From the point of view of thought the inscription is based upon the mystic doctrine of the differing forms of fire given by Mr. Pater in his study of ‘ Pico della Mirandola,’ and resumed in the formula, ‘the elemental burns, the heavenly vivifies, ‘ the supercelestial loves.’ In the pictures, where the first is merely of the nature of a prologue, each fire—the fire of passion consuming, the fire of life vitalising, the fire of love adoring—is portrayed in operation and effect. As a chronicle of events the series is no less complete.

“So that all things are full of divine natures; terrestrial natures receiving the plenitude of such as are celestial, but celestial of supercelestial essences; while every order of things proceeds gradually, in a beautiful descent, from the highest to the lowest. For whatever particulars are collected into one above the order of things, are afterwards dilated in descending, various souls being distributed under their various ruling divinities.”
