Understanding the working method

In 2012, after three years of extensive art-historical research, conservation, and restoration, the Fondation Beyeler completed the greatest conservation project in its history: the scientific examination of Henri Matisse’s Acanthes (1953, 311.7 x 351.8 cm), a masterpiece from his series of large-format “papiers découpés.” Our partner for this project was the international art insurance company Nationale Suisse.

Initial condition

The goal of the project was to conduct art-historical research on the making of Matisse's cut-out, to evaluate the condition of Acanthes and to determine and execute necessary conservation work. Conservators also conducted an intensive technical examination, studied sixty comparable works and reconstructed a dummy “papier découpé” themselves. Contact with experts from national and international collections to discuss similar challenges in conservation and restoration was another important aspect of the project.

One of the major challenges in the conservation and restoration of Acanthes is the complex structure of the image, which consists of several layers and needs to be stabilized. The gouache, papers, pastes, and fabric each underwent different natural aging processes. For example, the unprotected margins showed tears, creases, and stains.

In charge of the project were Markus Gross, chief conservator of paintings at the Fondation Beyeler, Stephan Lohrengel, paper restorer, and curator Ulf Küster. The public was able to view the entire conservation procedure from a show-atelier built especially for that purpose. .

Matisse’s working methods

One of the project’s key findings regarded Henri Matisse's working methods. About half of his 220 cut-outs were mounted on canvas to stabilize them, a job carried out by the Lefebvre-Foinet company. Matisse himself developed and approved this procedure during his lifetime. Many of the operations in the studio were not conducted by Matisse himself, but by assistants working under his supervision. They would paint the papers and affix them to the wall. The essential elements of the work process, however — the cutting and composition — were done by the artist himself. 

Pinholes

The separate paper elements and paper background are full of pinholes as a result of Matisse's working methods. They were made when the forms were pinned to his studio wall. They also provided evidence that this particular piece began and developed from the blue forms, as they have the most pinholes. Before the forms were removed from the wall, the projecting nails were replaced with pins. These were used to fix the forms to the paper background, then a piece of tracing paper was laid on the work in order to draw the forms. The creases in the green forms and the visible charcoal lines were not the result of damage but originated in the studio due to Henri Matisse's working methods and technique.

Good condition of the cut-out

The examinations showed that in comparison to Henri Matisse’s other large-scale “papiers découpés,” Acanthes is in good to very good condition. Only minimal stabilization was needed, and a few weak spots needed to be improved. Though it involves thirteen different layers of paper, paste, canvas, and a stretcher frame, the structure is considered stable. Conservators did not discover any major damage on the image itself. This is due in part to the use of quality materials and the fact that it was well mounted. The work was also protected by glass from an early date. 

New frame

Acanthes is the largest framed picture under glass in the Beyeler Collection [[link]]. The frame lends the structure stability, and the special glass protects the fragile surface from dirt, physical damage, and harmful light radiation. The new framing of the work is intended to accentuate the “reduction of form to the essentials” intended by Matisse. During the extensive search for a solution, conservators worked in close collaboration with the framing specialists and curators of the Fondation Beyeler.
