A nimbus or halo in religious art—seen in Christian icons, Hindu depictions of deities, and Buddhist statues—is a visual symbol of sanctity, enlightenment, or divine energy. In poetry, the term is used to describe a radiant aura surrounding a person, object, or even a moment, infusing it with a sense of the sacred or the sublime. It transforms the ordinary into the numinous, marking a point where the divine breaks through into the mundane world, and serves as a powerful image of recognized holiness.

The nimbus (halo) originated in Hellenistic art and was adopted in Christian, Buddhist, and Hindu iconography to signify sanctity; its circular form implies perfection and divine light emanating from within; in poetry, halos may be literal or metaphorical—describing a face “ringed with grace” or a moment charged with unspoken holiness.
