Medicine, painted by Gustav Klimt for the University of Vienna ceiling, was destroyed by retreating Nazi troops in 1945 alongside two other paintings from the same series, Philosophy and Jurisprudence. At the time, the allegorical depiction of Hygeia, Greek goddess of health and hygiene, as a figure of life and death was a radical departure from typical representations. The artist was attacked for this representation and for the nudity and excess of his paintings, which were never displayed in the university. However, although the paintings themselves were destroyed, a number of preparatory sketches for Medicine as well as one good black-and-white image survive.
Preparatory work for the recreation
The surviving black-and-white image, printed onto a 430x300cm canvas prepped with gesso, guided the re-creation of the painting. Using this image, it was also possible to reconstruct the depth of tone of the colours in the original painting. To obtain the tones themselves, Klimt’s colour palette was studied together with surviving colour sketches for Medicine.
The team at Factum worked outwards from the centre of the painting, building up a first black-and-white preparatory layer with an oil-paint airbrush to cover up the pixelation of the photo. The painting’s vibrant colours were reproduced using both the airbrush and more traditional oil painting techniques. The airbrush was used in areas where transparencies or softer tones were required, as well as to create looser, flowing strokes. The paintbrush was used for details, or where the brushstrokes had to be smaller, such as in the pale background. It was particularly challenging to make sure that the figures did not appear disjointed from their surroundings in the vast canvas and a lot of effort was put into building up shadows and light sources.
Recreating the morphology of Klimt’s brushstrokes
The physical re-creation of Medicine was photographed at high-resolution. In Photoshop, this image was juxtaposed against the surviving black-and-white photograph. Despite the low quality of this second image, Klimt’s confident brushstrokes were clearly visible. In our painted version, the brushstrokes were slightly longer and there were a number of small errors. These were warped in Photoshop to conform more closely to the original. The result is a digital image that has the powerful colours of the now-vanished Klimt painting together with the true morphology of Klimt’s brushstrokes.
Klimt’s signature was clearly visible on the black-and-white image. When the two images – black-and-white together with our recreation – were seen together, Klimt’s signature was found to fit perfectly onto ours. The signature from the ‘original’ was therefore incorporated into the final digital version, making the signature in our final re-creation closely related to Klimt’s original. Then, the colour digital image was printed onto canvas, ready for gilding.
Gilding and finishing ‘Medicine’
Like many of Klimt’s works, Medicine included gold leaf; originally gilded areas were identified by studying the black-and-white image. These areas were left blank when painting the re-creation. Based once again on clear evidence from the image, paste was applied onto some of these areas in order to give them volume.
Factum’s gilders used a traditional oil-based size gilding technique to apply 22-carat gold leaf. In this process, an oil and solvent-based mixture is applied evenly with a brush onto the surface. The mixture is allowed to set for a number of hours, after which the very thin leaf can be carefully laid onto the surface. Once dry, the gold is polished with a soft cloth.
In the case of Medicine, small details were finished using oil paint over the gold leaf before varnishing the painting.
