Saint Ambrose and Theodosius

An emperor reaches the steps of a church and finds his way blocked by an open hand. Anthony van Dyck brings the encounter close enough for us to follow the pressure of bodies, the meeting of outstretched arms and the glances passing between the two groups. Red cloth and a magnificent gold cope give the confrontation its colour; a small dog helps unlock its story.

An encounter on the steps

Theodosius stands near the centre, wearing armour, a red cloak and a laurel wreath. Ambrose, Bishop of Milan, faces him from the right. The emperor's forward movement has met the bishop's raised palm. Below that commanding gesture, another hand extends across the narrow interval between them. The arms make a small, tense network at the centre of the picture, where a passage ought to open.

Van Dyck makes the emperor easy to find. The red cloak gathers over his shoulder and descends in a broad, irregular fold beside his legs. Its warmth stands out against the grey stone, while the exposed knee and the forward foot bring the action down to the steps. His body inclines towards the bishop. We can read that inclination as an approach checked in mid-movement, without needing to imagine the words he is speaking.

Ambrose has a different kind of presence. His mitre rises above the heads around him, and his cope spreads into a great curved surface of gold ornament on black. Its abundance almost gives the cloth the weight of a wall. Beneath it, pale fabric falls to the step. His hand is comparatively small, but the surrounding drapery and upright architecture lend it force. An emperor with soldiers behind him has been stopped by a gesture.

The groups remain distinct even where they overlap. On the left, bare arms, armour and the slant of weapons give the imperial followers a restless, angular outline. On the right, heads gather around the bishop beneath the shelter of the masonry. A young attendant seen from behind occupies the foreground in white. The broad, bright back of his garment gives the eye somewhere to rest amid so many faces and patterned surfaces. His turned head also directs us back towards the argument.

There is little open ground between the participants. Yet the shallow steps matter enormously: they make the church entrance a place of approach, resistance and possible admission. The scene can be understood before its historical names are known. Someone who expects to advance has reached a boundary.

The story in the Golden Legend

The National Gallery relates the emperor's punishment to the massacre at Thessalonica after the killing of his general, Butheric. The Golden Legend , Jacobus de Voragine's medieval collection of saints' lives, supplies the extended confrontation, the intervention of Ruffin and the subsequent repentance. The Caxton translation presented here calls the emperor Valentinian in this passage; the Gallery identifies the painted protagonist as Theodosius. That discrepancy should remain visible when the text and painting are read together. ^{[1] [2]}

In the medieval account, Ambrose challenges the ruler's bloodstained hands and demands that reason govern power. The emperor withdraws in distress. Ruffin, master of his knights, offers to obtain absolution, but receives the bishop's own fierce rebuke. Eventually the emperor accepts public penance. Even after reconciliation, Ambrose requires him to leave the chancel and stand with the lay congregation. ^[2]

The sequence gives the painted threshold a future as well as a present. The ruler stands outside, but the possibility of return remains. Access to worship is the point at which his power meets a limit.

The Golden Legend is a medieval retelling of a much earlier event. Its speeches and detailed narrative belong to that literary and devotional tradition; they cannot serve as a contemporary transcript of the encounter. ^[2]

Follow the bishop's eyes

The emperor occupies the centre of the confrontation, but Ambrose's gaze reaches towards the man at the far left. This is Ruffinus, the Ruffin of the medieval narrative. The dog's presence at his feet connects him with the bishop's comparison of his shamelessness to a hound. ^{[1] [2]}

Once that connection is noticed, the painting opens sideways. The action no longer passes only between the two main figures. Ambrose's raised hand blocks the emperor while his eyes engage a follower beyond him. A glance carries the argument further than a hand can reach.

Ruffinus stands with an exposed arm bent outwards and his hand near his hip. The pose gives him breadth and a conspicuous place at the edge of the gathering. His head turns into the scene, but the broad chest and planted stance keep him visually apart from the emperor's forward inclination. The two men belong to the same retinue while presenting very different arrangements of the body.

The dog is low down, close to the emperor's boots and the bottom edge. Its lifted head makes a small upward movement beneath the descending folds of the red cloak. It is easy to register it first as a lively detail in a solemn gathering. The tale gives that detail a sharper purpose: an animal on the steps becomes a visual reminder of a spoken accusation.

Looking back from the dog to Ruffinus, and then along Ambrose's gaze, connects the low foreground to the most intense part of the encounter.

Stone, cloth and the balance of authority

The upper part of the painting is divided between troubled sky and heavy architecture. Clouds and the diagonal points of weapons leave the left edge open and unsettled. On the right, columns and projecting blocks of stone build a dense enclosure. Their verticals continue down towards the bishop's body, giving his position a firm visual backing.

Above the figures, the architecture is large, impersonal and enduring; at their feet it becomes a few steps that bodies can climb or defend. Van Dyck links those two scales through the column behind Ambrose. The vast building seems to bear down on the small space in which the dispute takes place.

Both principal figures wear splendid clothes. The laurel and armour announce imperial status, while Ambrose's ceremonial dress is equally commanding. The picture asks us to consider competing forms of authority through things we can see: equipment, cloth, height, position and gesture. Religious office has a material splendour of its own.

The cope is particularly arresting because its gold pattern remains readable across large folds. Its curving ornaments draw us into the surface just as its overall shape helps close the entrance. The red cloak has a broader rhythm, travelling from shoulder to thigh and then down towards the foot. One garment expands across the passage; the other accompanies a figure trying to move through it.

Between them, the hands look vulnerable. They are unarmoured, lightly modelled forms surrounded by metal, stone and embroidered cloth. Their meeting gives an intimate scale to a dispute about power. We can follow the action through the reach of an arm and the turn of a wrist.

Working from Rubens

Van Dyck's model was the larger canvas by Peter Paul Rubens , about 1615–16, now in Vienna's Kunsthistorisches Museum. Van Dyck worked in his studio. In the London picture he enlarged the architectural presence and made the imperial group beardless. Changes visible at the surface and through X-ray and infrared examination show that the design developed during painting. ^[1]

The architecture is a useful place to consider what such a change achieves. In the picture before us, stone occupies much of the upper field and presses close behind the bishop's supporters. The emperor's group has arrived at something solid. The resulting compression makes the few inches between the leading bodies feel consequential.

Removing beards also changes the pattern of the heads. The emperor's cheek and jaw are exposed, while the bishop's beard remains a prominent pale shape beneath his face. Across the group, shifts between skin, hair, metal and shadow provide a rhythm of small contrasts. These decisions affect how we locate each speaker and follower in the crowd.

Revisions within a painting are valuable evidence of choices made as work proceeded. They tell us that this composition was being reconsidered. They leave the business arrangement surrounding it unresolved: a changed head or column cannot establish who commissioned the picture or the terms under which it was produced.

The early relationship with Rubens is explored further in Van Dyck's Antwerp years . Here its importance lies in a specific encounter between two painted solutions to the same subject. The London canvas invites attention to the decisions that made this particular gathering feel so tightly contained.

What four paint samples reveal

Raymond White's 1999 study records four samples from NG50. All contained linseed oil, with differences between passages. The mixture from the step's shadow contained heat-bodied oil, pine resin and traces of compounds called lower hopanes. Oil from the golden shoulder trimming of Ambrose's robe was partially heat-bodied; the architectural grey at the upper right was identified as linseed oil. The emperor's red glaze contained partially heat-bodied linseed oil with a little pine resin. ^[3]

“Heat-bodied” means that the oil had been modified by heating. White cautiously associated the lower hopanes in the shadow sample with possible heated asphaltic or bituminous material. These are findings from specified fragments, with a tentative interpretation attached to one of them. They establish neither a single formula for the canvas nor the composition of every dark or red passage. ^[3]

Their locations provide a useful return to looking. The samples came from surfaces that perform very different tasks in the image: a shadow beneath the figures, a gleaming border, cool masonry and the emperor's coloured drapery. Analysis lets us approach the painted object at that small scale, while the eye follows the larger arrangement of light, colour and mass. More about the limits and uses of such evidence appears in Van Dyck's style and technique .

An Antwerp face and an uncertain early journey

The illuminated man second from the right has been proposed as Nicholaes Rockox, an Antwerp alderman; a commission from him is also possible. Both suggestions remain qualified. ^[1]

His face offers an interesting change of emphasis within the crowd. Ambrose turns towards the left, the young attendant faces into the gathering, and several heads are partly submerged in shadow. This man's features are comparatively accessible. His position makes him available to our attention without moving him into the main exchange. If the identification is accepted, an Antwerp contemporary has been placed among the witnesses to an ancient Christian story. The portrait proposal gives that presence a possible name; it does not disclose a patron's instructions.

The early ownership history is similarly qualified: perhaps Rubens's sale in 1640, probably Roger Harenc's in 1764, and apparently Lord Scarborough's collection before Hastings Elwyn. John Julius Angerstein owned it by 1807; the Gallery bought his collection in 1824. ^[1]

Those cautious beginnings matter because the painting's relationship with Rubens can otherwise encourage an overly tidy account of its passage from one collection to another. Its first owner's identity remains less certain than the decisions we can study on its surface.
