[Footnote 1: As in the picture by Lo Spagna in our National Gallery, No. 282.]
There are examples where the angels in attendance bear, not harps or lutes, but the attributes of the Cardinal Virtues, as in an altar-piece by Taddeo Gaddi at Florence. (Santa Croce, Rinuccini Chapel.)
The patriarchs, prophets, and sibyls, all the personages, in fact, who lived under the old law, when forming, in a picture or altar-piece, part, of the cortege of the throned Virgin, as types, or prophets, or harbingers of the Incarnation, are on the outside of that sacred compartment wherein she is seated with her Child. This was the case with all the human personages down to the end of the thirteenth century; and after that time, I find the characters of the Old Testament still excluded from the groups immediately round her throne. Their place was elsewhere allotted, at a more respectful distance. The only exceptions I can remember, are King David and the patriarch Job; and these only in late pictures, where David does not appear as prophet, but as the ancestor of the Redeemer; and Job, only at Venice, where he is a patron saint.
The four evangelists and the twelve apostles are, in their collective character in relation to the Virgin, treated like the prophets, and placed around the altar-piece. Where we find one or more of the evangelists introduced into the group of attendant “Sanctities” on each side of her throne, it is not in their character of evangelists, but rather as patron saints. Thus St. Mark appears constantly in the Venetian pictures; but it is as the patron and protector of Venice. St. John the Evangelist, a favourite attendant on the Virgin, is near her in virtue of his peculiar relation to her and to Christ; and he is also a popular patron saint. St. Luke and St. Matthew, unless they be patrons of the particular locality, or of the votary who presents the picture, never appear. It is the same with the apostles in their collective character as such; we find them constantly, as statues, ranged on each side of the Virgin, or as separate figures. Thus they stand over the screen of St. Mark’s, at Venice, and also on the carved frames of the altar-pieces; but either from their number, or some other cause, they are seldom grouped round the enthroned Virgin.
