This lesson plan aims to teach 17-18 year old students about compositional structure in Renaissance and Baroque art through examples of representative artworks. In the 60 minute lesson, students will first learn how Renaissance artists like Giotto, Leon Battista Alberti, and Botticelli used mathematical ratios and geometry in their compositions to achieve harmony. They will then compare the symmetrical, pyramidal compositions of Piero della Francesca to the dynamic, diagonal compositions and use of chiaroscuro in Rubens' works. To practice these concepts, students will then simplify and interpret compositional structures from examples of Renaissance and Baroque art in their own sketches. Finally, the class will discuss what they learned about compositional structures and new art terms.
