Mode
Congregational church for a preaching order; a single vaulted nave with linked side chapels, the type set for the Catholic world
Mythos
The way from door to altar as the soul’s way to the sacrament; the cross drawn in as one body; the roof opened as heaven; the founder and the missionary kept as relics at the arms of the cross
Phase
First stone 26 June 1568; Vignola to his death in 1573; della Porta’s front in place of Vignola’s and the dome; consecrated 1584; Gaulli’s vault 1672 to 1679; Pozzo’s altar of Ignatius in the 1690s; the high altar and marble revetment in the nineteenth century
Presentation
One wide barrel-vaulted nave without aisles, lit by lunettes; three linked chapels a side; transepts within the line of the chapels; a dome on a drum and a short apse; a front of two storeys joined by scrolls under a pediment
Register
Grave and measured in the body, saturated and theatrical in the vault and the transept altars; a rising approach to light at the crossing
Scale
One order, one patron’s name, one room for a congregation; a Church at once reforming and triumphant, and its missions to the world
Governing Proposition
A new order founded to preach builds its mother church in Rome as one room: no aisles, no columns between the people and the altar, the chapels pushed to the walls, so that a congregation is one body in sight of the sacrament and in earshot of the pulpit. A century later painters and sculptors open its roof onto heaven and set the order’s founder and its missionary at the two arms of the cross. The wager of the church is that a known type, made shallower, brighter at the crossing and fitted to a liturgy, can become the standard of a whole communion, and that three campaigns laid on one body can still converge on one altar.
Act II · The Essay
Movement I
The church is the Chiesa del Santissimo Nome di Gesù all’Argentina, the mother church of the Society of Jesus, on the Piazza del Gesù in Rome. Its patron was Cardinal Alessandro Farnese. The first stone was laid on 26 June 1568, and Jacopo Barozzi da Vignola, who designed the plan and the body of the church, directed the work from that day to his death in 1573. Giacomo della Porta completed it, built the dome, and built the front to his own design in place of the one Vignola had drawn, which is known from an engraving of 1573. The church was consecrated in 1584.
The order was new and its purpose was preaching. A church for such an order has to gather a congregation where everyone can see the altar and hear the pulpit, and the building answers that need before any other. The answer is one room. There are no aisles and no rows of columns between the people and the sacrament; the chapels are pushed to the walls; the whole is a single vaulted space ending in light at the crossing. That decision governs the plan, the structure and the use, and it was Vignola’s.
What is scored here is the church as it stands, its later decoration weighed. Everything built and fitted into it in its life as that church is part of the one work, and is credited or charged to the work, not to Vignola or della Porta: Gaulli’s vault, dome and apse with Raggi’s stucco; Pozzo’s altar of Ignatius; the altar of Xavier; the side chapels; and the nineteenth-century high altar and marble revetment. The Jesuit house beside it, the rooms of Ignatius and the piazza are context. The church that stands is therefore three campaigns on one body: the sixteenth century’s plan, the seventeenth’s heaven, the nineteenth’s marble.
Movement II
The plan is a Latin cross folded into a near rectangle. One wide nave runs under a barrel vault, without aisles. Three chapels open off it on each side, and low passages link each chapel to the next, so that people can move along the edge of the church without crossing the nave. The transepts do not project beyond the line of the chapels. Over the crossing a dome stands on a drum, and beyond it a short choir closes in an apse. The nave is lit by lunette windows cut into the vault above the chapel cornice.
The structure is the plan read another way. The wide vault rests on a thick wall, and the chapels are hollowed out of that wall, so that they are its buttresses: what gives the side devotions their rooms is what keeps the vault standing. The transepts drawn inside the rectangle let the crossing gather light without breaking the room into arms. The dome lights the altar end, where the eye is meant to arrive. The span is wide for its date but not new, and the engineering extends nothing; its command is of proportion, of nave to chapel and of light to axis.
The type was not invented here. Alberti’s Sant’Andrea at Mantua (8.5), begun in 1472, had already given a single barrel-vaulted nave with chapels in place of aisles. The Gesù made that type shallower and more open, lowered and linked the chapels, pulled in the transepts and concentrated the light at the crossing, and fitted it to the needs of a new order. The departure is real and measured, a synthesis of a known type, and it holds The Swerve to 8.3. Its consequence was another matter: Sant’Andrea did not become the type until the Gesù made it one.
Movement III
A century after the first stone the roof was opened. Giovanni Battista Gaulli painted the nave vault, the Triumph of the Name of Jesus, in 1672 to 1679, with Antonio Raggi’s stucco, and painted the dome and the apse. In the vault the Name shines in light at the centre of a sky. Clouds and bodies spill across the gilt frame onto the stucco and cast painted shadows on the real vault, so that the boundary of the church and the boundary of heaven become one line and the roof seems to give way.
The figures of the damned fall out of the painted frame toward the people below. Judgment is staged over a congregation that is being preached to, and the room the sixteenth century built for seeing and hearing in common becomes a theatre in which the doctrine is enacted overhead. The perspective was calculated for the nave: the vault is made to be looked up at by someone walking toward the altar, and the walk down the nave becomes a rising approach under the opened sky to the light of the crossing, where the dome and apse carry the painting on.
The vault is a departure in ceiling painting, painting and stucco fused and the frame broken, with Bernini’s circle behind it. It belongs to the church’s own life and is scored as the church’s. It lifts The Sublime to 8.8, and it carries much of The Archetypal Deep: the vault is heaven opened by breaking the architecture, not a picture set into a ceiling. It also charges. The richness of the whole can deaden as well as lift, and the chapels below the vault are dim and of uneven quality.
Movement IV
At the two arms of the cross stand the order’s founder and its missionary. In the left transept is Andrea Pozzo’s altar of Saint Ignatius, of the 1690s: columns of lapis, a globe, and the statue of the saint revealed behind a lowered painting. Ignatius’s tomb lies under it. In the right transept the altar of Saint Francis Xavier holds the relic of his forearm. The building holds the bodies of its saints as a shrine does, and the cross of the plan becomes the Society’s account of itself: its founder at one arm, its mission to the Indies at the other, the arm of the Church in the world.
Pozzo’s altar is grandeur of the treasury kind, overwhelming by material and by stagecraft, assembled of rare stone, metal and sculpture by many hands under his direction, and its unveiling makes the transept an event and not a fitting. It is also larger and richer than the plan requires. Here the law of the axis bends: Pozzo’s altar overpowers the arm that holds it. The silver statue of Ignatius that once stood in it was melted and replaced, the principal loss to the fabric, charged lightly as a part of one altar.
The nineteenth century added the high altar and laid marble revetment over the nave. It is accomplished but routine, and it adds weight to the pilasters without adding sense. So three physics lie one on another: Vignola’s restrained body, a Baroque surface and a nineteenth-century skin. The passage from one to the next is visible on the pilasters and in the transepts. One law still governs, the convergence of everything on the altar and, above it, on the Name; the seams hold The Inner Law to 8.3.
Movement V
Della Porta’s front is two storeys of pilasters, the upper narrower and joined to the lower by great scrolls, under a pediment over the whole, with a segmental pediment over the door set within a triangular one. The scrolls take up Alberti’s precedent at Santa Maria Novella. The centre is heightened over the door, so that the front is the threshold of the convergence the interior completes. It is dignified rather than elevating, and crowded: its storeys are not fully resolved into one plane, and its doubled pediments and close pilasters could be thinned without loss.
It fixed a type all the same. Sant’Ignazio in Rome, Saint Michael in Munich, Saints Peter and Paul in Kraków, and churches across Europe, the Americas and Asia followed the plan or the front or both, and the scrolled front of two storeys became the commonest church front of the Catholic world for two centuries. The reach was carried by an order’s network as much as by the building, but the plan, the front and the vault were copied as the Gesù’s. Whether there was a “Jesuit style” at all is an old question and still argued, and the Gesù has been read as proof of it and as disproof.
Among its neighbours on the desk, Palladio’s Il Redentore (8.6) is the purer building of the same decades and the Gesù the more consequential; St Peter’s Basilica (9.0), Borromini’s San Carlo alle Quattro Fontane (9.0) and Sant’Ivo alla Sapienza (8.8), and Bernini’s Ecstasy of Saint Teresa (8.9) stand above it on the swerve or on the making. The church has stood in its own use since 1584, through the suppression of the order in 1773 and its restoration in 1814, and is in daily worship. Its form is whole, and its standing of 8.6 rests on that survival, on its reach and on a single room that let a congregation see and hear.
Act III · The Twelve
Judged on plan, structure and use. The governing decision resists the subtractive test: take away the aisles and the congregation is one body before one altar and in earshot of one pulpit, which is what a church for a preaching order is for. The chapels are pushed to the edge and linked so that private devotion never crosses the nave; the transepts are drawn back inside the rectangle so that the crossing gathers light without breaking the room. What yields is in the later work: the two transept altars, Pozzo’s above all, are larger and richer than the plan requires, the nineteenth-century marble adds weight without sense, and the front’s doubled pediments and crowded pilasters could be thinned.
Score: 8.4 / 10
What can be stated and holds: the Catholic reform of the later sixteenth century made worship a matter of seeing and hearing in common, the Mass visible to every person in the room and the sermon audible to all, and the Gesù is that claim built. A nave without aisles discloses a church that is an auditorium and a theatre of the sacrament at once. The decoration states the rest: judgment staged above a congregation being preached to, and the order’s founder and its missionary set at the two arms of the cross. Held at the gate and not above it because much of the disclosure is institutional, a doctrine of the Church triumphant rather than a human condition newly uncovered.
Score: 8.6 / 10
Height is high and comes in more than one place. The summit is the nave vault: Gaulli’s sky, its clouds and bodies spilling across the gilt frame onto Raggi’s stucco and casting painted shadows on the real vault, so that the roof seems to give way. The dome and apse carry it toward the altar. The altar of Ignatius, with its columns of lapis, its globe and the statue revealed behind a lowered painting, overwhelms by material and stagecraft. The walk down the nave is a rising approach to the light of the crossing. It falls at the edges: the front is dignified rather than elevating, the chapels are dim and uneven, and the richness of the whole can weigh as well as lift.
Score: 8.8 / 10
The archetype is built into plan and structure. The axis from door to altar is the soul’s way to the sacrament, made the only direction the room allows. The cross is the plan, drawn in so close that it is felt as one body rather than as arms. The vault is heaven opened, not by a picture set in a ceiling but by a painting that breaks the architecture, so that the edge of the church and the edge of the sky are one line. The founder lies in his altar and the missionary’s arm is kept in the other, as a shrine holds its saints. Held at the gate because much of the myth rides on the decoration, staged more than built in stone, and the plan’s myth is that of every longitudinal church.
Score: 8.6 / 10
The inheritance was the aisled basilica, which Roman churches still followed, and, decisively, Alberti’s Sant’Andrea at Mantua, begun in 1472, which had already given a single barrel-vaulted nave with chapels in place of aisles. The departure is real but measured: the Albertian type made shallower and more open, the chapels lowered and linked, the transepts pulled in, the light gathered at the crossing, the whole fitted to a new order’s needs and made a standard. The stake was moderate: no one risked a tested path. The larger swerve is in the later work, Gaulli’s fusion of painting and stucco with the frame broken and Pozzo’s machinery of revelation. Held below the gate because the building’s own turn is a synthesis of a known type.
Score: 8.3 / 10
Substitute another form and the worship is lived differently. In an aisled church half the people see the altar between columns and the preacher speaks to a room of compartments; here they are one assembly in one space, and the order’s liturgy, the preaching, the frequent Mass, confession in the chapels and devotion at the founder’s tomb, each has its place without crossing another. The linked chapels let side devotion go on while the nave is in use; the dome’s light makes the approach a movement toward brightness. The vault is made to be looked up at from the nave, and the unveiling of Ignatius makes the transept an event. Held below the top because the form’s knowledge is Alberti’s as much as Vignola’s.
Score: 8.9 / 10
Evidence over promise: some four and a half centuries of return. The church has been read as the type of the Counter-Reformation church; as the proof or disproof of a “Jesuit style”, a debate that is old and still argued; as Vignola’s measured classicism against della Porta’s livelier front; as the place where the Baroque ceiling reached its fullest illusion; as a study of patronage, the Farnese name on a Jesuit front; and as a record of the order’s devotion in fabric. What the order wanted from its architecture, and how far the Gesù is a model rather than a coincidence of builders, stays open. Held below the summit because the yield is more historical and typological than inexhaustible in the room: the plan, once understood, is clear.
Score: 8.4 / 10
The field is the Catholic church of the later sixteenth and seventeenth centuries, in Rome, Europe and the mission lands. The intrinsic force is a synthesis rather than a first stroke: the single-nave church existed at Mantua, and the Gesù made it the answer to a new liturgical demand and gave it canonical proportions, chapels and light; della Porta’s front, two orders joined by scrolls on Alberti’s precedent at Santa Maria Novella, fixed a type; Gaulli’s vault reorganised ceiling painting. Achieved reach is scored with intrinsic force: Sant’Ignazio in Rome, Saint Michael in Munich, Saints Peter and Paul in Kraków, and churches across Europe, the Americas and Asia followed the plan or the front or both, and the scrolled front of two storeys became the commonest church front of the Catholic world for two centuries. Held below the top because the reach was carried by an order’s network as much as by the building.
Score: 9.1 / 10
Weighed on form, use and fabric. The form is whole: Vignola’s plan and body, della Porta’s front and dome and the later decoration stand, and the type has outlived the conditions that made it, a reforming council’s demands and a new order’s first generation. The use is continuous in its own purpose: the Society’s church in Rome since 1584, through the order’s suppression in 1773 and its restoration in 1814, and still in daily worship. The fabric is largely the builders’ and decorators’. The principal loss, the silver statue of Ignatius, melted and replaced, is a part of one altar and is charged lightly. Some four hundred and forty years with form whole and use unbroken stand in the upper band; its presence is wide in Rome and among historians, narrower in general fame.
Score: 9.3 / 10
Judged as command of building, structure included. Vignola’s command is of the first rank and load-bearing: the proportion of nave to chapel; the wide vault carried on a thick wall hollowed by the chapels, so that the chapels are its buttresses; the lunettes cut into the vault for light; the crossing resolved without a projecting transept. The engineering extends nothing: the span is wide for its date but not new. The decoration is made at the height of its arts: Gaulli and Raggi’s fusion of painted and modelled figures, the vault’s perspective calculated for the nave, and the altar of Ignatius assembled of rare stone, metal and sculpture by many hands under Pozzo. The costs: della Porta’s front is crowded, its storeys not fully resolved into one plane, and the nineteenth-century revetment is accomplished but routine.
Score: 8.8 / 10
Take the two most distant elements: the sober grey pilasters of the front and the gilded sky of the nave vault with the damned falling from it. One law governs both, the law of the axis: everything in the church is placed and scaled to converge on the altar and, above it, on the Name, and the front is the threshold of that convergence, its centre heightened over the door. The chapels, the transept altars and the dome keep the same symmetry. What bends the law is time: Vignola’s restrained body, a seventeenth-century Baroque surface and a nineteenth-century skin of marble are three physics laid one on another, and the seams show on the pilasters and in the transepts, where Pozzo’s altar overpowers the arm that holds it. The range is wide and mostly held.
Score: 8.3 / 10
Orders held: the sacred, in sacrament, preaching and relic; the Church as institution and the new order as its instrument; the state and the great family, in the patron’s name on the front and his money in the fabric; the city, the church set on a main street of papal Rome; history and the world, in Xavier’s missions at one arm and the globe over Ignatius at the other; death and judgment, in the tombs and on the vault; and the congregation, the ordinary worshipper given a place to see and hear. The plan and the axis integrate them. What holds the axis lowest of the twelve: the household, labour and the natural order are absent except as the world to be converted, and consciousness is addressed as a soul to be moved rather than held in its own right.

Strongest Dimensions
The Imperishable at 9.3, Pressure on Tradition at 9.1 and The Living Form at 8.9. Some four hundred and forty years with form whole and use unbroken, through the order’s suppression and restoration; a plan and a front copied across the Catholic world, the scrolled front of two storeys the commonest church front of two centuries; and a single room in which a congregation is one assembly before the altar and the pulpit, its chapels and transepts each giving the liturgy its place.
Limiting Dimension
The Encompassed at 8.1: the sacred, the Church and its order, the state and the great family, the city, the missions, death and judgment and the congregation are held on one axis, while the household, labour and the natural order are absent except as a world to be converted. Below the rest, The Swerve at 8.3 and The Inner Law at 8.3: the building’s own turn refines Alberti’s type rather than breaking from it, and three campaigns on one body leave their seams on the pilasters and in the transepts. The facts are two: the Gesù is a synthesis made a standard, and it is a church whose world is the Church’s.
The Necessity Cap clears at 8.4 against a threshold of 7.5. The Coherence Floor clears with room: The Living Form at 8.9, The Made at 8.8, The Inner Law at 8.3, each against 7.0. The Epochal Gate is unmet: The Imperishable at 9.3, Pressure on Tradition at 9.1, The Unconcealment at 8.6 and The Archetypal Deep at 8.6 clear the bar of 8.5, but The Swerve at 8.3 falls short by two tenths. The Universal Minimum is met (no axis but The Encompassed falls below 8.3, against 7.5) and The Encompassed, which is exempted, clears its own floor of 6.0 at 8.1.
Basis · a reading from knowledge of the church as it stands in 2026 and of its documented plan, structure, decoration and history. No plan, image or written source on the building was consulted. Nothing is quoted: no inscription or contemporary statement on the church is held word for word. The work scored is the church as it stands, its later decoration weighed: Vignola’s plan and body, begun on 26 June 1568 and directed by him to his death in 1573; della Porta’s completion, his front, built to his own design in place of Vignola’s, and his dome; and everything built and fitted into the church in its life as that church, among it Gaulli’s frescoes of the nave vault, dome and apse with Raggi’s stucco, the vault of 1672 to 1679, Pozzo’s altar of Ignatius of the 1690s, the altar of Xavier, the side chapels, and the nineteenth-century high altar and marble revetment of the nave. All of it is one work and is credited or charged to the work and not to Vignola or della Porta on every axis: the transept altars and the nineteenth-century marble are charged under The Inevitable and The Inner Law, and the vault is credited under The Sublime and The Archetypal Deep. Vignola’s rejected design for the front, known from an engraving of 1573, is not part of the work. The silver statue of Ignatius, lost and replaced, is weighed under The Imperishable alone. The Jesuit house beside the church, the rooms of Ignatius with Pozzo’s painted corridor, and the piazza are context and earn nothing. Facts that could not be verified are not given: the inscription on the front and its date, the day of the consecration, the patron’s instructions to Vignola on the vault and the order’s objection to it, the names of the orders on the front, the dimensions of the church, the maker and date of the nineteenth-century work, the date at which the silver statue was melted, and whether the unveiling of Ignatius is still performed.
