This Research Note proposes that modern art painters make their best works at the optimal moment in their lives, a moment that could then be associated with the Divine proportion (the Fibonacci phi). An analysis of 189 highest-priced works by as many modern art painters, comparing the moment of creation with their life span of these artists, yielded the remarkable result that the estimated fraction is 0.6198, which indeed is only 0.0018 away from the divine fraction.
