart. Leonardo's own name is derived from lion and this was supposed to be his declaration of patriotic affection and loyalty to the French King.

Something of the busyness of his mind can be understood from the gossip that one hears about him in the letters of the time or even from what may be concluded from his own diary. It is said, for instance, that in the midst of the painting of the "Last Supper" there was quite an interruption in the work [{29}] because Leonardo became very much interested in the invention of a new machine for mincing meat and making sausages. The head of one of the Apostles was left unfinished for a time because Leonardo could not get the blades of the new machine fixed so as to make them more to his satisfaction. Unfriendly critics said that he would do anything so as to get away from his painting. Those who least understood declared that this was because he was trivial of mind and incapable of concentrating his attention. Anyone who has done artistic work of any kind, or indeed has devoted himself to literary work of any description, is likely to understand Leonardo's ways in such matters. The time comes when the particular vein of thought is exhausted for the moment and new ideas come slowly and with difficulty. The serious self-critical writer or artist recognizes that what he does at such times has not the significance he would like it to have and that he is likely to have to erase or greatly modify most of it afterwards or to regret it if he does not. If he is wise, then, he turns aside and gives his mind a complete rest by devoting it to something quite different from that in which he has been engaged before. If he insists on continuing his work after inspiration ceases or his particular vein of thought runs out, it becomes more and more difficult and more and more of a drudgery. Finally, unless he is almost entirely without proper self-appreciation, he literally has to give up the work that has become so difficult.

Leonardo did not wait for this, but after a certain set of ideas had run out devoted himself to other and quite different things. He had had trouble with cleaning his brushes, and had found that a rather strong lye could be extracted from fowls' droppings. He at once devoted considerable time to finding out whether the material thus obtained could not also be used for the washing of linen. Indeed, his attention to inventions for the relief of domestic difficulties stamps him as quite modern in his notions. Besides his sausage-making machine he invented a spit for the roasting of pigs and designed various forms of utensils that would be handier than those commonly in use at that time.

Some of Leonardo's expressions are well worth chronicling [{30}] because they show us so well the character of the man. He did not write any moral essays, but a number of expressions of his that have been preserved show that he had decided and very definite opinions with regard to many important human interests. His greatest picture was probably the "Battle of the Standards," in which, according to the descriptions preserved for us, he pictured all the horrors of war. He depicted the frenzy of contest at its fiercest. In one of his famous expressions he disposes of war in two words as pazzia bestialissima. I find it a little hard to translate that in the force of the original, but I suppose it would be something like "the climax of animal frenzy." Even that is not as strong as that superlative bestialissima in Italian.

The ease with which he transferred his services from one distinguished noble master to another has led some to suggest that he was lacking in loyalty, or at least was quite satisfied with life so long as he found someone to pay him for his work. As a matter of fact he often spent much more in experiments of various kinds than he was paid for the results of his labors, and money seems to have meant very little to him. He was known to be generous to his friends, and he once said "the poor are those who have many wants." He realized very well that poverty is entirely relative, and if a man is dissatisfied with what he has he is poor, no matter how much he has. As might be expected, above all Leonardo realized the preciousness of work. For him indeed blessed was the man who had found his work. His expression was "as a day well spent gives joyful sleep, so does a life well spent give joyful death."

With the disturbed conditions in Italy in his time he probably had to suffer many injustices, frequently had his labors interrupted, his work often undone, and it is easy to understand how much the jealousy of smaller men around him must have irritated him. He realized, however, that happiness depends on not permitting one's self to be bothered by such trifles. The only satisfaction is to go on with one's works. As he said, "The best shield against injustice is to double the cloak of longsuffering." His philosophy of life was in many ways ideal, then. Something of a stoic one needs must be to follow [{31}] it, but why should the petty trivialities of foolish human squabbling disturb a man who has all of art and science spread out before him and who knows so much more than others of his generation, but whose knowledge surely must have made it very clear to him how little after all he knew of all that was to be known?

Like his Italian contemporaries, generally, Leonardo remained faithful in his adhesion to the old Church. His charming "Madonna" and his "Last Supper" could scarcely have come from one who was not a believer. If these things were mere matters of imagination for the artists of the Renaissance, they would not have been expressed with such marvellous reality. We do not know much about his life, though we know so much about his work and thought. When he came to die, however, he left a legacy for masses for his soul. This was the custom of the time and might very well be considered only a conventional acknowledgment of his adhesion to the customs of his contemporaries. Besides, however, he left a sum of money for candles to be burnt at the shrine of the Blessed Virgin in the little village where he had been raised as a boy and where he had often prayed. This would seem to indicate that the faith of his childhood was still precious to him or had come back in its boyish tenderness at the end of his life. His whole career is that of a wonderfully-rounded man who could scarcely fail to recognize the place of the spiritual in life and its significance for man's understanding of the universe.

Burckhardt concludes one of the chapters of his work on "The Renaissance in Italy" with words that probably sum up better than any others Leonardo's character. No one was better fitted to know whereof he spoke than the great German historian of the Renaissance. "The colossal outlines of Leonardo's nature can never be more than dimly and distantly conceived."
