Who is the greatest artist of all times? Poussin, Rembrandt, Courbet… no, Koons. Why? Because we can’t stop looking at Koons’ “blue mirrored, hand-blown glass gazing ball” placed in the center of each “old master” painting. Art history can not be re-written but it can be re-layered over and the new “gazing ball” layer makes it more beautiful, more admirable and indeed more collectible.
