Think of an abstract painting as very, very low relief - a thing, not a picture.

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.

Although I adore the Italian High Renaissance, I'd rather look at Mannerism. The former is ordered, integrated, otherworldly, and grandiose; it leaves you feeling hungry for something flawed and of-the-flesh.
