He then applied himself, but with greater care, to the anatomy of man, assisted by and in turn assisting, in this research, Messer Marc' Antonio della Torre, an excellent philosopher, who was then lecturing at Pavia, and who wrote of this matter; and he was one of the first (as I have heard tell) that began to illustrate the problems of medicine with the doctrine of Galen, and to throw true light on anatomy, which up to that time had been wrapped in the thick and gross darkness of ignorance. And in this he found marvellous aid in the brain, work, and hand of Leonardo, who made a book drawn in red chalk, and annotated with the pen, of the bodies that he dissected with his own hand, and drew with the greatest diligence; wherein he showed all the frame of the bones; and then added to them, in order, all the nerves, and covered them with muscles; the first attached to the bone, the second that hold the body firm, and the third that move it; and beside them, part by part, he wrote in letters of an ill-shaped character, which he made with the left hand, backwards; and whoever is not practised in reading them cannot understand them, since they are not to be read save with a mirror. Of these papers on the anatomy of man, a great part is in the hands of Messer Francesco da Melzo, a gentleman of Milan, who in the time of Leonardo was a very beautiful boy, and much beloved by him, and now is a no less beautiful and gentle old man; and he holds them dear, and keeps such papers together as if they were relics, in company with the portrait of Leonardo of happy memory; and to all who read these writings, it seems impossible that that divine spirit should have discoursed so well of art, and of the muscles, nerves, and veins, and with such diligence of everything. So, also, there are in the hands of ——,[11] a painter of Milan, certain writings of Leonardo, likewise in characters written with the left hand, backwards, which treat of painting, and of the methods of drawing and colouring. This man, not long ago, came to Florence to see me, wishing to print this work, and he took it to Rome, in order to put it into effect; but I do not know what may afterwards have become of it.

And to return to the works of Leonardo; there came to Milan, in his time, the King of France, wherefore Leonardo being asked to devise some bizarre thing, made a lion which walked several steps and then opened its breast, and showed it full of lilies.

In Milan he took for his assistant the Milanese Salai, who was most comely in grace and beauty, having fine locks, curling in ringlets, in which Leonardo greatly delighted; and he taught him many things of art; and certain works in Milan, which are said to be by Salai, were retouched by Leonardo.

He returned to Florence, where he found that the Servite Friars had entrusted to Filippino the painting of the panel for the high-altar of the Nunziata; whereupon Leonardo said that he would willingly have done such a work. Filippino, having heard this, like the amiable fellow that he was, retired from the undertaking; and the friars, to the end that Leonardo might paint it, took him into their house, meeting the expenses both of himself and of all his household; and thus he kept them in expectation for a long time, but never began anything. In the end, he made a cartoon containing a Madonna and a S. Anne, with a Christ, which not only caused all the craftsmen to marvel, but, when it was finished, men and women, young and old, continued for two days to flock for a sight of it to the room where it was, as if to a solemn festival, in order to gaze at the marvels of Leonardo, which caused all those people to be amazed; for in the face of that Madonna was seen whatever of the simple and the beautiful can by simplicity and beauty confer grace on a picture of the Mother of Christ, since he wished to show that modesty and that humility which are looked for in an image of the Virgin, supremely content with gladness at seeing the beauty of her Son, whom she was holding with tenderness in her lap, while with most chastened gaze she was looking down at S. John, as a little boy, who was playing with a lamb; not without a smile from S. Anne, who, overflowing with joy, was beholding her earthly progeny become divine—ideas truly worthy of the brain and genius of Leonardo. This cartoon, as will be told below, afterwards went to France. He made a portrait of Ginevra d' Amerigo Benci, a very beautiful work; and abandoned the work for the friars, who restored it to Filippino; but he, also, failed to finish it, having been overtaken by death.

Leonardo undertook to execute, for Francesco del Giocondo, the portrait of Monna Lisa, his wife; and after toiling over it for four years, he left it unfinished; and the work is now in the collection of King Francis of France, at Fontainebleau. In this head, whoever wished to see how closely art could imitate nature, was able to comprehend it with ease; for in it were counterfeited all the minutenesses that with subtlety are able to be painted, seeing that the eyes had that lustre and watery sheen which are always seen in life, and around them were all those rosy and pearly tints, as well as the lashes, which cannot be represented without the greatest subtlety. The eyebrows, through his having shown the manner in which the hairs spring from the flesh, here more close and here more scanty, and curve according to the pores of the skin, could not be more natural. The nose, with its beautiful nostrils, rosy and tender, appeared to be alive. The mouth, with its opening, and with its ends united by the red of the lips to the flesh-tints of the face, seemed, in truth, to be not colours but flesh. In the pit of the throat, if one gazed upon it intently, could be seen the beating of the pulse. And, indeed, it may be said that it was painted in such a manner as to make every valiant craftsman, be he who he may, tremble and lose heart. He made use, also, of this device: Monna Lisa being very beautiful, he always employed, while he was painting her portrait, persons to play or sing, and jesters, who might make her remain merry, in order to take away that melancholy which painters are often wont to give to the portraits that they paint. And in this work of Leonardo's there was a smile so pleasing, that it was a thing more divine than human to behold; and it was held to be something marvellous, since the reality was not more alive.

By reason, then, of the excellence of the works of this most divine craftsman, his fame had so increased that all persons who took delight in art—nay, the whole city of Florence—desired that he should leave them some memorial, and it was being proposed everywhere that he should be commissioned to execute some great and notable work, whereby the commonwealth might be honoured and adorned by the great genius, grace and judgment that were seen in the works of Leonardo. And it was decided between the Gonfalonier and the chief citizens, the Great Council Chamber having been newly built—the architecture of which had been contrived with the judgment and counsel of Giuliano da San Gallo, Simone Pollaiuolo, called Il Cronaca, Michelagnolo Buonarroti, and Baccio d' Agnolo, as will be related with more detail in the proper places—and having been finished in great haste, it was ordained by public decree that Leonardo should be given some beautiful work to paint; and so the said hall was allotted to him by Piero Soderini, then Gonfalonier of Justice. Whereupon Leonardo, determining to execute this work, began a cartoon in the Sala del Papa, an apartment in S. Maria Novella, representing the story of Niccolò Piccinino, Captain of Duke Filippo of Milan; wherein he designed a group of horsemen who were fighting for a standard, a work that was held to be very excellent and of great mastery, by reason of the marvellous ideas that he had in composing that battle; seeing that in it rage, fury, and revenge are perceived as much in the men as in the horses, among which two with the fore-legs interlocked are fighting no less fiercely with their teeth than those who are riding them do in fighting for that standard, which has been grasped by a soldier, who seeks by the strength of his shoulders, as he spurs his horse to flight, having turned his body backwards and seized the staff of the standard, to wrest it by force from the hands of four others, of whom two are defending it, each with one hand, and, raising their swords in the other, are trying to sever the staff; while an old soldier in a red cap, crying out, grips the staff with one hand, and, raising a scimitar with the other, furiously aims a blow in order to cut off both the hands of those who, gnashing their teeth in the struggle, are striving in attitudes of the utmost fierceness to defend their banner; besides which, on the ground, between the legs of the horses, there are two figures in foreshortening that are fighting together, and the one on the ground has over him a soldier who has raised his arm as high as possible, that thus with greater force he may plunge a dagger into his throat, in order to end his life; while the other, struggling with his legs and arms, is doing what he can to escape death.

It is not possible to describe the invention that Leonardo showed in the garments of the soldiers, all varied by him in different ways, and likewise in the helmet-crests and other ornaments; not to mention the incredible mastery that he displayed in the forms and lineaments of the horses, which Leonardo, with their fiery spirit, muscles, and shapely beauty, drew better than any other master. It is said that, in order to draw that cartoon, he made a most ingenious stage, which was raised by contracting it and lowered by expanding. And conceiving the wish to colour on the wall in oils, he made a composition of so gross an admixture, to act as a binder on the wall, that, going on to paint in the said hall, it began to peel off in such a manner that in a short time he abandoned it, seeing it spoiling.
