Leonardo’s Last Supper contains numerous deliberate symbolic and compositional details: the apostles are arranged in four groups of three (a Trinity reference), Judas alone leans backward and clutches a money bag, the vanishing point of the entire perspective system aligns with Jesus’s right temple, and the groupings of the apostles spell out the word ‘Lumen’ in some scholarly readings. The figure to Jesus’s right is John, not Mary Magdalene — a persistent myth with no scholarly basis.
The Last Supper rewards preparation more than almost any other painting in the world. With 15 minutes in the room, visitors who know what to look at see a completely different painting from those who arrive cold. This guide gives you everything you need before you walk in.

The painting depicts the moment described in the Gospel of John (13:21): Jesus, at supper with his twelve apostles, has just announced, ‘Verily I say unto you, that one of you shall betray me.’ Every apostle reacts. Leonardo captures the precise psychological instant of revelation — not a tableau, but a room full of people responding in real time to a devastating announcement. For more on the painting’s history and technique, see our full Last Supper painting guide.
The twelve apostles are arranged in four groups of three on either side of Jesus. From left to right: Bartholomew (leaning forward), James Minor, Andrew (hands raised), Judas (clutching money bag), Peter (holding knife), John (calm, to Jesus’s right), then Jesus, then Thomas (finger raised), James Major (arms spread), Philip (hand to chest), Matthew, Thaddeus, and Simon. Judas is the only one leaning backward from Jesus.
| Position (left to right) | Apostle | Gesture / Key Detail |
| 1 | Bartholomew | Leaning forward on the table, alert |
| 2 | James Minor | Hand on Peter’s shoulder |
| 3 | Andrew | Hands raised, palms outward — a gesture of shock |
| 4 | Judas | Leaning backward, hand on table, clutching money bag in shadow |
| 5 | Peter | Leaning toward John, holding a knife behind his back |
| 6 | John | Calm; the youngest apostle, to Jesus’s immediate right |
| Jesus | — | Centre, arms extended, face downcast |
| 8 | Thomas | Finger raised — the gesture that echoes his later doubt |
| 9 | James Major | Arms spread wide — the most visually dramatic gesture |
| 10 | Philip | Hand to chest, imploring — ‘Lord, is it I?’ |
| 11 | Matthew | Turned toward Thaddeus and Simon |
| 12 | Thaddeus | Shrugging, turning away from Jesus |
| 13 | Simon | Hands spread on the table |
Judas is the fourth figure from the left, immediately to Peter’s left. He is the only apostle leaning backward from Jesus rather than toward him. His right elbow rests on the table; his left hand, partially in shadow, holds a small bag — the thirty pieces of silver, the price of the betrayal. His face is in relative darkness compared to the other apostles. A salt shaker (a symbol of bad luck and betrayal in the period) is in the process of tipping over where his arm disturbs the table.
Most visitors scan the painting from Jesus outward and miss Judas entirely. He is not obviously highlighted — Leonardo subverted the compositional convention of isolating Judas on the opposite side of the table (as earlier depictions of the scene always did) and placed him among the other apostles, distinguished only by his posture, his shadow, and what his hand is doing.
Leonardo engineered The Last Supper as a visual extension of the refectory it is painted in. The coffered ceiling in the painting appears to continue the real ceiling. The tapestries on the painted walls mirror the real walls. All receding lines in the painting converge at a single vanishing point — placed precisely at Jesus’s right temple. This is both a perspective device and a symbolic one: the mathematical and spiritual centre of the composition are the same point.
Standing at the original viewing distance (about 9 metres from the painting), the room and the painting read as a single space. Leonardo calibrated this precisely: the horizon line in the painting aligns with the eye level of a standing observer. You are, effectively, a fourteenth person at the table.
The twelve apostles are arranged in four groups of three. This is not incidental — the number twelve divided by three, with Christ as the thirteenth figure at the centre, creates a composition organised around the Trinity. Some scholars have also noted that the emotional registers of each group — one group gesturing toward Jesus, one gesturing away, one imploring, one looking to others for explanation — create a narrative arc across the table.
Book This TourThe lower portion of The Last Supper was destroyed in 1652 when a doorway was cut through the south wall of the refectory. The feet of Jesus and several apostles were removed. Later restorations attempted to paint in replacements, but the 1999 restoration removed most of this overpainting and left the missing section largely as it is. The doorway is no longer there — it was bricked up — but the damage to the painting is permanent.
Several visitors, primed by Da Vinci Code speculation, look for a ‘mysterious disembodied hand’ holding a knife that appears unconnected to any apostle. This is Peter’s hand. Peter is leaning forward toward John, and the knife he holds is visible at his right wrist — difficult to trace to its owner from the angle, but fully accounted for in the composition.
In 2007, an Italian musician named Giovanni Maria Pala claimed to have found a hidden musical score in the arrangement of the apostles’ hands and the positions of the bread rolls on the table. The claim received significant media coverage. It has not been accepted by Leonardo scholars and is not considered credible in art historical literature.
Dan Brown’s novel popularised several claims about The Last Supper that have no basis in historical or scholarly fact: that the figure to Jesus’s right is Mary Magdalene rather than John; that a ‘V’ shape between two figures represents the sacred feminine; and that a disembodied hand points accusingly. None of these interpretations are supported by Leonardo’s own preparatory sketches, the written accounts of contemporaries, or art historical analysis.
The figure to Jesus’s right is John the Apostle. Leonardo’s preparatory sketches for the composition — which survive — identify this figure as John. The soft, beardless rendering is entirely consistent with how Leonardo depicts young men throughout his career and with how John is conventionally represented in Christian art.
Judas — fourth from the left, leaning backward, clutching the money bag. Most visitors miss him. Once you know what to look for, he is immediately visible and becomes the key to reading the entire composition.
John the Apostle — the youngest of the twelve, traditionally depicted as beardless and gentle. Leonardo’s own preparatory sketches confirm this identification. The Da Vinci Code’s Mary Magdalene theory has no scholarly support.
There are 13 figures: Jesus and the twelve apostles. That is exactly the number present at the Last Supper as described in the Gospels.
A tipped-over salt shaker appears near Judas’s arm — in 15th-century Italian culture, spilled salt was an omen of bad luck and treachery. Leonardo included it as a compositional symbol underscoring Judas’s role.
