Study of a Bull, 1991, has never been publicly seen, reproduced, discussed or written aboutIt could be a bull backing in to a burning, black void or one escaping it, moving hopefully into the heavenly light. What seems certain is that this final, extraordinary painting by Francis Bacon, unseen and undocumented until now, is by an artist who knows he is soon to die.
