A luminous circle, usually prismatically colored, round the sun or moon, and supposed to be caused by the refraction of light through crystals of ice in the atmosphere. Connected with halos there are often white bands, crosses, or arches, resulting from the same atmospheric conditions.
A circle of light; especially, the bright ring represented in painting as surrounding the heads of saints and other holy persons; a glory; a nimbus.
An ideal glory investing, or affecting one's perception of, an object.
A colored circle around a nipple; an areola.
To form, or surround with, a halo; to encircle with, or as with, a halo.
When you're in love you never really know whether your elation comes from the qualities of the one you love, or if it attributes them to her; whether the light which surrounds her like a halo comes from you, from her, or from the meeting of your sparks. Natalie Clifford Barney
