"De Prospectiva Pingendi" is a treatise on perspective in painting, authored by the Italian artist and architect Leon Battista Alberti in the 15th century. This work is significant for its systematic approach to the principles of perspective, which allows artists to create the illusion of depth and three-dimensionality on a flat surface. In the text, Alberti outlines techniques for accurately representing spatial relationships and the placement of objects within a composition. His ideas laid the groundwork for future developments in art and influenced many artists during the Renaissance and beyond, making it a foundational text in the study of visual representation.
