Here is a nice piece of his art and a poem entitled Afterwards:
There is a silence in the world
Since we have said farewell;
And beauty with an alien speech
An alien tale would tell.
There is a silence in the world,
Which is not peace nor quiet:
Ever I seek to flee therefrom,
And walk the ways of riot.
But when I hear the music moan
In rooms of thronging laughter,
A tongueless demon drives me forth,
And silence follows after.
And now I know what my nightmares are going to be about tonight.
