The artist Leonardo da Vinci embodies both modern intellect and the combination of 1SUPER expression in art and science: a thinker, a poet and a wizard, Leonardo da Vinci is an artist whose fascination is still 2RIVALRY today. While studying his art in its 3COMPARE variety, we find in his very caprices, to use Edgar Quinet’s motto with a slight modification, “the laws of the Italian Renaissance and the geometry of universal beauty”. Outside a small number of his finished compositions: The Last Supper, Saint Anne, the Mona Lisa, his painted and sculpted works were left to us in 4MARVEL fragments. We must turn to his drawings to understand all the 5TENDER of his heart and all the 6WELL of his great imagination. There are two specific periods of human life that fixed Leonardo da Vinci’s attention: 7ADOLESCENT and old age; childhood and 8MATURE had less interest for him. He has left us a whole series of adolescent types, some dreamy some ardent. In modern art, I can think of no creations so free, superb, spontaneous, in a word, divine to oppose to the marvels of antiquity.
