Dr. Deyman's Anatomy Lesson
Story of a mutilated masterpiece: A fire destroyed most of the large group portrait, but Rembrandt's shortened body, open brain and light retain striking power.
A fragment that changes the whole way we look
What remains shows two surgeons around the corpse of Joris Fonteijn, an executed criminal supplied to the Amsterdam Surgeons' Guild. Doctor Jan Deijman opens the skull to examine the brain; his assistant Gijsbert Calkoen holds the bony cap. The body, lit from above and presented feet forward, seems to push the table out of the board.
But this image was not intended as a two-figure scene. The preparatory sketch reveals a vast composition with eight surgeons. The fire that occurred in 1723 in the Anthoniswaag, on the Nieuwmarkt, destroyed most of the canvas. The current fragment is therefore both a work by Rembrandt, the material trace of a catastrophe and the surviving center of a disappeared collective portrait.
Compared to the Doctor Tulp's anatomy lesson from 1632, the work of 1656 is more frontal, steeper and quieter. Tulp demonstrates the functioning of an arm in front of an attentive group; Deijman works on the brain while the corpse occupies the axis of gaze.
Six benchmarks to understand what we see
A guild order
The painting commemorates a public dissection and also serves as a collective portrait of the surgeons who financed their presence in the image.
An identified body
The corpse is that of Joris Fonteijn, executed convict. His social status fades before the civic and medical authority of the guild.
An open brain
The scene is at an advanced stage of dissection: the skull cap is removed and Calkoen presents it above the face.
An extreme shortcut
The feet appear very close and the head moves back. Rembrandt compresses the body in depth to place the viewer at the edge of the table.
A burned work
The 100 × 134 cm fragment is only a fraction of a canvas once about 245 cm high and 300 cm wide.
A witness sketch
A preparatory drawing preserved by the Amsterdam Museum allows us to find the general layout and the surgeons now lost.
The fragment was the core of a huge group portrait
The sketch is crucial because it prevents the fragment from being taken for the composition desired by Rembrandt. The body already occupied the central axis, but it was framed by architecture and several surgeons. The Amsterdam Museum indicates that the original canvas represented eight practitioners and measured approximately 245 × 300 cm: one of Rembrandt's largest paintings.
The fragment corresponds to the operational heart of the scene. The peripheral faces, probably essential for the sponsors, have almost all disappeared. The body of the condemned man has largely survived. This inversion is striking: the collective portrait financed by living men reaches us today dominated by the one whose identity and rights counted the least in the hierarchy of the time.
We cannot reconstruct colors, expressions and all relationships of gaze from a small drawing. The sketch establishes the general structure; it does not replace lost paint. Any digital reconstruction or graphic should therefore be presented as an informed hypothesis, not as a photograph of the original state.
The anatomy lesson was a civic genre before Rembrandt
In Amsterdam, public dissections are organized by the surgeons' guild. The city provides the body of an executed convict; the event is held in winter to slow decomposition and can attract students as well as a paying audience. THE praelector anatomiae leads the demonstration.
The resulting painting is not a neutral report. It must preserve the memory of the guild, honor the professor and give a satisfactory place to the participants. The painter therefore negotiates between science, professional prestige and portrait. Rembrandt overturns this compromise twice: in 1632 with an animated pyramidal composition, then in 1656 with a point of view which makes the corpse the optical axis of the entire room.
Perspective transforms the viewer into a witness
The corpse is seen from the feet. The legs form two lines that converge towards the pelvis, torso and open head. This construction is called shortcut: a body oriented in depth appears compressed on the surface flat. Rembrandt accentuates the effect by placing the table almost perpendicular to the board.
The result is not only virtuoso. The spectator finds himself at the edge of the table, in a position comparable to that of the anatomical theater audience. The body seems to move forward, but his face moves away. This tension prevents one comfortable contemplation: the enlightened flesh occupies the space, while the identity of the dead remains subject to the medical act.
The body is that of Joris Fonteijn, often nicknamed "Zwarte Jan" in historical sources. The Amsterdam Museum describes him as a convicted felon. More detailed accounts of his biography and execution must be handled with caution when not based on the same archival documents. The essential fact is institutional: after the death penalty, the city hands over the corpse to the guild.
A famous comparison, not proof of borrowing
Visible resemblance
In both works, an elongated body is presented from the feet. The legs lead to a shortened torso and a head located at the back. The viewer is placed facing mortality, without the protective screen of a side view.
Fundamental difference
Mantegna paints Christ mourned by his loved ones; Rembrandt shows the judicial corpse in the middle of a public demonstration. One belongs to Christian devotion, the other to corporate portraiture and the history of medicine.
Comparing the two shortcuts helps to see. Claiming that Rembrandt directly copies Mantegna would require historical proof that we do not possess.
Rembrandt knew Italian tradition through prints and his collection, but the similarity of a device is not enough to establish a precise source. Deijman's shortcut also responds to the real space of anatomical theater: it makes the painted gaze coincide with that of an audience placed in front of the table.
Twenty-four years separate two conceptions of the collective portrait
| Point of comparison | Doctor Tulp, 1632 | Doctor Deijman, 1656 |
|---|---|---|
| State of conservation | Complete canvas, 169.5 × 216.5 cm | Fragment of 100 × 134 cm; original composition estimated at €245 × 300 cm |
| Corpse | Adriaen Adriaensz, known as Aris Kindt | Joris Fonteijn |
| Anatomical moment | Demonstration of forearm muscles and tendons | Opening the skull and examining the brain |
| Viewpoint | Body seen sideways | Frontal body, feet forward, extreme shortcut |
| Organisation | Pyramidal group, varied looks | Monumental symmetry revealed by the sketch |
| Role of the teacher | Tulp explains with pliers and his left hand | Deijman intervenes directly on the brain; his face is lost |
| Dominant effect | Intellectual dynamism of a demonstration | Physical confrontation with the open body |
Anthoniswaag fire destroys most of the canvas
After the order, the painting belonged to the institutional environment of the surgeons' guild. It is installed in the Anthoniswaag, today's Waag of the Nieuwmarkt. In 1723, a fire seriously damaged the building and the painting. The canvas, once monumental, is reduced to the central fragment that we know.
This destruction should not be imagined as a simple aesthetic reframing. The fire alters or destroys most of the image; the recoverable part is then kept in a smaller form. The upper edge cuts it deijman's body and makes his face disappear. Of the seven other surgeons around the professor, only Calkoen remains complete enough to be visually identified in the fragment.
Material history thus modifies the interpretation. The current painting seems almost modern in its brutality, its tight framing and its truncated figures. Part of this effect belongs to Rembrandt - notably the shortcut and the light - but the framing that we see is also that of catastrophe.
Flesh lit against black clothes
The body forms the largest light area. Sheets, skin and surgical linens make up a series of whites, warm grays and ochres. Around, black clothes absorb light. This opposition detaches the corpse without it make abstract: the knees, stomach and face remain shaped by sensitive transitions.
In Rembrandt's late painting, the thickness is not uniform. Some lights are laid with more paste; shadows can remain thin and deep. The edges close or dissolve depending on their importance. Here, feet and legs should drive the gaze, while the environment is simplified.
The dark red of the linen or fabrics near the head introduces a warm accent near the exposed brain. It is not a guaranteed symbolic code, but a chromatic means of retaining the eye at the end of the perspective journey. Color organizes reading as much as drawing.
What the fragment allows us to assert - and what it does not prove
Established facts
- The painting is signed and dated 1656.
- This is an oil on canvas commissioned in the context of the Surgeons Guild.
- The dead man is Joris Fonteijn; Deijman leads the dissection and Calkoen assists him.
- The fragment measures 100 × 134 cm.
- The sketch attests to a much larger original composition with eight surgeons.
- The fire of 1723 destroyed most of the work.
Careful reading
- The shortcut can recall Mantegna, without demonstrating direct copying.
- Frontality can be understood as a way of involving the anatomical theater audience.
- Light gives visual dignity to the corpse, but does not prove conscious social denunciation.
- The "cinematic" aspect of the fragment is partly due to the cutting following the fire.
- The sketch allows a reconstruction of the structure, not a certain restitution of all colors and expressions.
Amsterdam for Deijman, The Hague for Tulp
The Amsterdam Museum preserves the fragment and the preparatory sketch. During the renovation of its main building, masterpieces from the collection are presented in other locations; the museum announced Deijman's exhibition in 2025 in the Gallery of Honor at the Rijksmuseum. Always check the official hanging before your visit.
Amsterdam
Doctor Deijman's Anatomy Lesson, Amsterdam Museum collection, inv. SA 7394; hanging announced at the Rijksmuseum.
The Hague
The Anatomy Lesson of Doctor Nicolaes Tulp, Mauritshuis, inv. 146, currently shown in room 9.
Milano
The dead Christ de Mantegna, Pinacoteca di Brera, allows you to compare two major solutions of the shortcut on site.
Six gestures to observe the fragment
Start with the feet
Follow the axis of the legs towards the head. Measure how Rembrandt compresses actual body length.
Identify the cuts
Observe the edges of the fragment: Deijman's body disappears upwards and the scene extended widely to the left and right.
Compare with sketch
Locate the area preserved in the full drawing. You will see that the fragment is only the center of the device.
Follow the light
Note where the flesh turns white, ocher, or gray, then how black clothing stops or absorbs lighting.
Identify actions
Calkoen holds the skullcap; Deijman acts on the brain. The table distinguishes assistance, demonstration and observation.
Compare with Tulp
Look at the orientation of the corpse, the number of faces, the role of the teacher and the anatomical concentration point.
Two anatomy lessons, two moments from his career
The store offers both works under their current museum attributions. The Deijman product corresponds to the fragment preserved by the Amsterdam Museum; the reproduction of Tulp corresponds to the complete painting of the Mauritshuis.

Why is the painting a fragment?
A fire in 1723 in the Anthoniswaag destroyed most of the canvas. Only the central section could be preserved.
How big was the original painting?
The Amsterdam Museum estimates its dimensions at around 245 × 300 cm. The current fragment measures 100 × 134 cm.
Who is the dead person depicted?
Joris Fonteijn, executed convict whose body was handed over by the city to the guild of surgeons for public dissection.
Who are Deijman and Calkoen?
Jan Deijman is the anatomy professor who works on the brain. Gijsbert Calkoen, his assistant, holds the skullcap removed.
Why do we see the body from the feet?
This shortcut places the viewer at the edge of the table and makes it appear as if the corpse is moving out of the painted surface.
Was Rembrandt inspired by Mantegna's dead Christ?
The comparison is visually relevant, but there is no documentary evidence to support a direct borrowing from this specific work.
What's the difference with Tulp's Anatomy Lesson?
In 1632 Tulp showed a demonstration of the forearm in a diagonal composition; In 1656 Deijman showed the brain in a much stronger frontality.
Where to see the fragment today?
It belongs to the Amsterdam Museum. The museum has announced its temporary hanging in the Gallery of Honor at the Rijksmuseum; check the tour instructions before traveling.
