1501
Oil on wood, 50.2 × 34.6 cm
Private collection
It is undisputed that this painting is a work from Leonardo's workshop. The most important historical source in this context is the correspondence from spring 1501 between Pietro de' Nuvolari and Leonardo's admirer Isabella d'Este, Duchess of Mantua.
The Correspondence Between Isabella d'Este and Pietro de' Nuvolari
Isabella d'Este was eager to have her portrait painted by Leonardo and asked Pietro to keep her updated on his current projects. On April 3, 1501, he essentially reported that Leonardo was working on a large-scale sketch for the painting of the Virgin and Child with Saint Anne, but was mainly occupied with geometry, "to which all his striving belongs." Otherwise, he "did nothing, though two of his pupils made portraits, and in some cases he occasionally laid hands on them."
A few days later, on April 14, 1501, he wrote again, mentioning a small painting for Robertet, a favorite of the King of France, that was being worked on. He described it as follows: "The small painting he is currently working on is a Madonna sitting as if she wants to wind spindles; the boy places one foot in the basket with the spindles, he has grasped the reel and attentively observes its four spokes, which form a cross. And as he wishes for this cross, he laughs and holds it, for he does not want to give it to the mother, who, it seems, wants to take it from him."
Radiological studies have shown that the boy's right foot was indeed originally in a basket with spindles, as Pietro de' Nuvolari wrote, but this was later painted over.
From Leonardo's Workshop
Today, there is no doubt that the painting for Robertet depicts the present "Madonna of the Yarnwinder." However, there is some uncertainty about Leonardo's degree of involvement. As Pietro de' Nuvolari emphasized, Leonardo had little time for painting at that period due to his geometric studies, making it very likely that two of his pupils executed the portrait while Leonardo occasionally intervened.
This also explains why hardly any work attributed to Leonardo combines so many fragments from his unquestionably authentic paintings. Elements from the following works can be identified:
- Virgin of the Rocks (1483–86): the hand position is identical to that of the Virgin of the Rocks (mirrored and rotated about 45°), and the rocks in the right foreground resemble the foremost cliff of the Virgin of the Rocks
- Mona Lisa (1503–19): the bridge in the left background corresponds to that of the Mona Lisa
- Virgin and Child with Saint Anne (1502–19): the background landscape and the Madonna's head covering
- Saint John the Baptist (1513–19): the angle at which the Baptist's staff is inclined and rotated, as well as the child's arm position including the pointing finger
This is all the more remarkable since all the paintings except the Virgin of the Rocks were created after the Madonna of the Yarnwinder. Leonardo seems to have anticipated these elements here, which also indicates that he had a fundamental overall concept for his autograph works.
In addition to the version shown here, a second, less accomplished version (Buccleuch version) exists. Physical examinations have confirmed that both paintings were created simultaneously, as they exhibit the same later-painted corrections.
Together, the two Madonna of the Yarnwinder paintings now appear like a practice exercise by Leonardo for his two best pupils to copy him as accurately as possible. This aligns perfectly with Pietro de' Nuvolari's account, who wrote that Leonardo had no time for painting at that moment, "though two of his pupils make portraits, and in some cases he occasionally lays hands on them." The design likely comes from Leonardo, but aside from a few minor corrections, an autograph work by Leonardo is considered highly unlikely. The work is therefore usually described with the addition "from Leonardo's workshop."
