New Map

A painting attributed to Paul Cezanne is under scrutiny for its authenticity, involving a team of experts analyzing various pieces of evidence. Dr. Simpkins and Dr. Montoya provide supporting evidence, citing fluorescence data, pigment compositions, and brushwork similarities to known Cezanne works.

New Map

Paul Cezanne's painting under scrutiny

Conclusion: there is no clear conclusion

Dr. Andersen (scientist) counter evidence

there is underdrawing and Cezanne never did underdrawings
pigment mix of yellow areas wasn't used until 1927 after Cezanne's death
used infrared spectroscopy

Dr. Pruschy (scientist) counter evidence

polyene absorbtion 0.6 instead 0.15 --> not 100 years old
used ultraviolet spectrum of a paint chip

Dr. Simpkins (scientist) pro evidence

the fluorescence data support attribution to Cézanne
trees and rooftop similiar to Cezanna painting Gardanne

Dr. Montoya (scientist) pro evidence

however, can be faked by a material scientist
compositions of pigments available during Cézanne's time
used x-ray fluorescence

Dr. Marden (historian) pro evidence

characteristic of his constructivist phase late 1880s
same brushwork
similiar to a Cezanne at the Barnes foundation

4 scientists from spectrotech, Edgar, Dr. Marden and Mr. Wandless investigated

Is fake or not?
