The art of our century has been dominated by two men: Henri Matisse and Pablo Picasso. They are artists of classical greatness, and their visionary forays into new art have changed our understanding of the world. Matisse was the elder of the two, but he was a slower and more methodical man by temperament and it was Picasso who initially made the greater splash. Matisse, like Raphael, was a born leader and taught and encouraged other painters, while Picasso, like Michelangelo, inhibited them with his power: he was a natural czar.
