- Abstract: The collection of Italian paintings at the Museum of Contemporary Art of the University of S~ao Paulo (MAC- USP), Brazil, is very important since it was used to create in 1948 the ¯rst museum about Modern Art in S~ao Paulo, Brazil. One of those paintings is the \Natura Morta", oil on canvas (50.4 x 72.2 cm), produced in 1946 by Mario Mafai. It has another composition on its back of an unknown artist. To help the MAC-USP investigation to understand the pigments used by Mafai and also to compare both compositions to estimate if the back painting has been done at the same period by the same artist, we performed in situ Energy Dispersive X-ray °uorescence (EDXRF) analysis in the two paintings and interpreted the results by running Monte Carlo simulations. The EDXRF is a well-known technique for non-destructive and in situ analysis widely used in Cultural Heritage analysis, while Monte Carlo simulations can help to understand the multilayer structure of an object. Preliminary results indicate the use of Vermilion, Cadmium Red, Zinc White, Lead White, Strontium Yellow and Iron and Chromium based green pigments. Most of the pigments found in the Mafai painting were also identi¯ed in the back composition, suggesting that both were done by the same artist. Stylistic analyses, however, still need to be performed to con¯rm the authorship of the back composition.
