'Take, for instance, a characteristic work of the middle age, Angelico's Coronation of the Virgin, in the cloister of Saint Mark's at Florence. In some strange halo of a moon Christ and the Virgin Mary are sitting, clad in mystical white raiment, half shroud, half priestly linen. Our Lord, with rosy nimbus and the long pale hair, tanquam lana alba et tanquam nix, of the figure in the Apocalypse, sets, with slender finger tips, a crown of pearl on the head of his mother, who, corpse-like in her refinement, bends to receive it, the light lying like snow upon her forehead. Certainly, it cannot be said of Angelico's fresco that it throws into a sensible form our highest thoughts about man and his relation to the world; but it did not do this adequately even for Angelico. For him all that is outward or sensible in his work—the hair like wool, the rosy nimbus, the crown of pearl—is only the symbol or type of an inexpressible world, to which he wishes to direct the thoughts; he would have shrunk from the notion that what the eye apprehended was all.' (101-102)
