Quick Definition

A vertical or horizontal bar dividing a window into sections. It may symbolize separation, framing, or the way vision is organized.

Detailed Definition
A mullion is the structural member that divides a window or screen into smaller panes or lights. In poetry, it offers a precise image for divided perception: one scene fractured into several views, a face seen through old glass, or memory broken into bright compartments. Mullions can also suggest the necessary framework that makes vision possible. A poet may contrast the openness of light with the bars that shape it, exploring confinement, perspective, and the patterned limits of seeing.
Example
Example in poetry:
“A mullion divides the window into four blue panes” precisely identifies the vertical or horizontal bar separating sections of glazing; A poet may use mullions to frame separate views, such as one pane holding sea and another holding storm; “Through the mullion’s cross, the garden breaks into green quarters” links window structure to visual fragmentation; Stanzas separated by recurring short lines can imitate mullions dividing a larger poetic vision
Additional Notes
A mullion divides a window while helping it hold its shape. It can represent barriers in perception, divided viewpoints, or the visual framing of memory.
