Roverella Altarpiece

A single altarpiece can teach more once it has been broken apart. The Roverella panels, split between museums, force us to read a Renaissance commission as fragments.

Look closer
Oil and tempera on the same support
The work is recorded as oil paint and tempera on wood. That pairing is not a modern restoration quirk; it is part of how the panels were made. Tempera gives a hard, matte surface and sharp edges; oil allows slower blending and deeper darks. On a polyptych meant to be read across several boards, the two media could be used for different tasks — flesh, drapery, metal, sky — without the whole surface having to behave as one.
A polyptych reduced to parts
What survives is not a single continuous picture but a polyptych: a multi-panel altarpiece whose units were always meant to be joined by frame and architecture. One recorded panel measures only 39 by 29 centimetres (11 in). That modest size is a reminder that the object in front of a visitor is a fragment of a larger liturgical machine, not a freestanding easel painting that has simply changed address.
Four addresses, one commission
Panels from the same altarpiece now sit in the National Gallery, the Department of Paintings of the Louvre, Palazzo Colonna, and the San Diego Museum of Art. Looking closely at any one of them means accepting absence: the adjoining saints, the crowning scenes, the carpentry that once locked the sequence together. The scatter is not background noise; it is the condition under which the work is known.
The story
The Roverella Altarpiece is a religious polyptych by Cosimo Tura, with an inception date of 1470. It was painted in oil and tempera on wood. What remains of it is no longer one object in one place. Its panels are divided among the National Gallery, the Louvre Museum, Palazzo Colonna, and the San Diego Museum of Art.
In its own time the work belonged to a clear setting. It was commissioned by the abbot and cardinal Bartolomeo Roverella for the church of San Giorgio fuori le mura in Ferrara, as a memorial to his brother, the bishop Lorenzo Roverella. An altarpiece of this kind was not a private picture. It stood in the public and liturgical life of a church, binding family memory to the rhythms of Mass and feast day. Tura’s panels were part of that furniture of devotion: wood, paint, and structure arranged so that worshippers and clergy could read a sacred story across several fields at once.
The altarpiece did not survive intact. In 1709 it was damaged in an explosion and was moved out of the church. From that point the work’s history is one of separation. The polyptych was dismembered; its panels were treated as independent paintings and entered different collections. A visitor who meets a single panel today meets a piece of a lost whole, cut free from the frame, the adjoining images, and the Ferrarese church interior that once held them together.
The materials still speak of the original ambition. Oil paint and tempera on wood were both in active use in fifteenth-century Italy; combining them on panel allowed Tura a range of surface effects within a single commission. The recorded dimensions of one panel — 39 centimetres (1 ft 3 in) high and 29 centimetres (11 in) wide — underline how much of the original structure is missing from any single museum wall. A polyptych is an argument made in parts. When the parts are hung in London, Paris, Rome, and San Diego, the argument has to be reconstructed from catalogues, measurements, and careful looking rather than from a single continuous surface.
What can still be said with confidence is limited and concrete. The creator is Cosimo Tura. The genre is religious art. The form is a polyptych. The inception date is 1470. The support is wood; the media are oil and tempera. The present homes of the panels are known. Beyond that, the story of the altarpiece is the story of damage, removal, and dispersal — and of how a Renaissance church commission continues to exist only as a set of separated survivors.
Why it mattered then
In Ferrara around 1470, a polyptych of this kind did several jobs at once. It furnished a church altar; it fixed a family’s remembrance of a dead bishop in a permanent public form; and it displayed the skill of a leading local painter in the media and format the liturgy required. Commissioned by Bartolomeo Roverella for San Giorgio fuori le mura, the work tied cardinal and bishop, living donor and deceased brother, into the daily life of the church. Religious art on panel was not illustration hung for private pleasure. It was part of how a community saw itself before God: saints, narrative, and donor memory arranged so that the eye could move across the structure during worship. Tura’s use of oil and tempera on wood belonged to that practical and devotional world. The finished polyptych mattered because it completed a commission, filled a sacred space, and made one family’s piety visible to everyone who entered the church.
Why it matters now
The Roverella Altarpiece matters now precisely because it no longer stands as one work. Its panels, split among the National Gallery, the Louvre, Palazzo Colonna, and the San Diego Museum of Art, force a modern viewer to think about incompleteness as a historical fact rather than a temporary inconvenience. Renaissance altarpieces often survive as fragments; this one makes that pattern explicit. Studying it means tracking measurements, materials, and locations across institutions, and accepting that any single panel is only a portion of a lost liturgical whole. The work also keeps Cosimo Tura’s name and the Ferrarese religious commission of 1470 in view inside major public collections. It still matters as evidence of how sacred furniture was made, how violence and later taste can dismantle it, and how museums inherit the pieces.
The surprising detail
The altarpiece’s present life began with an explosion. In 1709 the work was damaged by a blast, removed from San Giorgio fuori le mura, and later dismembered. What had been a single polyptych in one Ferrarese church became a set of separate panels that travelled into different collections. The scatter is extreme enough to be easy to miss: a visitor in London, Paris, Rome, or San Diego may see a Tura panel without realising its companions hang continents or countries away. The object most people meet is therefore not the altarpiece as commissioned in 1470, but a survivor of demolition by accident and by later collecting.
What is disputed
The original order, framing, and full iconographic programme of the polyptych cannot be recovered from the surviving panels alone. Reconstructions differ, and the precise appearance of the altarpiece in San Giorgio fuori le mura before the 1709 damage remains partly conjectural. The inception date is given as 1470; some accounts extend the campaign into the following years, but that wider span is not fixed in the core record used here.
How it got here
After damage in an explosion in 1709, the altarpiece was removed from San Giorgio fuori le mura in Ferrara and later dismembered. Its panels entered separate collections and are now divided among the National Gallery, the Louvre Museum (Department of Paintings), Palazzo Colonna, and the San Diego Museum of Art. The paths by which individual panels reached each institution are not set out in the facts used for this lesson; what is certain is the present split and the loss of the original church setting.
Remember this
A 1470 polyptych by Cosimo Tura, painted in oil and tempera on wood, now exists only as panels divided among four collections.
Test yourself
Why does knowing that the Roverella Altarpiece is a polyptych change how you should look at any single panel in a museum?
Because a polyptych was designed as a set of related panels joined by structure and meaning, not as freestanding pictures. A lone panel — even one only 39 by 29 centimetres (11 in) — is a fragment of a larger liturgical arrangement. Its composition, scale, and subject were meant to be read beside neighbouring fields that are now in other collections. Looking well means holding that absence in mind rather than treating the panel as a complete easel painting that happens to have a complicated address book.
