Is Cezanne's painting a real or a fake?

Dr. Simpkins (Using long and short UV excitation wave)

- The fluorescence of certain areas resemble the ones found in another painting of Cezanne called "Gardanne" - Pigments were used in the same studio by the same artist

Real

Dr. Montoya (Using X-ray fluorescence)

- The pigments tested were used in Cezanne's life span - The absence of some elements contained in certain pigments reinforces its originality as they were still unknown in Cezanne's period of time

Dr. Anderson (Using IR spectroscopy)

- Although the brushwork applied was charactiristic of Cezanne's early period, the pigments used in the painting weren't widely known known at the time - The binder is based on animal glue which was used widely until the 1940s - There's an underdrawing of a male figure. Cezanne wasn't known for making underdrawings

Dr. Pruschy (Using UV spectrum)

- Each layer of the painting was analysed by UV spectrography and produced nearly identical absorption spectra - The painting shows an absorbance of 0.6 which suggests that it's not likely to go all the way back to a 100 years old

Fake

Art Historians

- The painting is unsigned like most of Cezanne's work. - The painting has many of the same visual elements. - Very characteristic of his contructivist phase in the late 1880s - The brush work is indistinguishable from other pintings of his in that period

Real
