The Neoclassical Revival style, which is a continuation of Classicism, is characterised by simplicity, harmony, and refined proportions. Architects sought to distance themselves from earlier stylistic periods and their tendencies to overload buildings with decorative elements. Instead, they established a set of rules for proportioning buildings.
The rules carefully defined the "correct" ratios between the width and height of the facade, the proportions of the windows, as well as the ratio between window openings and pillars, etc.
The Neoclassical Revival window is designed with a raised transom, so that the division of the upper and lower sashes follows the rules of the golden ratio, just like the Neoclassical. The panes are the same size and are divided by muntins that help spread the incoming light.
