Architecture of a masterpiece: Leonardo's perspective, mapped. Look closer. Do you see what's happening here? www.geometrylastsupper.com #TheLastSupper #LeonardoDaVinci #RenaissanceArt #ArtHistory #Geometry #GeometryInArt #SymbolismInArt

Leonardo da Vinci's "The Last Supper" overlaid with a geometric grid and perspective lines. Bright yellow perspective lines suggested by the top of the tapestries, originate from the upper corners and converge at the vanishing point on Jesus’s head. A blue triangle with its sides on the diagonals of the grid and its apex at the centre. Two white semi-circular arcs show the rotations of the triangle's sides. The perspective lines are tangent to the arcs, as if resting on them. The angle between the hands of James and Thomas is the same as the angle of the arc.

🤓 Nerd’s corner: for the truly dedicated geometry fans... what is the height of the vanishing point B? geometrylastsupper.com #TheLastSupper #LeonardoDaVinci #RenaissanceArt #ArtHistory #Geometry #GeometryInArt #SymbolismInArt

From The Geometry of the Last Supper by Raphaël Mouterde. It shows the triangle on the grid and the arc created by the rotation of the side of the triangle to the vertical. The main perspective line suggested by the top of the tapestries has the same slope than the diagonal of the grid and is tangent to the arc.

000

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 19/01/2026

And here lies the beauty of it: 💡 The perspective lines are tangent to the Arc of Thomas! This connection reveals yet another layer of deliberate geometry within the composition, in an elegant alignment between the triangle, the grid, and the perspective itself.

110

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 19/01/2026

Or so it seems. In fact, the perspective lines are related to the grid because their slope matches that of the grid's diagonals. In other words, the perspective (in yellow) runs parallel to the diagonals of the grid (in black).

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 19/01/2026

The Triangle #5 One of the strongest contributors to the illusion of depth in the Last Supper is the series of tapestries lining the walls on either side of the dining room. Their position and size follow the grid, but the main perspective lines suggested by the top edges of the tapestries do not.

As we can see, the angle formed by their hands is strikingly close to the angle of the arc – hence the name I've given it: the Arc of Thomas. The Arc of Thomas has already provided us with the height of the windows, but it has yet to play another important role.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 15/01/2026

The Triangle #4 The arc created by rotating the triangle’s side aligns the top point A with one of the grid's verticals. Here, I've highlighted the angle of this arc in yellow and reported it to the hand gestures of James and Thomas.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 09/12/2025

This means the height of the door and windows are defined twice, leaving little doubt that geometry played a deliberate role in establishing the dimensions of these openings. 🤓 Nerd’s corner: the scientifically inclined among us will easily figure out the height of the openings.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 09/12/2025

Those who have followed this mini-series from the beginning might think: «But we’ve already defined the height of the window in a previous post!» And they would be absolutely right. Remarkably, both rotations – of the triangle’s side and of its base – meet the grid at precisely the same point.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 09/12/2025

The Triangle #3 Our attention turns to the rotation of the triangle’s sides. 📐 Once again, let’s take our imaginary drawing compass. Placing the tip on N, we rotate the top of the triangle to the right. Starting from A, we trace an arc that intersects the grid exactly at the height of the window

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 04/12/2025

So the question is: what is the radius of that circle? 💡 The first intuition is the correct one: the pediment is defined by a circle of radius 1 (one module of the grid = 1). #TheLastSupper #LeonardoDaVinci #RenaissanceArt #ArtHistory #Geometry #GeometryInArt #SymbolismInArt geometrylastsupper.com

From The Geometry of the Last Supper by Raphaël Mouterde. It shows the triangle on the grid and the arcs created by both rotations of the triangle's base. The outer edge of the pediment is given by the circle of radius 1 (module of the grid) coming into contact with the arcs at a tangent.

000

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 04/12/2025

📐 By placing our compass on M, the rotation of the triangle’s base gives us a mirror image of the arc traced previously. Together, these arcs outline the silhouette of a Gothic arch. Since this arch touches the pediment at a tangent, it means that a circle must have been used to draw its outer edge

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 04/12/2025

The Triangle #2 “What are the chances that three points chosen at random would line up?” This question came to my mind as I contemplated the arc created by rotating the triangle’s base, and how precisely it fits the painting. With the arc tangent to the pediment, its construction unfolded with ease

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 29/11/2025

This is quite remarkable: in a single movement, our compass reveals three major clues, each one bringing us closer to understanding the underlying harmony of this extraordinary composition. #TheLastSupper #LeonardoDaVinci #RenaissanceArt #ArtHistory #Geometry #GeometryInArt geometrylastsupper.com

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 29/11/2025

• As the base rotates, the arc first meets one of the vertical grid lines. This intersection aligns precisely with the top of the window opening. • Higher up, the arc becomes tangent to the decorative pediment. • The arc intersects with the grid a final time at the height of the cornice.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 29/11/2025

The Triangle #1 Starting from the centre of the grid and following Jesus’ open arms, we can draw a triangle with a base of 4 and a height of 2. 📐 Let’s grab an imaginary compass, plant it on N, and rotate the triangle’s base upward. With that gesture, we draw an arc that interacts with the grid.

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 10/11/2025

And this, ladies and gentlemen, is the key to the geometry of The Last Supper! From this single triangle, one can derive the height of the windows and door openings, the construction of the pediment above the door, and the placement of the cornice. Can you see how?

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 10/11/2025

Furthermore, Christ’s left hand, opening up in a gesture of offering, visually balances the movement initiated by his right hand as it turns towards the morsel of bread. But, if we were to extend downwards the triangle suggested by the posture of Christ, we would end up with a triangle of base 4.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 10/11/2025

The Triangle Whether the posture of Jesus, with his arms open before him, was intended to represent a triangle is debatable. There are plenty of good reasons to depict Christ in such a stance. It conveys a sense of calm and inner authority which contrasts sharply with the agitation of the disciples

From The Geometry of the Last Supper by Raphaël Mouterde. It shows a close-up of Jesus and the first group of disciples seated next to him on either side. There is an overlay of the grid with the triangle of base 4, height 2 and its apex at the centre of the grid. The open arms of Jesus suggest such a triangle, key to the geometry of the Last Supper.

The 3 centres are part of a unique geometrical design. Not only is it beautiful in its clarity and efficiency, but the symbolic meaning concealed within it forms a spiritual message – hidden, yet profoundly present – at the heart of The Last Supper. geometrylastsupper.com #LeonardoDaVinci

If we assume for a moment that these centres are indeed connected, we would have to examine the reasons behind their arrangement. One explanation could be the logical outcome of a geometrical construction; another, the result of a deliberate choice infused with symbolic meaning. #TheLastSupper

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 04/11/2025

Visually, the importance of the vanishing point is indisputable, since it commands the viewer’s attention, while the centre of the pediment belongs to a modest ornament, and the grid’s centre is virtually invisible. Yet, this raises a crucial question: is their placement purely coincidental?

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 04/11/2025

Three centres for The Last Supper? With the presentation of Brachert’s grid in the last mini-series, things seem at first to get a little out of hand. 📐 In effect, the composition has three different centres: •The centre of the grid itself •The vanishing point •The centre of the pediment

From The Geometry of the Last Supper by Raphaël Mouterde. It shows the Last Supper with an overlay of the 12x6 grid and elements of the composition that don't fall on the grid, i-e: the perspective, the pediment and the openings of the windows and the door with its decorative pediment.

It shouldn’t come as a surprise to find architectural elements in The Last Supper that disobey the grid’s rigid order. After all, its inherent inflexibility limits creativity. Yet, it is in these departures from order that the geometry itself starts to speak.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 26/10/2025

Notably, the arrangement of the four groups of apostles follows the grid’s boundaries. However, what truly sparks our interest are the elements that seem to defy the grid: the openings of the windows and the door don’t align with it. The pediment and the main lines of perspective don't conform.

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 26/10/2025

The Grid #6 The grid acts as a structural framework for the proportions of the entire scene. It dictates the placement of key elements: the dining room’s walls, the ceiling, the back wall, the table and the floor. It also informs the positioning of the tapestries on either side of the composition.

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 21/10/2025

To the far left, James the Minor, dressed in pink and part of the first group of apostles, reaches out to touch Peter’s shoulder, trying to draw his attention. His palm faces downward, almost flat, with the back of his hand positioned precisely at the level of the median. #Geometry #GeometryInArt

000

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 21/10/2025

This subtle detail visually signals his moral and emotional descent. Counterbalancing his downward motion, Philip rises above the median, his hands pressed on his heart, contributing to the wave-like motion that animates the composition. #TheLastSupper #LeonardoDaVinci #RenaissanceArt #ArtHistory

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 21/10/2025

The Grid #5 The median is the horizontal line of the grid that runs through its centre. In The Last Supper, the median of Brachert's grid aligns with the heads of all the protagonists but one. Judas, the one who will betray Jesus, is the only person whose face falls below the line.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 17/10/2025

On the left, Judas leans back on his elbow, generating a downward tilt that is counterbalanced on the right by the upright posture of Philip who stands behind James and Thomas. As the wave moves outward toward the edges of the composition, it looses intensity and gradually flattens. #TheLastSupper

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 17/10/2025

The Grid #4 There is a wave-like motion running through the disciples. Those closest to Jesus express the most intense emotions, in stark contrast to the figures at the far ends of the table. The amplitude of this emotional "wave" is highest near Jesus and gradually flattens as it stretches out.

100

The Geometry of the Last Supper @geometrylastsupper.bsky.social · 12/10/2025

This leaves two units in the centre occupied by Jesus alone, giving rise to a sense of authority and calm amid the chaos around him. #TheLastSupper #LeonardoDaVinci #RenaissanceArt #ArtHistory #Geometry #GeometryInArt #SymbolismInArt
