“Coign” originates in fortification but becomes metaphorical in poetry for strategic observation. Shakespeare’s “coign of vantage” describes a place to witness events unseen. Poets use it to explore perspective—literal and moral—where the observer judges, laments, or plans. Its architectural origin grounds abstract insight in physical space, enriching themes of surveillance, fate, or revelation.

“Coign” (from “coin,” meaning corner) is best known from Shakespeare’s “coign of vantage”; in poetry, it denotes a strategic or observational perch, often metaphorical—e.g., a poet’s “coign” from which to critique society or fate.
