He was also a great engineer and architect, designing many of the chief structures and public works of Milan. His scientific notebooks are filled with studies and analyses of problems in dynamics, anatomy, physics, optics, biology, hydraulics, and even aeronautics, all far in advance of his time. He was an experimental scientist long before the formulation of the so-called scientific method.
Leonardo was also, according to all accounts, a man of high moral character, gracious and kind in all dealings. Although his few extant manuscripts deal with art or science, rather than theology, there is no doubt that he wa s a sincere believer in Christ and the Scriptures, as well as the general faith of the church. If nothing else were available to give this testimony, his great work of art, The Last Supper, with its profound insights into the heart of Christ and the disciples, a painting that has blessed and stirred the souls of multitudes over the centuries, would bear witness of his faith.
