Some points to bear in mind, said by him:
- He said that he viewed and carefully examined in person all the works listed.
- He named his work as a "catalogue raisonné" of Modigliani's production.
- He made at least 5 corrections to his catalogue, the last published in 1972 after his death.
- He used (or said that he did) all the reliable sources and updated frequently.
- If a work by Modigliani is not in Ceroni its value is zero for Sotheby's or Christie's.
- Ceroni was not an art historian he was a banker and an appraiser for the art auction biz.
- After a simple analysis of his work:
- His catalogue can not be called "raisonné", it presents enormous gaps in dating, medium, titles, owners, works, etc.
A catalogue raisonné needs to be absolutely exact, exhaustive and complete.
With this statement, Ceroni´s work should be called a "paintings collection," a good one in comparison with others on Modi, but absolutely not a Catalogue Raisonné, and this is why:
He could not have seen all the works in person since there are totally obvious mistakes.
Works painted both sides, only seen one side, enormous mistakes in supports, "oil on canvas" when it's wood or cardboard, wrong measurements in many works, definitively not a reliable or trustworthy source for cataloguing.
His work was totally out of date in locations and works at the time of printing.
In his last edition he didn't change many of the owners, measurements or mediums when many were totally accessible at that time .
He included several fakes in his catalogue that have silently vanished.
Discover them for yourself...
His dating lacks any explanation and is totally unuseable, for the many mistakes it presents.
It is impossible to read the art evolution in Modigliani because works that come from the same year (the same painting session) are placed in different years.
He omitted some of the most glorious works by the Livorno master.
Remember, it is a "catalogue raisonné" and that means he must include "all" Modi's production. (not our problem how he solves things like lost or whatever, it is raisonné or not?).
I use as base " Modigliani the pictorial works", introduction by L. Piccioni. / Noguer Edit. Barcelona, 1972-77 (known as Rizzoli 1970).
