The aureole was used in ancient days by Babylonian artists or sculptors, when they wished to represent a being, apparently human, as a god. The same plan has been adopted by the moderns, who have varied the symbol by representing it now as a golden disc, now as a terrestrial orb, again as a rayed sphere. A writer, when describing a god as a man, can say that the object he sketches is divine; but a painter thinks too much of his art to put on any of his designs, "this woman is a goddess," or "this creature is a god"; he therefore adds an aureole round the head of his subject, and thus converts a very ordinary man, woman, or child into a deity to be reverenced; modern artists thus proving themselves to be far more skilful in depicting the Almighty than the carpenters and goldsmiths of the time of Isaiah (xl. 18, 19, xli. 6, 7, xliv. 9-19), who used no such contrivance. Figure 24 is another representation of the solar disc, in which it is marked with a cross. This probably originated in the wheel of a chariot having four spokes, and the sun being likened to a charioteer. The chariots of the sun are referred to in 2 Kings xxiii. 11 as idolatrous emblems. Of these the wheel was symbolic. The identification of this emblem with the sun is very easy, for it has repeatedly been found in Mesopotamian gems in conjunction with the moon. In a very remarkable one figured in Rawlinson's Ancient Monarchies, vol. ii., p. 249, the cross is contrived as five circles. It is remarkable that in many papal pictures the wafer and the cup are depicted precisely as the sun and moon in conjunction. See Pugin's Architectural Glossary, plate iv., fig. 5. Figures 25, 26, 27, are simply varieties of the solar wheel, intended to represent the idea of the sun and moon, the mystic triad and unit, the "arba," or four. In Figure 26, the mural ornament is introduced, that being symbolic of feminine virginity. For explanation of Figure 27, see Figures 85, 86. Figure 28 is copied from Lajard, Op. Cit., plate xiv. F. That author states that he has taken it from a drawing of an Egyptian stele, made by M. E. Prisse (Monum. Egypt., plate xxxvii.), and that the original is in the British Museum. There is an imperfect copy of it in Rawlinson's Herodotus, vol. ii.
