Marc Restellini Publishes Six-Volume Modigliani Catalogue Raisonné After Three Decades of Disputes

Marc Restellini has published a six-volume catalogue raisonné of Amedeo Modigliani’s oil paintings after nearly three decades of work, and the release is already a structural event for the market, not just a scholarly milestone. The project expands the recognized corpus with around 100 newly authenticated works while excluding 15 paintings where evidence did not meet the threshold for inclusion. In a field where attribution can shift value by tens of millions, those decisions carry immediate consequences for collectors, lenders, and insurers.

The stated methodology is deliberately forensic. Restellini’s team combines documentary archives, stylistic comparison, and scientific testing, including imaging and material analysis, then evaluates results against benchmark works linked to historically grounded collections. That process model is central to the publication’s claim. It is not presenting connoisseur preference as verdict. It is presenting evidence hierarchy as verdict, then documenting how each conclusion was reached.

That distinction matters because Modigliani has long been one of the most contested terrain in modern art authentication. The artist’s short life, fragmented records, and high market demand created ideal conditions for counterfeit circulation across decades. Meanwhile, the market often relied on legacy frameworks that remained authoritative in practice even when incomplete. The new set challenges that inertia by forcing stakeholders to revisit assumptions that have been operationalized in catalog entries, sale-room notes, and private transaction files.

The financial backdrop explains the pressure. Major Modigliani works have traded at the top of the auction market through Christie’s and Sotheby’s, and those valuations influence lending, collateral, and institutional planning well beyond single sales. A revised corpus changes the risk model for everyone touching the category, from private banks to museum boards. It also increases pressure on intermediaries who previously accepted weak provenance packages under inherited expert consensus.

Publication conditions add another layer. The project survived extended legal conflict over archive access and publication rights, including disputes with the Wildenstein Plattner Institute. That history reveals the core issue: catalogue raisonnés are not neutral containers. They are governance tools that determine who controls historical legitimacy and, by extension, economic outcomes. The more transparent the method, the harder it is for authority to hide behind personality.

For museums, the practical implications begin now. Registrars and curators will need to cross-check existing labels, loan files, and wall texts against the new entries. Some institutions may discover that legacy attributions once treated as stable now require qualification. Others may find that works long considered peripheral can be repositioned with stronger evidentiary support. Either way, collections work will become more labor-intensive in the short term and more defensible in the long term.

The project’s next phase is public-facing. Restellini’s announced collaboration with Pace Gallery, including a New York exhibition and symposium, will move debate from private advisories into institutional space where methodology can be contested openly. That is healthy for the field. Authentication practice improves when arguments are inspectable, not when they circulate as opaque authority inside closed transactions.

The headline is straightforward. This catalogue does not end Modigliani disputes, but it raises the evidentiary floor and narrows the room for casual attribution. In a category defined by scarcity, prestige, and forgery risk, that shift is significant. Stakeholders who adapt quickly will have better data and lower legal exposure. Stakeholders who do not will keep paying for ambiguity that no longer looks defensible.
