He was an engineer, made bridges, fortifications, and plans which to this day are brilliant achievements.
He was a sculptor, and as such did beautiful work.
He was a naturalist, and as such was of use to the world.
He was an author and left behind him books written backward, of which he said that only he who was willing to devote enough study to them to read them in that form, was able to profit by what he had written.
Finally, and most wonderfully, he was a painter.
He had absolute faith in himself. Before he constructed his bridge he said that he could build the best one in the world, and a king took him at his word and was not disappointed by the result.
He stated that he could paint the finest picture in the world--but let us read what he himself said of it, in so sure and superbly confident a way that it robbed his statement of anything like foolish vanity. Such as he could afford to speak frankly of his greatness, without appearing absurd. He wrote:
"In time of peace, I believe I can equal anyone in architecture, in constructing public and private buildings, and in conducting water from one place to another. I can execute sculpture, whether in marble, bronze, or terra cotta, and in painting I can do as much as any other man, be he who he may. Further, I could engage to execute the bronze horse in eternal memory of your father and the illustrious house of Sforza." He was writing to Ludovico Sforza whose house then ruled at Milan. "If any of the above-mentioned things should appear to you impossible or impracticable, I am ready to make trial of them in your park, or in any other place that may please your excellency, to whom I commend myself in proud humility."
Leonardo's experiments with oils and the mixing of his pigments has nearly lost to us his most remarkable pictures. His first fourteen years of work as an artist were spent in Milan, where he was employed to paint by the Duke of Milan, and never again was his life so peaceful; it was ever afterward full of change. He went from Milan to Venice, to Rome, to Florence, and back to Milan where his greatest work was done.
While Leonardo was a baby he lived in the Castle of Vinci. He was beautiful as a child and very handsome as a man. When a child he wore long curls reaching below his waist. He was richly clothed, and greatly beloved. His body seemed no less wonderful than his mind. He wished to learn everything, and his memory was so wonderful that he remembered all that he undertook to learn. His muscles were so powerful that he could bend iron, and all animals seemed to love him. It is said he could tame the wildest horses. Indeed his life and accomplishments read as if he were one enchanted. One writer tells us that "he never could bear to see any creature cruelly treated, and sometimes he would buy little caged birds that he might just have the pleasure of opening the doors of their cages, and setting them at liberty."
