It took the Metropolitan Museum of Art nearly 50 years to wake up to Pablo Picasso. It didn't own one of his paintings until 1946, when Gertrude Stein bequeathed that indomitable quasi-Cubistic picture of herself - a portrait of the writer as a sumo Buddha - to the Met, principally because she disliked the Museum of Modern Art.

Early-twentieth-century abstraction is art's version of Einstein's Theory of Relativity. It's the idea that changed everything everywhere: quickly, decisively, for good.

Many museums are drawing audiences with art that is ostensibly more entertaining than stuff that just sits and invites contemplation. Interactivity, gizmos, eating, hanging out, things that make noise - all are now the norm, often edging out much else.

Jeffrey Deitch is the Jeff Koons of art dealers. Not because he's the biggest, best, or the richest of his kind. But because in some ways he's the weirdest (which is saying a lot when you're talking about the wonderful, wicked, lovable, and annoying creatures known as art dealers).

Batty as it sounds, subject and style may choose artists, through some unfathomable cosmic means. How else to explain that even artists who enjoy what they do can be perplexed or even horrified that they're doing it?

Galleries began growing in both number and size in the late seventies, when artists who worked in lofts wanted to exhibit their work in spaces similar to the ones the art was made in.

The price of a work of art has nothing to do with what the work of art is, can do, or is worth on an existential, alchemical level.
