One of the most interesting anticipations of a set of ideas that are definitely considered quite modern, and indeed have developed so recently that we are not quite sure of all their significance as yet, is Leonardo da Vinci's occupation with muscular movements and the saving of time and labor by carefully regulating these movements. He suggested that each different kind of work done by human muscular labor should be carefully studied, with the idea of simplifying and reducing the number of movements necessary for its accomplishment in order to save both time and effort. In a word he anticipated practically the modern ideas of the efficiency engineer of the present time though, as I have said, we are rather prone to think these ideas quite new and recent. The personality of this universal genius is one of the most interesting that mankind has to study. Every detail is of special import. Leonardo da Vinci was born of the noble Florentine house of Vinci in the Val d'Arno. He was a precocious child, attracting attention by his beauty of feature and by his winning ways. There are stories of his improvising music and songs even when he was very young. A little later we hear of him pitying the caged songbirds and buying them and setting them free. As a growing boy he liked colors; indeed, they may almost be said to have had a fascination for him, and the bright dresses of the Florentine girls and of the peasants from the vicinity caught his eye. Tradition also connects him with a fancy for spirited horses. As if these were not enough to show an artistic temperament, while still scarcely more than a boy he began to design and sketch and even mould objects that he was interested in. Vasari's stories of him show that even at this early date, when he was only a boy, his sketches and plastic work had for subjects smiling women. His vocation seemed clear and his father took him for education to the workshop of Andrea del Verrocchio, then the greatest artist in Florence and one whose work has always maintained an influence over succeeding generations. Those of us who have seen his "Colleoni" in Venice are likely to think {27} of him as a great sculptor. Undoubtedly he was one of the great sculptors of the world, but he had the broad artistic spirit of the men of the Renaissance, and there was no form of art in which he was not interested and in which he did not accomplish things worthy of his great time to be the admiration of succeeding generations. Verrocchio was a great painter as well as a sculptor, but he was also a worker in metals and, as so many of these artists of the Renaissance, quite ready to design household objects for even ordinary use, provided only he was allowed to put beauty in them. Drinking vessels, instruments of music, gates, wooden doors and above all any objects that were meant for sacred uses he was glad to take commissions for.
