" But among the elect, martyrdom is always a possibility; and to be an artist is not altogether a choice - the God of Art picks you, not the other way around. Therefore the artistic vocation has an aura of tragedy and doom about it. 'We poets in our youth begin in gladness,' said Wordsworth, 'But thereof comes in the end despondency and madness.' Consider Franz Kafka's story, 'A Fasting-Artist.' The fasting-artist is an artist dedicated completely to his art. This art is grotesque: the artist stays in a cage and starves himself— much like a self-mortifying Christian ascetic of old — and at first he is very popular: crowds flock to marvel at him. Then fashions change - the art-for-art's sake fashion was by Kafka's time falling out of widespread favour — and the fasting-artist ends up in a neglected corner of a circus menagerie, and people forget he's in the cage. Finally they poke around in the rotten straw and rediscover him, more dead than alive. Here's what happens next:
'I always wanted you to admire my fasting,' said the fasting-artist. 'And we do admire it,' said the overseer obligingly. 'But you shouldn't admire it,' the fasting-artist said. 'All right, we don't admire it then,' said the overseer, 'but why shouldn't we admire it?' 'Because I have to fast, I can't help it,' said the fasting-artist. 'Whatever next,' said the overseer. 'And why can't you help it?' 'Because,' said the fasting-artist... 'I could never find the nourishment I liked. Had I found it, believe me, I would never have caused any stir, and would have eaten my fill just like you and everyone else.' Those were his last words.. . "
