Final answer:
The Palazzo Rucellai in Florence, designed by Leon Battista Alberti, highlights features of Renaissance architecture including an organized facade with three stories, classical elements like pilasters and round arches, and a decorative cornice, all reflecting the Humanist emphasis on light and clarity.
Step-by-step explanation:
The Palazzo Rucellai, designed by Leon Battista Alberti between 1446-and 1451 in Florence, showcases several key features of early Renaissance architecture. The facade of this palatial townhouse is organized into three stories, with each story adorned with pilasters, each bearing a different capital, and a set of classical architectural features such as pilasters, round arches, and an entablature with a decorative frieze which all contribute to a harmonious proportional relationship. Additionally, there are benches carved with a diamond pattern on the ground floor, while the first floor boasts square windows. The second and third floors feature windows with mullions that divide each window vertically. A decorative cornice beautifully caps the building at the top. The presence of these features reflects the Humanist philosophy of light, clarity, and cognitive enlightenment that characterized the Renaissance period.
