The above is quite clearly a painting of the Vision at Ostia, which I've talked about before.
And we came at last to our own minds and went beyond them, that we might climb as high as that region of unfailing plenty where thou feedest Israel forever with the food of truth, where life is that Wisdom by whom all things are made, both which have been and which are to be. Wisdom is not made, but is as she has been and forever shall be; for "to have been" and "to be hereafter" do not apply to her, but only "to be," because she is eternal and "to have been" and "to be hereafter" are not eternal.
[Augustine, Confessions Book IX, Chapter 10]
