I think that the most important requirement is to capture the essence of a piece of art. You look at it, essentially absorb it, and you have to be able to understand it visually without having to think about how it was done. I was already able to do that as a child.

Most forgers are caught because they tell the wrong person about what they do.

I can paint anything. Leonardo? Of course. But why? You couldn't sell it.

The trick is to paint a picture that doesn't exist, and yet that fits perfectly into an artist's body of work.

I once went to a demonstration in Aachen against fare increases on public transport. A police officer pulled out a bunch of my hair, and there were a lot of violent beatings. That's when I thought to myself: You'd better leave it alone.

I went to the flea market in the morning and charged tourists money to take pictures of me. I looked pretty wild, with hair down to my waist, Indian robes, a floor-length fur coat. There must be lots of photos of me out there.

Every philharmonic orchestra merely interprets the composer. My goal was to create new music by that composer. In doing so, I wanted to find the painter's creative center and become familiar with it, so that I could see through his eyes how his paintings came about and, of course, see the new picture I was painting through his eyes - before I even painted it.
