Leonardo’s judge and jury

A section of the Sistine Chapel fresco, Testament and Death of Moses.

Returning to the Sistine Chapel and the fresco of the Testament and Death of Moses attributed to Luca Signorelli and Bartolomeo Gatta…

I mentioned in a previous post that four of the multitude of figures depict Leonardo da Vinci. In this post I will present an explanation for one of them, the naked man seated on a tree stump and positioned centrally in the line of figures in the bottom half of the fresco.

Standing next to Leonardo is a figure wearing a bright blue jacket with most of his face hidden and his back to the viewer. Leonardo and the faceless man are presented in front of a group of men, some perhaps members of the Signoria, the government of Florence while others are members of the Medici family. With the exception of two, the group faces east toward another scene that shows Moses teaching the Law to the men, women and children gathered before him.

The group is taking the Law into account before passing judgement and possibly any sentence on Leonardo who had been anonymously reported for sodomy. His ‘anonymous’ accuser was another artist, Domenico Ghirlandaio, standing immediately behind Leonardo. Notice the snake-head shape of the fold above his right hand in the gold garment he is wearing. The snake reference not only points to Ghirlandaio as the sender of the anonymous letter to the Signoria, but also to the injury and the bruising on Leonardo’s right shoulder sustained from his attempt at human flight, hence the wing feature made of light silk attached around his neck. Was a tree or its stump the painful landing point?

Identifying Ghirlandaio is linked to the fresh-faced youth looking at the artist next to him. He is Giovanni di Lorenzo de’ Medici. The motif is borrowed from the fresco in the Sassetti Chapel in Florence depicting the Confirmation of the Rule of St Francis where both Giovanni and Piero are seen looking out directly at the artist who happens to be Ghirlandaio.

In the Moses fresco Piero (the Unfortunate) is the tall figure alongside Giovanni. Their father, Lorenzo the Magnificent, is to the right of the man in the blue jacket whose hand is raised as if appealing for help from Lorenzo. Could the man in blue be Leonardo Tornabuoini, one of the three other men charged with sodomy, and connected to the Medici family through Lorenzo’s mother Lucrezia Tornabuoni? This would explain why the face is hidden and possibly confirm the speculation that the charges against the men were dropped because of the Tornabuoni connection to the powerful Medici family.

The other figure not facing East but looking down on Leonardo is Antonio Pucci, Gonfaloniere of Justice and a close ally of the Medici family. His wealth and influence stemmed from the silk industry, hence the reference to the silk scarf or wing worn by Leonardo. The silk reference also connects to Ghirlandaio whose nickname means ‘garland maker’ and whose family produced silk scarves threaded with gold, a fashionable item with Florentine women of the time.

Pucci’s hands are explaining a point to Leonardo and his companion. He is squeezing his right thumb with the thumb and forfinger of his left hand. Could he be demonstrating a form of torture used by the authorities to punish or extract information, perhaps the application of thumbscrews or even amputation?

It’s a certainty that this fresco and, in particular, its central scene, was inspired by Sandro Botticelli’s Uffizi version of the Adoration of the Magi and its many reference to Leonardo including the episode relating to the charge of sodomy.

Luca Signorelli and/or Bartolomeo Gatta have replicated the right-hand corner of the Magi painting that shows Botticelli wrapped in a gold cloak standing behind the two figures representing Leonardo and one of his companions. But in the Moses fresco he is substituted by Ghirlandaio who, in the Magi painting is the ‘figure-head’ placed above Botticelli.

Ghirlandaio and Botticelli

Ghirlandaio’s blue-domed hat is not only a reference to his name Domenico but also to the prep work he did by painting the Sistine Chapel’s dome in blue with gold stars to represent the heavenly dome covering the world. Notice also the feather in his cap, a refrence to the quill Ghirlandaio used to write his ‘anonymous’ note to the Florentine authorities. The denunciation was posted in what was known as the ‘tamburo’ a drum-shaped box or barrel provided for reports on law-breaking.

From this we can understand why Botticelli has placed Ghirlandaio’s head above himself. Botticelli means ‘little barrel’ and so a reference to the ‘tamburo’ and further confirmation that it was Domenico who wrote the anonymous letter charging Leonardo and others with sodomy. His reason for denouncing Leonardo in this way? Botticelli provides some of the answers in another of his great works, The Calumny off Apelles.

Matching pairs… left, Leonardo da Vinci; right Orpheus, aka Leonardo, and Isabella d’Este

Another connection to Leonardo presented as the naked man in the Testament and Death of Moses fresco is Andrea Mantegna’s painting, Parnassus, completed about 1497 for Isabella d’Este and her studiolo. Mantegna’s Parnassus is heavly focused on Leonardo and his works. The figure of Orpheus playing his lyre is based on the figure of Leonardo in the Moses fresco and also linked to Botticelli’s Adoration of the Magi.

Finally, the bearded man, standing next to Lorenzo is the link between this scene and the one on the right featuring Moses teaching the law to the Hebrews.

The other bearded man seen tucked behind Ghirlandaio on the left side of the group has a legal status, and is a lawyer or notary. In a religious sense the scrolled brim on the front of his hat represents a phylactery or tefillin used to contain small scrolls inscribed with verses from the Torah. In a secular sense and as a notary licensed to witness signatures on documents the scrolled brim represents the box or ‘tamburo’ in which Ghirlandaio placed his written accusation against Leonardo. Here Signorelli confirms that the anonymous note was unsigned as witnessed by the notary standing next to Leonardo’s accuser.

A similar scroll motif is seen on one of the men in the next group to the left. He is Piero da Vinci, Leonardo’s father, and also a legal notary.

Leonardo’s ‘claw’… there’s more…

Last week, the world’s media reported on the diagnosis made by two Italian doctors which suggested Leonardo da Vinci suffered with ulnar palsy, or what is known as “claw hand”. The claim was first presented in the Journal of the Royal Society of Medicine on May 3, 2019, by Davide Lazzeri and Carlo Rossi.

That Leonardo was inflicted with a paralysis in his right hand is not unknown to historians. Antonio de Beatis, secretary to Cardinal Luigi d’Aragona, wrote in his travel diary about a visit to Leonardo in 1517. “One cannot indeed expect any more good work from him as a certain paralysis has crippled his right hand.”

Drs Davide Lazzeri and Carlo Rossi base their diagnosis on two portraits of Leonardo, a red-chalk drawing attributed to Giovanni Ambrogio Figino (1540-1608), and the other to an engraving made in 1505 by Marcantonio Raimondo (ca 1480-1527)

The engraving purports to show Leonardo playing a lira da braccio, suggesting therefore he may still had use of his right hand to enable to bow the instrument. The red-chalk drawing depicts Leonardo with his right hand cradled in the folds of his gown as if supporting an injured arm.

Historians generally attribute Leonardo’s paralysis to have manifested late in his life, but there is evidence to suggest the polymath bore his affliction even earlier and to the period he was living in Florence before moving to Milan in1482. The evidence is provided by three of his contemporaries, Andrea del Verriccio, Sandro Botticelli and Domenico Perugino. Even Leonardo himself produced work that hinted at his disability.

Dr Lazzeri suggests that an acute upper limb trauma, possibly from a fall, could have resulted in ulner palsy. He eplains, “The ulnar nerve runs from the shoulder to the little finger and manages almost all the hand muscles that allow fine motor movement.” Perhaps in the light of the this new analysis by Drs Lazzeri and Rossi, it can now be better understood just why Leonardo did not always complete his paintings or was at least slow to do so.

In 1479 a group of Florentine artists were commissioned to fresco the walls of the Sistine Chapel. It was considered a reconciliation initiative between Pope Sixtus IV and Lorenzo de’ Medici following the murder of Lorenzo’s brother Giuliano by conspirators supported by Sixtus. The four principal artists were Sandro Botticelli, Pietro Perugini, Domenico Ghirlandaio and Cosimo Rosselli. Surprisingly Leonardo da Vinci was not among the group. Could one of the reasons for his absence have been some kind of incapacity at the time, perhaps the result of an injury to his right arm?

In 1481, Leonardo was commissioned to paint an altarpiece depicting the Adoration of the Magi. It was never completed. Prior to that he started to paint St Jerome in the Wilderness. This work also remained unfinished and is now housed in the Vatican Museums.

Revisitng this work it is clear to see the emphasis placed on the suffering of St Jerome in the process of beating his breast with the rock held in his right hand. What is now particularly obvious in the light of last week’s report is the prominence and detail given to the right shoulder, the collar bone and afflicted expression on Jerome’s face. Outstretching his arm is seemingly a most painful process, enough to make him grimace and turn his head away. Could this be Leonardo recording the pain of his own injury in some way? Notice the claw-shaped grip around the stone held in the right hand.

Another painting that throws light on Leonardo’s claw-hand is Andrea de Verrocchio’s version of Tobias and the Angel (1470-65). For the angel Raphael read Verrocchio and for Tobias, Leonardo – the master instructing his apprentice. Close inspection of the linked arms clearly shows deformity in the young man’s right hand, particularly the little finger. Some art experts suggest Leonardo may have painted the fish that Tobias is carrying in his left hand.

Although Leonardo wasn’t part of the Florentine team sent to Rome to fresco the walls of the Sistine Chapel, he does feature in one of its paintings – The Trials of Moses – attributed to Botticelli. Leonardo is presented as the Egyptian being put to the sword by Moses and later buried. Both hands of the Egyptian, aka Leonardo, are formed as claws!

Returning to Florence in 1482 Botticelli went onto complete an earlier commission before he was called away to Rome, the Adoration of the Magi, the adaption now housed with Leonardo’s version in the Uffizi, Florence. The earlier mention of Leonardo being buried is alluded to again by Botticelli. The stone head to the left of the Holy Family group is Leonardo shown as the half buried Great Sphinx of Giza in Egypt. But this is not the only reference to Leonardo in the painting. In fact, there are are several, one of which points to the claw feature in Verrocchio’s Tobias and the Angel but is also given another meaning by Botticelli as part of one of several themes in the painting.

Adoration of the Magi, 1482, Sandro Botticelli, Uffizi, Florence

Leonardo is the figure wearing the pink cape crouching in front of Botticelli who is positioned in the right corner of the frame. The fingers of Leonardo’ right hand claw into the back of the hand of Giuliano de’ Medici. As to the reason for this, that’s another story.

Leonardo’s right hand is shown as clawing into the back Giuliano de’ Medici’s left hand.

Domenico Ghirlandaio, positioned next to Botticelli and wearing a feathered hat, was one of the artists who shared the workload in frescoing the walls of the Sistine Chapel. He also returned to Florence afterwards to complete a commisison he was given earlier to fresco the Sassetti Chapel in the Santa Trinita basilica. He produced five frescos on the life of St Francis. One of these, the last in the cycle, depicts the Death of St Francis seen surrounded by fellow friars and Florentine notables. The central figure hovering above the dead saint is meant to represent a knight named Jerome who doubted the authenticity and claims of the stigmata associated with Francis during his saintly life. When Francis died, Jerome examined the manifested wounds of Christ on the body of the holy man and was convinced they were genuine and so convereted his life.

A section of the fresco, Death of Francis, 1483-86, Domenico Ghirlandaio, Sassetti Chapel.

Here Ghirlandaio has borrowed the Leonardo/Egyptian figure from Botticelli’s Sistine Chapel fresco – note the similarity in hair colour and style, and the shade of the red and blue garments. Leonardo is known for dissecting dead bodies in his search for how the human body functions, and his notebooks are filled with drawing and sketches recording his findings. So here we have not only the connection back to Leonardo’s early painting of Jerome in the Wilderness, but also Ghirlandaio linking it to the knight known as Jerome who doubted the stigmata of Francis. Ghirlandaio also confirms Leonardo’s claw hand, not just by the shape of the right hand reaching into the body’s side wound, but also by the claw-shaped ‘praying hands’ of the two figures either side of Leonardo.

Leonardo held a skeptical view about some aspects Christianity, and was even considered a non-believer by some people. Ghirlandaio, it seems, was a believer in ‘miracles’ and in the use and power of relics to obtain physical healing. Perhaps this is why he presented Leonardo before the dead Francis in this final fresco, as an expression of his own personal faith and prayer made visible for others to witness. It is said that Leonardo renconciled with the Catholic Church when he was close to death and paid for Masses to be said for his soul’s salvation after he died.

The claim that Leonardo is represented in the engraving produced by Marcantonio Raimondo in 1505, has some merit. When he left Florence for Milan he brought with him a a silver lyre in the shape of a horse’s head as a gift for the Milanese ruler Ludovico Sforza. In Raimondo’s engraving Leonardo is depicted playing a ‘lira da braccio’ – an arm lyre – for the animals gathered around him. He is presented as Orpheus, “a legendary musician, poet, and prophet in ancient Greek religion and myth”, said to be able to charm all creatures with his music.

Parnnasus, 1497, Andrea Mantegna, Louvre, Paris

Leonardo portrayed as Orpheus may have been inspired by Andrea Mantegna’s famous painting Parnassus, now displayed in the Louvre. This is another work with several references to Leonardo and also Botticelli. In fact, it’s a parody on Botticelli’s Uffizi version of the Adoration of the Magi, which explains why Mantegna embedded the references to Leonardo. In the left corner of the painting is a young man seated on a tree trunk and playing a lyre for the dancing Maneads. The figure is Orpheus but also represents Giuliano de’ Medici. His left hand is claw-shaped to pluck the strings of the lyre. In Botticelli’s Uffizi Adoration Giuliano is also placed in the left corner, alongside a silver-head horse representing Leonardo’s lyre.

Orpheus, but also representing Giuliano Medici and possibly the young musician Atalante Migliorotti who accompanied Leonardo when he moved to Milan.

From these examples it can be seen that Leonardo’s claw-hand was not a late development in life, and that his contemporaries portayed his ailment in their paintings. There are probably more to come to light as the works I have cited are only those I have studied in recent months.

Cosimo, Sixtus, and now Jerome

St Jerome in the Wilderness, c 1480, Leonardo da Vinci, Vatican Museums

St Jerome in the Wilderness is another unfinished painting by Leonardo da Vinci. Believed to have been started sometime in 1480 before Leonardo moved from Florence to Milan, it’s now housed in the Vatican Museums.

At sometime in its history the panel was reduced in size. However, before it was cut down it served as inspiration for the upper half of Botticelli’s Uffizi Adoration of the Magi. It’s not hard to recognise that the kneeling Magi before the Infant Jesus is not only meant to resemble both Cosimo de’ Medici and Pope Sixtus IV as mentioned in previous posts, but also the figure of St Jerome depicted in Leonardo’s early work.

Other elements in Leonardo’s painting are also echoed and in a future post I will refer to these and the reason why Botticelli has made the connection to Jerome and placed the Saint – one of the early “Doctors of the Church” – in such a central position in his painting.

When Leonardo was ‘murdered’ by Moses (and Botticelli) in the Sistine Chapel

Today marks the 500th anniversary of the death of Leonardo da Vinci. The milestone is being acknowledged by special events around the world.

A little further back in time, 37 years to be precise and 1482, Sandro Botticelli recorded the death of Leonardo in a novel way – by portraying him in two roles, both as an Egyptian and a Hebrew slave in a fresco painting on a wall in the Sistine Chapel. The panel depicts the Trials of Moses and was one of several commissioned by Pope Sixtus IV using Botticelli and other Florentine artists.

A section of the Trials of Moses, Sandro Botticelli, 1482, Sistine Chapel.

The section shows Leonardo as the model for the Egyptian slain by Moses, as recorded in Exodus (2 : 11-14). Leonardo is also depicted as the bloodied Hebrew making an exit from captivity in Egypt but in danger of being enslaved by a woman seemingly set on protecting him. The woman is Florentina, the symbol of Florence.

Here Botticelli is referring to Leonardo’s brush with the law when he was one of a group of four men accused of sodomy. The charges were eventually dropped, some say because one of the other men was connected to the powerful Medici family. Had the law been applied in full then the four men could have faced execution. Guilty or innocent, the risk of execution was probably one of the reasons why Leonardo eventually left Florence and moved to Milan.

So here Botticelli expresses Leonardo’s fear of the severity of Florentine law, applied justly or unjustly, as portrayed by Moses who was chosen to present God’s law written in stone but which he had earlier applied unjustly on his own account by killing the Egyptian and hiding his body.

The passage from Exodus also relates what happened after Moses had killed the Egyptian. The following day he came across two Hebrews fighting each other. He said to the man who was in the wrong, “What do you mean by hitting your fellow countryman?” The man retorted, “And who appointed you to be prince over us and judge? Do you intend to kill me as you killed the Egyptian?”

Moses became frightened when he realised his crime had been discovered and fled to the land of Midian. Was Botticelli using this analogy to compare the flight of Moses to the flight of Leonardo to Milan, referring to the fact his “crime” was also uncovered?

Another narrative is that Leonardo was perhaps at odds with himself, battling with his sexuality and experiencing his nature to be in conflict with the law that threatened not only his existence but also his way of life, hence the reason why Botticelli depicted Leonardo as both of the Hebrew men.

The self-conflict motif can also be read into the fighting group of Moses and the Egyptian. In Botticelli’s Uffizi Adoration, Leonardo is painted in similar colours, green and yellow, to Moses in the Sistine Chapel frescos. But there are also other explanations for this match in the Adoration painting which I shall post on at another time.

The facial expression of the Hebrew on the ground is meant to relate to the screaming face of Leonardo that can be seen on the breastplate of Giuliano de’ Medici sculpted by Andrea del Verrocchio. The cuirass is hollowed as a protective piece of armour, similar to a shell. This is why Botticelli has shaped Leonardo’s cloak as a shell. Leonardo collected and made study draiwngs of shells. However, Botticelli is also suggesting that the vunerable point of any creature carrying a shell on its back and hiding underneath it, is its underside and belly region. This point is also made with a similar motif in the Uffizi Adoration painting.

There is another feature that links the face of Leonardo on the breastplate to his face portrayed on the Egyptian, and which connects with Moses. When the prophet came down from Mount Sinai for the second time “the skin on his face was radiant”. Artists generally show this as “horns of light” or what became known as the “horns of Moses”, usually depicted as two horns projecting from his head. They are meant to represent enlightenment or knowledge, as in knowing God’s law. In the fresco, Moses has yet to receive God’s law written on stone tablets.

However, the face of the Egyptian, aka Leonardo, has hair curled in the shape of horns. These are not only meant to represent the snakes associated with the image of the Gorgon Medusa and the pagan worship of the Egyptians of the time, but also suggest the brilliance of Leonardo, as gifted with knowledge and talents. The horns and the enlightened theme is also expressed on the breastpate, referring not only to Leonardo, but also the wearer Giuliano de’ Medici, considered a shining light and chivalrous knight of the Renaissance.

Heads of state

Seeing double… Cosimo de’ Medici and Pope Sixtus IV… adoring the Infant Saviour

In my previous post I pointed out that in Botticelli’s Uffizi version of the Adoration of the Magi, the figure of Joseph is leaning on a stone shelf which depicts Leonardo da Vinci as the head of the Great Sphinx. It wasn’t the first time Botticelli had portrayed Leonardo as the Sphinx. He had used the motif in an earlier work when he and other Florentine artists were commissioned by Pope Sixtus IV to fresco the walls of the Sistine Chapel. The commission was seen as a gesture of goodwill in building the peace process between Florence and the Pope in the aftermath of the Pazzi Conspiracy and assassination of Giuliano de’ Medci.

I also mentioned that the two tree trunks supporting the roof of the building housing the Holy Family represent the Roman numeral IV – four – and made the connection to the pharaoh Thutmose IV.

Now the numeral can also be understood as a pointer to Pope Sixtus IV, born Francesco della Rovere.

The two supports are from oak trees. Some oak leaves sprout from the vertical support even though it has been stripped of its bark at the base and so starved from nutrients and therefore any future life, a likely reference to the figure below of the hanged assassin Bernardo Bandini del Baroncelli, who served on the side of Sixtus in the pope’s efforts to remove the Medici family from its power base in Florence.

The Pope’s family name of Della Rovere means “of the oaks” or “the place of the oaks”. So here we see Botticelli expressing the Pope’s desire to take control of the Florentine Republic of which Lorenzo de’ Medici was the de facto ruler.

Art historians generally agree that the figure kneeling in front of the Infant Jesus is Lorenzo’s grandfather, Cosimo de’ Medici, but it also depicts Pope Sixtus IV as head of the Church on earth, and so a bridge (pontiff) between heaven and earth, a crossing into the promised land, not only led by Moses as described in the Old Testament, but also through the death and resurrection on the new-born Saviour, Jesus – hence the hands of Cosimo and Sixtus clasping the feet of the Infant. The two families, the Medici and the Della Rovere, are shown united in a symbolic sign of reconciliation and peace.

It was Pope Sixtus IV who built the Sistine Bridge across the Tiber in Rome. Notice the river-bend shape of the white scarf draped around his shoulders. Seen as Cosimo, the drape represents a waxing crescent moon.

There is another reference to ‘the place of oaks’ – the head of Sixtus – shaped as an acorn with its cup and nut. It’s gaunt appearance is reminiscent of some of the skull studies in Leonardo’s anatomical drawings and is meant to act as a ‘bridge’ to the sculpted head of Leonardo portrayed in the ‘rockface’ above. Which brings me back to the start of this post and the mention of Botticelli painting a similar motif in an earlier work.

For this we have to return again to the Sistine Chapel and the connection to Moses leading the Israelites to freedom from Egyptian captivity. The particular fresco is the Trials of Moses (or the Youth of Moses) painted on the southern wall.

My next post wil explain how and why Botticelli has linked references to Leonardo da Vinci in this fresco and the Uffizi Adoration.
