In painting, where a glory of angels is placed round the Divine Being or the glorified Virgin, those forming the innermost circles are or ought to be of a glowing red, the colour of fire, that is, of love; the next circle is painted blue, the colour of the firmament, or light, that is, of knowledge. Now as the word seraph is derived from a Hebrew root signifying love, and the word cherub from a Hebrew root signifying to know, should not this distinction fix the proper place and name of the first two orders? It is admitted that the spirits which _love_ are nearer to God than those which _know_, since we cannot know that which we do not first love: that Love and Knowledge, ‘the two halves of a divided world,’ constitute in their union the perfection of the angelic nature; but the Seraphim, according to the derivation of their name, should _love_ most; their whole being is fused, as it were, in a glow of adoration; therefore they should take the precedence, and their proper colour is red. The Cherubim, ‘the lords of those that know,’ come next, and are to be painted blue. Thus it should seem that, in considering the religious pictures of the early ages of Art, we have to get rid of certain associations as to colour and form, derived from the phraseology of later poets and the representations of later painters. ‘Blue-eyed Seraphim,’ and the ‘blue depth of Seraph’s eyes,’ are not to be thought of any more than smiling Cherubim.’ The Seraphim, where distinguished by colour, are red; the Cherubim blue: the proper character, where character is attended to, is, in the Seraph, adoration; in the Cherub, contemplation. So Milton— With thee bring Him who soars on golden wing, The Cherub, Contemplation. I remember a little Triptyca, a genuine work of Fiesole, in which one of the lateral compartments represents his favourite subject, the souls of the blessed received into Paradise. They are moving from the lower part of the picture towards the top, along an ascent paved with flowers, all in white garments and crowned with roses. At one side, low down, stands a blue Cherub robed in drapery spangled with golden stars, who seems to encourage the blessed group. Above are the gates of heaven. Christ welcomes to his kingdom the beatified spirits, and on each side stands a Seraph, all of a glowing red, in spangled drapery. The figures are not here merely heads and wings, but full length, having all that soft peculiar grace which belongs to the painter.[21]
