The Tympanum with Two Histories
The Church of Saint-Pierre in Valeux has a 12th-century stone tympanum over its west portal, carved with the Last Judgment. In 1889 a local sculptor re-carved several faces, added a scroll with a French inscription, and applied a polychrome scheme of blue, red, and gold. The parish wants to remove the 19th-century paint and “restore” the stone to its medieval appearance before a heritage festival. A conservation report finds that the 1889 paint is oil-based and has penetrated the stone; removing it would require abrasive methods and would damage original tool marks. The report also notes that the 1889 recarving is itself historically significant because it documents a Gothic Revival intervention. The parish council has €30,000 and three months. The bishop supports the parish; the regional heritage authority must approve any treatment. The conservator recommends stabilization, cleaning only loose dirt, and no removal of polychromy. The parish argues that the colors look “Victorian” and distract from the Romanesque carving.
1. Recommend whether to remove the 1889 polychromy. Justify with conservation principles and historical reasoning.

The 1889 polychromy should not be removed on the present evidence. Conservation ethics favor minimal intervention, reversibility, and respect for the object’s full history, not only its medieval phase. The report says the oil paint has penetrated the stone and that abrasive removal would damage original tool marks-an irreversible loss. The 1889 recarving and paint are also historically significant: they document a Gothic Revival restoration and the taste of that period. Removing them would create a false impression of a pure Romanesque surface and would destroy evidence. The parish’s objection that the colors look “Victorian” is an aesthetic judgment, not a conservation necessity. The appropriate treatment is stabilization: clean loose dirt, consolidate flaking paint, control moisture, and document the surface. If the paint is actively causing salt decay, a conservation scientist should test whether a controlled treatment can reduce the damage without removing all polychromy. The regional heritage authority should approve any intervention.
2. Propose an interpretive solution for the heritage festival that addresses the parish’s concerns.

For the heritage festival, the parish can interpret the tympanum as a layered object rather than a failed medieval one. A temporary panel could show a large photograph of the 1889 state, a raking-light photograph of the medieval tool marks, and a short text: “The stone was recarved and painted in 1889. We are preserving that history, not erasing it.” A digital projection could show a reconstruction of the probable medieval appearance on a screen beside the portal, clearly labeled as a hypothesis. The parish could invite a conservator to give a 20-minute talk after Mass and train a volunteer to explain why the paint is being kept. Lighting can be adjusted to reduce the “Victorian” glare and emphasize the carving. A children’s activity could trace the iconography of the Last Judgment. These measures address the parish’s desire for a festival focus without sacrificing the object’s integrity.
3. What would justify removing the paint, and what safeguards would be required?
Read the worked answer
Removal would be justifiable only if the 1889 paint were proven to be actively causing irreversible stone decay-for example, if its oil medium were trapping salts that spall the surface-and if a tested, minimal method could remove it without touching original tool marks. Even then, the museum-standard safeguards would apply: a written treatment proposal, cleaning tests on inconspicuous areas, microscopic monitoring, photographic documentation before, during, and after, and approval by the regional heritage authority. The work should be done by a qualified stone conservator, not a sculptor or builder. Any removal should be partial and reversible where possible, and samples of the paint should be retained for future study. The parish should be told in advance what evidence would be lost. Given the current report, those conditions are not met, so removal is not justified.
