These three heraldic shields have deteriorated drastically and are difficult to read, not least because they were painted over in about 1700, partially rediscovered seventy-five years later, and then fully uncovered only in the middle of the nineteenth century. However, the shield in the upper left—in all likelihood the first thing painted by Leonardo—is clearly that of Lodovico’s eldest son, Massimiliano. The name of the boy, who was born in January 1493, reflected Lodovico’s shifting allegiances and expanding political ambitions. He was originally named Ercole in honor of his maternal grandfather, Ercole d’Este of Ferrara, but within the year Lodovico had him rechristened Massimiliano to ingratiate himself with the emperor Maximilian. Since the boy bore the title duke of Pavia, his coat of arms showed both the Visconti viper and the eagles of Pavia.
Massimiliano’s younger brother, Francesco, named for his paternal grandfather, was born almost exactly two years later, in February 1495, at
around the time Leonardo was beginning work in the refectory. The newborn was celebrated on the shield in the upper right-hand corner of the room. The heraldic imagery is almost entirely lost, but the words DVX BARI—that is, duke of Bari, young Francesco’s title—are still legible. Lodovico and his wife were commemorated in the center, in the largest of the three lunettes. Once again, the heraldic imagery is difficult to read, although both the imperial eagle and the Visconti viper are present, while Beatrice would have been represented by the white eagle and the fleur-de-lis that adorned the Este family crest.
Leonardo enjoyed inventing mottoes and clever
imprese
, but producing these three heraldic shields would have been an unimaginative task. He enlivened the images by surrounding each with a wreath of palm fronds adorned with grasses, acorns, and oak leaves, and fruit such as apples, apricots, and pears. In the central lunette he even added blackberries, olives, and quinces. These details he painted with naturalistic precision (even the veins in the leaves of the pear branches are carefully painted) despite the fact that they are over thirty feet from the floor and would have been difficult if not impossible to see in the dim light of the refectory. He also added gold detailing to the coats of arms, creating the illusion, through a sense of depth, that actual shields were suspended high on the wall.
The three heraldic shields were not the only ones that Leonardo planned for the refectory. Lodovico, who thought so often of his ancestors, was also thinking about his posterity, and of how the refectory of Santa Maria delle Grazie could be turned into a kind of Sforza family gallery. To that end, Leonardo added two more shields in the lunettes on the walls adjacent to where he was about to paint his
Last Supper
. These were left blank, awaiting the birth of further Sforza heirs.

The gesture was an optimistic one at a time when the House of Sforza faced such dangerous threats. One thing must have occurred to Leonardo as he began work: should Lodovico fall from power, the commission was certain to be canceled.

displaying the Sforza coat of arms
Leonardo painted the Sforza coats of arms with the help of an underdrawing. He scored the wall with a stylus, creating an outline (possibly with the help of a cartoon) that he proceeded to reinforce with charcoal. The freehand charcoal sketch reveals backward hatching: a sure sign that Leonardo himself drew it. However, in time-honored workshop fashion, he almost certainly delegated some of the painting to various of his assistants.
Whether working on panels or frescoes, artists always assigned the lesser tasks, such as background scenery and repetitive details, to their assistants or apprentices. Michelangelo’s famous claim that he worked alone on the vault of the Sistine Chapel, “without any help whatever, not even someone to grind his colours for him,” is demonstrably untrue.

Patrons accepted that not every inch of a fresco could be painted by the hand of the master, but their contracts usually stressed that the head of the workshop should be responsible for the most important, conspicuous, and difficult aspects. Luca Signorelli’s 1499 contract for frescoes in Orvieto Cathedral was typical in its insistence that Signorelli himself was to paint “the faces and all parts of the figures from the middle of each figure upwards.”
44
The contract also specified that Signorelli was to mix his pigments himself, an indication of the difficulty and importance of this tedious and time-consuming task.
The precise identity of Leonardo’s assistants is not known for certain, apart from Salai. The little terror was by now fifteen and working as Leonardo’s faithful if undistinguished helper. Gathered about Leonardo in Milan, however, were more talented assistants, a small group of young
painters who formed a kind of School of Leonardo. They included a wealthy young Milanese nobleman, born about 1467, named Giovanni Antonio Boltraffio. Another of Leonardo’s pupils, also born around 1467, was Marco d’Oggiono. Each had suffered the occupational hazard of working with Leonardo: Salai stole silverpoint drawings from both of them.
Boltraffio and Oggiono had struck out on their own by the mid-1490s, working together in Milan on an altarpiece for the newly built oratory attached to San Giovanni sul Muro. They absorbed their master’s style so thoroughly that at one time this altarpiece was attributed to Leonardo himself. Leonardo had a close working relationship with both men, to the point of providing drawings and designs for them to work with (as perhaps was the case with their altarpiece for the oratory). He could easily have called upon them for assistance with his mural. No document records their presence in his workshop at this time, but absence of evidence is not necessarily evidence of their absence.
The notebooks do record the presence of other assistants. Ever the dutiful accountant, Leonardo registered numerous payments to various members of his household and studio in the Corte dell’Arengo: Gian Pietro, Benedetto, Giovanni, Gian Maria, Bartolomeo, and Gherardo.
45
Gian Pietro was probably Giovanni Pietro Rizzoli, later known as Giampietrino, a young Milanese painter who is known to have worked in Leonardo’s studio.
46
The identities of the others are unclear. Recorded in Leonardo’s laconic accounting and spare of other details, their names are not easily identifiable as painters. It is unlikely that all were involved in the execution of the mural. However, several of them, such as Benedetto and Giovanni, were clearly skilled craftsmen of some sort, able to earn a sizeable income in the space of a few short months. If they were experienced frescoists, they must have regarded Leonardo’s plans for the refectory with incredulity and amazement.
CHAPTER 8
“Trouble from This Side and That”
Charles VIII and his troops reached the safety of the fortress at Asti in the middle of July 1495. They were ragged, exhausted, and ill provisioned, having been reduced to drinking stagnant water from ditches and eating nothing but bread—“and that none of the best”—following their flight from Fornovo.
1
Ten months earlier, Asti had been the setting for Charles’s first meeting with Lodovico Sforza. On that occasion, Charles was entertained by Lodovico with singers, dancers, and musicians, while Beatrice astonished the flower of French chivalry with the beauty of her gown, whose bodice (according to one breathless French report) “was loaded with diamonds, pearls and rubies, both in front and behind.”
2
But now the two princes were at war, with Charles awaiting the arrival of twenty thousand Swiss mercenaries so he could renew his assault.
Lodovico could at least take heart that his rival for the lordship of Milan, the duke of Orléans, was faring badly. Having been forced to retreat into Novara following his bold feint at Milan, Louis and his troops were
now besieged, surrounded by a combined force of Venetian and Milanese soldiers. Lodovico did not plan to attack Novara. He lacked the artillery, and in any case he had no wish to see one of his own cities destroyed by cannon. Instead, he decided to starve Louis and his troops, who had fled inside Novara in such a panic that, in a drastic oversight, they failed to provision themselves. The Holy League’s soldiers diverted the water that powered the mills inside the town, leaving the French troops unable to grind their small store of grain. The soldiers were starved of information as well as food, since Lodovico, ever the master of deception, sent into Novara forged documents claiming that Charles had died in the field at Fornovo. Morale inside the walls was not helped by another rumor: that Charles was too busy trying to seduce Anna Solaro, the daughter of a local lord, to trouble himself with their plight.

The siege of Novara lasted through the summer of 1495 and into the autumn. The town quickly plunged into the most dire misery. “Every day some were starved to death,” wrote a French chronicler.
4
From Asti, Charles dispatched a train of pack animals in hopes of provisioning the town, but it was easily captured and the supplies confiscated.
At length, there was hope for the besieged troops. With both winter and the Swiss mercenaries fast approaching, Francesco Gonzaga began to make overtures to Charles, first of all returning the sword and helmet captured at Fornovo, along with the album of the king’s amorous conquests. Charles expressed his thanks and, through his ambassador to Venice, let it be known that he, too, desired peace. Negotiations were opened, with Lodovico initially taking a hard line. But he needed peace much more than he wanted war, and the evacuation of Novara was quickly agreed. By the time the siege ended, after three months and fourteen days, two thousand of Louis’s troops had perished of starvation and disease. A French ambassador was shocked by the sight of the survivors—“so lean and meagre that they looked more like dead than living people; and truly, I believe never men endured more misery.”
5
Hundreds more died on the roadsides as they evacuated Novara, and a dozen miles away, at the French outpost of Vercelli, the dung heaps were stacked with corpses.
Louis was eager for revenge against Lodovico. Immediately after the evacuation, according to a shocked French ambassador, he “began to talk of fighting again.”
6
As the twenty thousand Swiss mercenaries finally arrived
in the French camp, he urged Charles to cease negotiations and turn his army loose on Milan.
These political events may have temporarily distracted Leonardo from his work in Santa Maria delle Grazie. No situation was so dire that Lodovico could not see fit to summon a bit of pomp and circumstance, and once more Leonardo—“the arbiter of all questions relating to beauty and elegance”—may have been enrolled into service.
