An interesting article about possible proof of the only existing Michelangelo bronzes known to exist! This is a great example of how hard it is to prove important examples of art work and antiques.
People often do not understand the extreme importance of provenance and/or factual evidence and/or forensic evidence in authenticating and placing the highest possible values on important antiques and art works. Doing that work is no small process. I am asked all the time to do authentication work, however, people do not understand nor want to pay for that work and expect us to rubber stamp things, which any legitimate art and antiques professional will never do and which far too many un-credentialed appraisers and antique dealers do do. if you want a rubber stamp, look to them, not us, but expect trouble when you want to get your insurance, tax deduction or sell the piece.
Authentication can not be done without doing all of the necessary work, period. The commitment must be made to doing ALL of the necessary work every time. It is not cheep, it generally is a slow process, some times painfully slow, but it can be the difference between an appraisal of hundreds of thousands or even millions of dollars , and a few thousands dollars or even a few hundred dollars. Therefore, in the end, if you truly believe you have the real thing, it is more than worth the costs involved in proving it, but you must commit to doing it right from the beginning and not getting cold feet or trying to cut corners. Otherwise, the client does not believe it is what they say if they do not want to commit to the proper and full process of authentication work and spend the money on it. It is much like investing in the stock market, or gambling, you must study what you want to buy/game you want to play, and commit to the belief you know what you are doing, but know that some times you lose. However, if you do your research and training properly and intelligently, you have a much better chance to back up your belief in what you are doing.
I had a client who had two potentially important Chinese paintings, but they only wanted to go so far in proving their authenticity, which was not enough, and I explained that to them. I explained that more specialists needed to be involved, but they were only willing to allow one, which is not how to do it. You must have a consensus of experts, and the only specialist-expert I was allowed to consult with to give a second opinion, gave results that matched our preliminary results, which were that 1) we need more work to establish factual evidence, 2) the current evidence pointed to the works being very old reproductions, not originals, and so the expert was in agreement with these initial conclusions, which means, we must state the pieces were not originals. In the end, I had to go with the limited proof that they allowed me to establish, which showed the works were not originals. I actually do believed they may be originals, but without the client allowing all the necessary and proper authentication work to be completed, it is NOT possible to prove. And, thus, they had to be declared not to be originals, until after more evidence was compiled, no matter my personal opinion, as my job is to be unbiased, and unfortunately, that is the only unbiased decision that could be made under the limiting circumstances of the clients. The lesson as a client, you need to be willing to commit to the entire process and trust and allow us to do our work. Some times we will break your heart, however, when we prove authenticity, we will bring elation and significant value.
