aureole

n. halo, aura, radiance

An aureola or aureole (diminutive of Latin aurea, "golden") is the radiance of luminous cloud which, in paintings of sacred personages, surrounds the whole figure. In the earliest periods of Christian art this splendour was confined to the figures of the persons of the Christian Godhead, but it was afterwards extended to the Virgin Mary and to several of the saints.
