A severed head. The mouth is open in a scream that has not yet finished. The eyes are wide and turned downward toward the body that is no longer there. The hair is alive with green serpents that lift and uncoil in the moment of the head's separation from the neck. Blood, dark and abundant, falls from the cut in a slow ribbon. The face is caught at the half-second between life and death — neither one nor the other, frozen in the exact moment of becoming.
This is Medusa, painted by the twenty-six-year-old Caravaggio in 1597 in Rome. It is painted on a convex wooden shield, about fifty-five centimetres across, prepared with canvas glued onto the front of the wood and then painted in oil. It is one of the most disquieting small paintings in European art, and one of the very few in which a painter signs his own face into the centre of the violence.
The commission, the shield, and the Cardinal who paid for it
In 1597 Caravaggio was working for Cardinal Francesco Maria del Monte in Rome. Del Monte was the cardinal of Tuscany at the papal court and the agent in Rome for the Medici grand dukes in Florence. He housed Caravaggio in his palace, fed him, gave him pigments and canvases, and in exchange received the early Caravaggios that we now think of as the painter's first masterpieces — the Bacchus, the Lute Player, the Fortune Teller, and this Medusa.
The Medusa shield was painted as a diplomatic gift. Del Monte sent it to his patron Grand Duke Ferdinand I de' Medici in Florence, to be added to the Medici armoury. The Medici had been collecting ceremonial parade shields painted with classical mythological subjects for over a century; the Medusa was a traditional shield subject (it appears on the shield of Athena in classical mythology, and on the breastplate of every Renaissance equestrian portrait of a prince or general). What Caravaggio added was the realism. Earlier painted Medusa shields had been heraldic — stylised heads with snakes drawn like ornaments. Caravaggio painted the moment of decapitation.
The shield is convex, curving outward toward the viewer. This is a problem for the painter, because the painted face would normally bulge forward unconvincingly. Caravaggio solved the problem by painting the Medusa as if seen in a concave mirror — the bulge of the shield becomes, in the picture, the curve of a mirror's reflection. The head appears slightly recessed into the surface, even though the surface itself rises outward. The painter has not painted the head; he has painted the reflection of the head as it would appear at the moment Perseus saw it in his polished shield.
The Perseus story Caravaggio is painting
In the Greek myth, Perseus is sent by an enemy king to bring back the head of Medusa, the Gorgon whose face turns living beings to stone. Perseus cannot look at her directly. He approaches her cave at night while she sleeps, looking at her only in the reflection of his polished bronze shield, and decapitates her with a single stroke of the sword that the gods have given him. He then escapes with the head, which he uses several times in the rest of the myth as a weapon — anyone who looks on the severed face turns to stone.
Caravaggio's Medusa is the head at the exact moment after the stroke. The scream is still open. The eyes have not yet stilled. The serpents in the hair are still alive. Caravaggio paints what the head looks like in Perseus's shield — the head seen in the reflective surface that Perseus is holding. The painting is, in this reading, the shield itself: we are Perseus, looking down at our own shield, seeing the Medusa's reflection. The painting puts the viewer in Perseus's place.
Caravaggio painted the moment of beheading twice. The Medusa shield in 1597 is the first; the Judith Beheading Holofernes painted two years later (and now in the same Roman collection where it has spent four hundred years) is the second. In the Judith picture Caravaggio paints not a mythological head but a real one — a man, lying on a bed, being sawn through the neck by a young woman in a white shirt. The two pictures are companion pieces in the painter's own development. The Medusa is the first time Caravaggio paints a face caught in the half-second between life and death; the Judith is the moment he stops painting myth and starts painting humans.
The face in the shield is Caravaggio's own
Look at the Medusa face carefully. The features are not female. The jaw is square. The brow is heavy. The mouth is large and the upper lip is thin. The eyes, despite their terror, are clearly the eyes of a male model. This is a face that art historians identified at the beginning of the twentieth century, by comparison with the Caravaggio self-portraits painted in other contemporary works — the Sick Bacchus of 1593, the Bacchus of 1596, the head of the young David in the David with the Head of Goliath painted twelve years later. The Medusa, the screaming severed Gorgon on the Cardinal's diplomatic shield, is Caravaggio himself.
Why did Caravaggio sign his own face into a Medusa? The most common reading is that the painter was making a joke about the medium of painting itself. The Medusa turns those who look at her to stone; the painted Medusa turns those who look at her into nothing — the viewer becomes a participant in the myth at the cost of their own gaze. Caravaggio is, in the painting, the petrifying force: the painter who can stop you in your tracks. The self-portrait is a small intellectual move dressed up as a piece of mythological terror.
There is a second reading. Caravaggio was a violent man. He had been arrested for fighting in the street several times by 1597. He would, in 1606, kill a man in a sword duel and flee Rome with a death sentence on his head. The Medusa is, in this reading, a confession or a self-knowledge — the painter recognising the violence in his own face. Both readings are common in the literature. They are not incompatible.
How the painting is made
The shield is wood, prepared by a Roman shieldwright with canvas glued across the convex surface. Caravaggio's oil paint sits on the canvas, which sits on the wood. The painting is not flat. The face curves outward with the shield. The serpents writhe slightly along the curve. The drop of blood at the bottom edge is painted exactly where the curve of the shield would actually make a drop run.
The technique is the early Caravaggio at his most confident. The flesh is built up in thin layers over a dark underground, the way a Lombard painter would build a face. The serpents are painted with a precise, almost diagrammatic anatomy — each snake has a recognisable species, several of them are native to central Italy, and one of them is being itself swallowed by another. The hair is not symbolic; it is studied, like a still life of living animals. The eyes are wet — Caravaggio paints the moisture on the eye with a single, slightly-translucent highlight on each pupil.
The picture has been x-rayed and infrared-scanned several times since the 1960s. The most striking finding is that Caravaggio painted the Medusa onto an earlier, abandoned attempt at the same subject on the same shield — a first Medusa, painted in 1596, that the painter scraped and started over. The second Medusa, which is the one we have, was probably the one that travelled to Florence as the diplomatic gift. The first Medusa is now under the second, visible only on the x-ray plate.
Why the painting still works
Four hundred and thirty years later, the Medusa shield is still one of the few paintings in European art that succeeds at the basic task of inducing a small physical recoil in the viewer. Stand in front of it in person and the painting takes about half a second to read. The scream is recognisable as a real human scream — open mouth, taut throat, wide eyes — before the viewer registers the snakes in the hair and the severed neck. The shock arrives in the wrong order: first the human face, then the inhuman situation.
This is the painting that begins Caravaggio. Everything that comes afterward in his short career — the religious paintings of dramatic darkness and sudden light, the genre paintings of card sharps and lute players caught mid-gesture, the late biblical pictures of beheadings and martyrdoms — descends from the discovery Caravaggio made on this small wooden shield in 1597. A painted face caught in a half-second of high feeling, lit from a single direction, against a dark ground, with the violence not symbolised but shown.
The shield is one of the smallest objects in Caravaggio's catalogue, and one of the most influential. Bernini, who was a child of one when it was painted, would later say that the only painter who had ever rivalled sculpture was Caravaggio. The Medusa shield is what he meant.
Key takeaways
Caravaggio's Medusa (1597) is painted in oil on canvas mounted on a convex wooden shield, about 55 cm in diameter. It is one of the smallest pictures in his catalogue and one of his earliest masterpieces.
The shield was commissioned by Cardinal del Monte in Rome as a diplomatic gift to Grand Duke Ferdinand I de' Medici in Florence, where it has been ever since.
Caravaggio paints the Medusa as she appears in the reflective surface of Perseus's polished shield at the half-second after the decapitation — mouth still open, snakes still alive, eyes still moving.
The face of the Medusa is the painter's own. Caravaggio used himself as the model, comparing with the contemporary Bacchus and Sick Bacchus self-portraits. The reasons (intellectual joke, self-knowledge of violence) are still debated.
X-ray analysis has shown an earlier, abandoned 1596 Medusa underneath the surviving 1597 picture. Caravaggio scraped and re-started the painting on the same shield.
The Medusa is the picture in which Caravaggio first paints a face caught in a half-second of extreme feeling, lit from one direction against darkness. Everything in his later career descends from this small wooden shield.
