Consider Le Corbusier's Poissy bei Paris, Villa Savoye, and Francesco Borromini's San Carlo alle Quattro Fontane in Rome. Identify the historical eras in which each architect worked. Then analyze the visual rhythms and use of symmetry and proportion in these buildings, noting how these characteristics impact our understanding of them.

What will be an ideal response?

Answers will vary, but they should touch upon the following:
Borromini worked in the seventeenth century C.E. and Le Corbusier worked from the late nineteenth century into the twentieth century. 
Visual Rhythm: Borromini used rhythms to articulate the façade (exterior face) of the church. A repeating vertical rhythm of columns, along with projecting and recessing walls create an undulating rhythm. Le Corbusier's structure has a static rhythm, which comes partially from the even repetition of same-sized shapes. 
Symmetry and Proportion: The façade of Alberti's church is symmetrical, the design elements on both sides even and the same. Doors and windows are huge. Le Corbusier used the golden section for the Modulor to create a practical proportion. The building is mostly symmetrical, using symmetrical shapes in both the overall design and component parts (windows, pillars, walls). Le Corbusier was conscious of making a building of normal proportions to create a comfortable living situation for its human occupants.
