Leonardo di ser Piero da Vinci (April 15, 1452 - May 2, 1519) was an Italian Renaissance polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer. His genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. Leonardo has often been described as the archetype of the Renaissance Man, a man of "unquenchable curiosity" and "feverishly inventive imagination." He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived. This edition, edited by Maurice Baring, is a collection of his notes concerning a wide variety of subjects such as Life, Art and the Sciences. Maurice Baring (27 April 1874 - 14 December 1945) was an English man of letters, known as a dramatist, poet, novelist, translator and essayist, and also as a travel writer and war correspondent.
