||1446: Architect and designer Filippo Brunelleschi dies.  Brunelleschi was a founder of Renaissance architecture, now recognised to be the first modern engineer, planner, and sole construction supervisor. He is most famous for designing the dome of the Florence Cathedral, a feat of engineering that had not been accomplished since antiquity, as well as the development of the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science.
