Amedeo Modigliani is one of the most faked artists. A prolific Modigliani expert, Christian Parisot has written about this artist and his works for four decades. In fact, as the current President of the Modigliani Institute in Rome, Parisot, has been working on Modigliani catalogue raissones, a compilation typically used to weed out real works from fakes. Perhaps Parisot was too familiar with Modigliani's work. In December 2012 he was arrested in connection to an international forgery investigation. Now, he is accused of providing false certificates of authenticity for works appraised at millions of dollars. Another individual identified in connection with the fake Modiglianis is an Italina art dealer Matteo Bignapiano. More details about their dealings are sure to follow.
