It's something of a problem in contemporary pagan iconography.
Do gods have halos?
Halo: a disk of light surrounding the head, in art the conventional indicator of holiness. (In Greek, halo means “threshing floor”; threshing floors were clean, shining disks of ground.)
To Western eyes, halos may have something of a Christian look to them. For some, that's a problem.
But look East and you'll see that buddhas wear halos too, and so do Hindu gods.
In fact, there was a time when use of the halo was forbidden to Christian artists. Sorry, Crispus, halos are for pagans.
