Rembrandt Night Watch: Three Attacks, 44.8 Gigapixels of Missing Edges, and Why It Is Not Actually at Night

Last updated: May 2026 · By Stanislav Arnautov · Berlin

Rembrandt Harmenszoon van Rijn (Leiden, 1606 – Amsterdam, 1669) painted the Night Watch (De Nachtwacht) in 1642, when he was 35–36 years old. The painting is oil on canvas, 363 × 437 cm in its current cropped state (see below). The Rijksmuseum Amsterdam displays it in the Eregalerij (Gallery of Honour) in a purpose-built room that accommodates the painting's full scale and allows the approximately 1 million annual visitors who see it to approach within a few metres. The Night Watch is the centrepiece of the Rijksmuseum's collection and the most visited single artwork in the Netherlands. DeckArts Berlin reproduces the Night Watch from approximately $140 (single deck) to $310 (triptych) on Grade-A Canadian maple, shipping from Berlin.

What the Night Watch Actually Depicts

The Night Watch depicts the Civic Guard company (schutterij) of Captain Frans Banninck Cocq (in black, with red sash, left of centre) and his lieutenant, Willem van Ruytenburch (in yellow, right of centre), in the moment of marching out — specifically the moment when the company is assembling and beginning to move, rather than a formal posed portrait. This is the specific innovation of the Night Watch within the Dutch civic guard portrait tradition: prior guard portraits had depicted the company in formal seated or standing group poses, with each member given equal visual prominence. Rembrandt depicted the company in motion, with the most prominent figures given narrative roles (Cocq gestures, Ruytenburch listens, the girl in the background runs forward, the musketeer loads his weapon) and many figures partially obscured by the compositional density and dramatic lighting.

The commission was unusual: Cocq's company paid for the painting collectively, with each member contributing a fee proportional to his visual prominence in the composition. The members who are fully visible and centrally placed paid more than those who are partially obscured or in the background. This meant that Rembrandt's compositional choices directly determined his income from the commission, and that the relatively low visibility of some background figures created contemporary dissatisfaction. Whether the dissatisfaction significantly damaged Rembrandt's reputation at the time is debated by historians; the traditional narrative that the Night Watch was considered a failure and damaged Rembrandt's career is not supported by the documentary evidence.

The two foreground figures — Cocq (black, red sash) and Ruytenburch (brilliant yellow, white sash) — are depicted at approximately life scale in the original 363 × 437 cm canvas. The specifically warm-cool palette contrast between Cocq's near-black clothing and Ruytenburch's brilliant chrome yellow is the painting's primary chromatic event, and the specific contrast that survives most powerfully in the DeckArts triptych reproduction. The triptych captures the central section of the composition including both primary figures and the golden-dressed girl in the background, who is typically identified as a company mascot or allegorical figure.

Three Attacks: 1911, 1975, and 1990

The Night Watch has been attacked three times in its history, making it the most physically threatened canonical painting in a major European museum:

1911: A cook named Sigmund Carl Van den Berg attacked the painting with a shoemaker's knife, making several cuts in the canvas. The damage was repaired, and the incident prompted the first serious security review at the Rijksmuseum for the Night Watch specifically. The 1911 attack was attributed to a personal grievance (Van den Berg reportedly believed he had been dismissed unjustly from a government position) rather than to political or ideological motivation.

1975: A former primary school teacher named Wilhelmus de Rijk entered the Rijksmuseum and attacked the Night Watch with a bread knife, making 12 cuts in the lower left portion of the canvas. The attack lasted several minutes before De Rijk was restrained; he had entered the museum during normal visiting hours and walked directly to the Night Watch. The damage was significant and required extensive restoration. De Rijk was subsequently committed to a psychiatric facility. The 1975 attack prompted major security upgrades including controlled barriers around the painting.

1990: A visitor threw acid at the Night Watch. The Rijksmuseum's protective barriers prevented the acid from reaching the painted surface directly; the damage was limited to the protective varnish layer applied after the 1975 restoration. The security barriers that stopped the acid were installed specifically as a consequence of the 1975 attack. The 1990 acid attack is therefore the case in which a previous attack's security response directly prevented a subsequent attack from causing significant damage.

The Night Watch is currently displayed behind bullet-resistant glass within a purpose-built environmental monitoring and security system. The glass is specifically formulated to preserve the painting's optical qualities while providing physical protection: anti-reflective, UV-filtering, and optically clear to maintain the warm tenebrism's visual quality. The security system includes movement sensors, temperature and humidity monitoring at 15-minute intervals, and a dedicated conservation team that examines the painting annually.

The 2021 AI Reconstruction: 44.8 Gigapixels of Missing Edges

In 2021, the Rijksmuseum announced the completion of an AI-powered reconstruction of the Night Watch's missing edges — the portions of the painting that were cut off when the canvas was trimmed in 1715 to fit a narrower doorway (see below). The reconstruction project used a neural network trained on Rembrandt's other works and on the Night Watch's own paint surface to generate a plausible reconstruction of the missing edge content, extending the composition by approximately 60 cm on the left, 22 cm at the top, and 12 cm at the right and bottom.

The AI reconstruction was technically based on a copy of the Night Watch made in the 1640s by Gerrit Lundens (now at the National Gallery, London), which shows the full original composition before the 1715 trimming. The Lundens copy provided the reference for what the missing content depicted; the AI's task was to render that content in Rembrandt's own paint surface style, at the colour and detail quality of the Night Watch's actual paint layers, rather than at the relatively crude quality of the Lundens copy.

The result — a 44.8-gigapixel composite of the actual Night Watch and the AI-reconstructed edges — was printed and displayed around the Night Watch in the Rijksmuseum as a border, showing visitors what the full original composition looked like. The AI-generated content specifically adds: on the left, two additional full figures and parts of two more (including a drummer who had been completely cut off); at the top, additional architectural elements of the building behind the company; and at the right, a partial figure and more architectural context.

The Missing Edges: Why the Painting Was Cut

The Night Watch was trimmed in 1715, when it was moved from the Kloveniersdoelen (the Amsterdam Civic Guard Hall where it had hung since 1642) to the Amsterdam Town Hall (now the Royal Palace on Dam Square). The trimming was made to fit the canvas through a doorway that was narrower than the painting's full width: the left side was trimmed most significantly (removing approximately 60 cm), the top was trimmed slightly, and the right and bottom edges were trimmed minimally. The decision to trim a 363 cm canvas to fit a doorway rather than to use a different doorway or to disassemble the canvas and re-stretch it on the other side of the door — which would have been more labour-intensive but would have preserved the full composition — is one of the most consequential logistical decisions in Dutch art history.

The Gerrit Lundens copy in the National Gallery London (the primary documentary evidence for the original composition) shows that the original canvas depicted a composition wider by approximately 60 cm on the left side, adding two full additional figures — members of the guard company who paid for their inclusion and who were physically removed from the painting by the 1715 trimming. The specific artistic consequence: the drumming figure at the left edge of the original composition, who provided the musical structure for the company's marching action, is completely absent from the current canvas. The Night Watch as currently displayed has lost its musical dimension — the drum that gave the march its rhythm is gone.

Warm Tenebrism: Why the Night Watch Is Not Actually at Night

The title "Night Watch" (De Nachtwacht) was not applied to the painting by Rembrandt — it is an 18th-century nickname that stuck. The painting does not depict a night scene: the compositional lighting is a daytime scene with deep indoor shadow (the Kloveniersdoelen entrance hall) and bright sunlight coming from the upper left. The dark varnish layers accumulated over the 17th, 18th, and early 19th centuries gave the painting its characteristic dark appearance, which the 18th-century observers interpreted as a night scene and named accordingly. The 1947 cleaning at the Rijksmuseum removed several layers of discoloured varnish and revealed the original palette — which is significantly lighter and warmer than the "Night Watch" name suggests.

The painting's specific tenebrism is warm: the principal warm highlights are Captain Cocq's white collar and cuffs, Ruytenburch's brilliant chrome yellow suit, and the golden-dressed girl in the background. Rembrandt's warm near-black shadows — raw umber and burnt sienna dominant, at approximately 2800–3000K warm colour temperature — create the specific tenebrism that advances the warm highlights from the dark without the cold confrontational quality of Caravaggio's cooler tenebrism. The Night Watch is warm throughout: the shadows are warm, the highlights are warm (chrome yellow, white, gold), and the only cool element is the Prussian blue sky visible at the upper edges of the composition.

For the DeckArts installation, the warm tenebrism has specific requirements: warm LED at 2700K is not optional but mandatory. Under cool LED at 4000K+, the chrome yellow of Ruytenburch's suit reads as flat synthetic yellow, the warm near-black shadows lose their warm undertone and become cold dark, and the entire tenebrism system — the warm advancement from warm dark — fails. Under 2700K warm LED, the chrome yellow advances at full warm luminosity, the warm darks provide the rich ground from which the warm highlights emerge, and the Night Watch's warm tenebrism performs as Rembrandt designed it in the candlelit guild hall of 1642.

The Rijksmuseum Room: Purpose-Built for One Painting

The Night Watch room at the Rijksmuseum Amsterdam — the final room of the Gallery of Honour (Eregalerij) — was purpose-built to display the Night Watch at its full 363 × 437 cm scale. The room's dimensions allow viewers to stand 10–15 metres from the painting — the viewing distance at which the composition reads at its designed scale. The Night Watch was painted for the Kloveniersdoelen entrance hall at a comparable viewing distance: the building's entrance hall was approximately 12 metres deep, and the painting was hung at the hall's far end, designed to be read across the room's full depth.

The Rijksmuseum receives approximately 2.5 million visitors per year; the Night Watch room is visited by essentially all of them. The conservation team conducts visual examination of the painting weekly and detailed technical examination annually. The controlled environment maintains temperature at 19–21°C and relative humidity at 50–60% year-round. The lighting is warm LED at approximately 2700–3000K, directed at the painting from ceiling track spots at a 30–40 degree angle from vertical — the same warm directed illumination that the DeckArts installation guide recommends for domestic installations.

Night Watch for Living Room: The Authoritative Installation

The Night Watch triptych (~$310) above the sofa on the primary living room wall is the most authoritative classical art living room installation in the DeckArts range. "Authoritative" in a specific sense: the Night Watch depicts a company of citizens in their most formal and most active public role — the civic guard, armed and assembled, marching out to defend the city. Above the sofa in the living room — the household's most social and most public room — the Night Watch argues that the people in this house take their civic responsibilities seriously, that they value order and the collective, and that they live in the tradition of the active civic life that the Dutch Golden Age represented at its most significant.

The living room sizing: triptych (~70 cm wide, ~$310) for sofas 120–140 cm; 4-deck gallery (~95 cm, ~$430) for sofas 160–180 cm. Height: art centre at 155–165 cm from floor, 15–20 cm above sofa back top. Wall colour: forest green (most historically coherent), deep burgundy (most intimate), warm charcoal (most contemporary). Under warm LED 2700K, ceiling track spot at 30–40 degrees.

Night Watch on Forest Green: The Most Historically Coherent Wall

Forest green is the most historically coherent wall colour for the Night Watch triptych because Rembrandt's warm near-black shadows — raw umber and burnt sienna at approximately 2800–3000K — are warm-dark in the same colour register as the forest green wall's organic warm dark (~4000–4500K). The colour temperature differential between Rembrandt's warm darks and the forest green wall is smaller than between those warm darks and any cool dark wall (navy or charcoal), which means the painting's warm tenebrism merges smoothly into the forest green's organic warmth rather than creating a perceptible colour boundary at the painting's edges.

The practical result: on a forest green wall, the Night Watch's deep warm shadow zones appear to extend into the wall — the painting seems to emerge from and recede into the same warm organic dark. The chrome yellow of Ruytenburch's suit, the white of Cocq's collar, and the gold of the background girl's dress advance from this continuous warm organic field as the only luminous warm elements in the visual field. Aged brass floor lamps and warm linen on the sofa below complete the material argument: warm organic materials (teak wood, linen, botanical green) supporting the warm-tenebrism painting that was designed for exactly this warm-material environment.

FAQ

Has the Night Watch been attacked?

Yes — three times. 1911: Sigmund Carl Van den Berg attacked the canvas with a shoemaker's knife (personal grievance). 1975: Wilhelmus de Rijk attacked with a bread knife during normal visiting hours, making 12 cuts in the lower left (12 cuts, restored; De Rijk committed to psychiatric facility). 1990: visitor threw acid; protective barriers installed after the 1975 attack prevented the acid reaching the painted surface. The Night Watch is now behind bullet-resistant glass with a purpose-built security system. DeckArts triptych from ~$310.

What is the Night Watch AI reconstruction?

In 2021, the Rijksmuseum completed a 44.8-gigapixel AI reconstruction of the Night Watch's missing edges — the portions cut in 1715 to fit a narrower doorway (approximately 60 cm cut from the left, removing a drummer and other figures). A neural network trained on Rembrandt's works reconstructed the missing content based on the Gerrit Lundens 1640s copy (National Gallery London) which shows the full original composition. The AI reconstruction was displayed as a printed border around the actual Night Watch in the Rijksmuseum, showing the full original composition including the missing drum. DeckArts from ~$310.

Why is the Night Watch called the Night Watch?

The title "Night Watch" (De Nachtwacht) was not applied by Rembrandt — it is an 18th-century nickname that resulted from the painting's dramatically dark appearance after centuries of varnish discolouration. The 1947 cleaning at the Rijksmuseum removed discoloured varnish layers and revealed the original palette, which depicts a daytime scene (the Kloveniersdoelen entrance hall in daylight). The specific tenebrism is warm — raw umber shadows and chrome yellow highlights — not a night scene. The misleading name has been standard for approximately 250 years. DeckArts from ~$310.

What size was the original Night Watch?

The Night Watch's original size, before the 1715 trimming, was approximately 423 × 437 cm — approximately 60 cm wider on the left side than the current 363 × 437 cm. The trimming removed approximately 60 cm from the left (cutting off a drummer and additional figures), approximately 22 cm from the top, and minor amounts from the right and bottom. The trimming was made to fit the canvas through a doorway when the painting was moved from the Kloveniersdoelen to Amsterdam Town Hall in 1715. The Gerrit Lundens copy (National Gallery London, 1640s) shows the full original composition. DeckArts triptych from ~$310.

What wall colour goes with the Night Watch?

Forest green (#2D5016) is the most historically coherent wall colour for the Night Watch: Rembrandt's warm near-black shadows (~2800–3000K) merge smoothly into the forest green's organic warm dark (~4000–4500K), creating a continuous warm organic field from which the chrome yellow and warm flesh advance at maximum luminosity. Deep burgundy creates warm-warm velvet richness. Warm charcoal creates cool-neutral contemporary depth. All require warm LED 2700K — the chrome yellow loses its luminosity under cool LED. DeckArts from ~$310.
