"Perhaps the greatest source of wonder in Liszt's life was that he composed anything at all, let alone anything of lasting greatness. The man who, from an early age, had crisscrossed Europe as the greatest travelling virtuoso, providing, with the onset of puberty, much material for gossip columns, might have been forgiven for taking the Wildean view, 'My art is my life', and leaving it at that. [...] Exactly how Liszt could have found the time to compose is difficult to imagine."
