Anyone who has read about Balthus has come across this telegram which Balthus wrote to the art critic John Russell right before his Tate Gallery retrospective in London in 1968.
"No biographical details. Bathus is a painter of whom nothing is known. Now let us look at the pictures. Regards. B"
Bathus was reclusive and silent for years. In the years before his death, however, Balthus opened up to the press and we know a lot more about him. Biographys were written and art books were published.
