Living and working for four decades in a Bologna apartment and studio he shared with his unwed sisters, Morandi painted little but bottles, boxes, jars, and vases. Yet like that of Chardin and the underappreciated William Nicholson, Morandi's work seems to slow down time and show you things you've never seen before.

Galleries needn't be exactly like White Columns purely because times are bad again. But the idea of this special space could - should - help shape what comes next.

After 1909, Monet drastically enlarged his brushstrokes, disintegrated his images, and broke through the taming constraints and delicacy of Impressionism for good. Nineteen gnarly paintings, starting in 1909 and carrying through his final seventeen years, finish off the notion that Monet went happily ever after into lily-land.

As I made my way through 'On Line,' the austere, stridently dogmatic, sometimes revelatory exhibition 'about line' at MoMA, I found myself thinking, 'Someone please wake me when the seventies are over!' In the empire of curators, the sun never sets on the seventies. It is the undead decade.

It is not possible to overstate the influence of Paul Cezanne on twentieth-century art. He's the modern Giotto, someone who shattered one kind of picture-making and invented a new one that the world followed.

After its hothouse incubation in the seventies, appropriation breathed important new life into art. This life flowered spectacularly over the decades - even if it's now close to aesthetic kudzu.

These days, newish art can be priced between $10,000 and $25,000. When I tell artists that a new painting by a newish artist should go for around $1,200, they look at me like I'm a flesh-eating virus.
