I wanted to say something different: the pictures are also a leave-taking, in several respects. Factually: these specific persons are dead; as a general statement, death is leave-taking. And then ideologically: a leave-taking from a specific doctrine of salvation and, beyond that, from the illusion that unacceptable circumstances of life can be changed by this conventional expedient of violent struggle.

They are specific places I have discovered here and there when I am on the road to take photos. I go especially to take photos.

Not the victims of any specific ideology of the left or of the right, but of the ideological posture as such. This has to do with the everlasting human dilemma in general: to work for a revolution and fail.

It was not possible for us to produce the same optimism and the same kind of humour or irony. Actually, it was not irony. Lichtenstein is not ironic but he does have a special kind of humour. That's how I could describe it: humour and optimism. For Polke and me, everything was more fragmented. But how it was broken up is hard to describe.

Photography has almost no reality; it is almost a hundred per cent picture. And painting always has reality: you can touch the paint; it has presence; but it always yields a picture - no matter whether good or bad. That's all the theory. It's no good. I once took some small photographs and then smeared them with paint. That partly resolved the problem, and it's really good - better than anything I could ever say on the subject.

There was no special event that made me decide. I had collected some photos and the idea was in the back of my mind for a long time. It was growing and growing, so finally I said, 'I must paint this.' I come from East Germany and am not a Marxist, so of course at the time I had no sympathy for the ideas, or for the ideology that these people represented. I couldn't understand, but I was still impressed. Like everyone, I was touched. It was an exceptional moment for Germany.

I didn't actually know what the protesters in the West really wanted. It was fantastic here, so much freedom, and that was what they were calling musty, middle-class, and fascistic, a bleak period. Bleak was what the GDR was, and it alone had adopted, almost unchanged, Nazi Germany's methods of intimidation and ideas about propaganda and the use of force.
