Walter Pator does Mona Lisa producing epiphany

Thus far I have not been able to find what I am looking for concerning Walter Pater and epiphanic realizations. I did however find some readings about his critique of the Renaissance painting of Mona Lisa that sheds some light on how he perceived notions of "Awe" within the famous painting:

"She is older than the rocks among which she sits; like the vampire, SHE HAS BEEN DEAD MANY TIMES, and learned the secrets of the grave; and has been a diver in deep seas, and keeps their fallen day about her; and trafficked for strange webs with Eastern merchants; and, as Leda, was the mother of Helen of Troy, and, as Saint Anne, the mother of Mary; and all this has been to her but as the sound of lyres and flutes, and lives only in the delicacy with which it has moulded the changing lineaments, and tinged the eyelids and the hands. THE FANCY OF A PERPETUAL LIFE, SWEEPING TOGETHER TEN THOUSAND EXPERIENCES, is an old one; and modern philosophy has conceived the idea of humanity as wrought upon by, and summing up in itself, all modes of thought and life. Certainly Lady Lisa might stand as the embodiment of the old fancy, the symbol of the modern idea".

In this paragraph, Pater uses words that further produce a feeling of mysticism in the painting of a long since dead woman, which rework what I think is a boring painting into a much more significant symbol of perfection. When he says that "she has been dead many times" I understood that this painting has been created and re-created many times thus allowing Lady Lisa to be reborn in our minds as an icon of perfection or (for some) maybe a rather insignificant portrait of a rather odd looking woman. What I understand though, is that this painting is majestic because people have maintained a steady stream of re-invention that now has a undertone of immortality. This is in fact a perfect representation of how an epic epiphany should haunt those afflicted by its indescribable power, as Walter was. I believe that Pater actually makes this painting much more epiphanic than it originally was with his description. He is able to imprint a deeper sense of the mysticism by pointing out that the Mona Lisa is "the fancy of perpetual life, sweeping together ten thousand experiences", which is once again demonstrating the everlasting quality of the painting itself, except this time it is directly playing on the audience's awareness of their own "experiences" and feelings toward the painting itself. If you were to go to the place where the Mona Lisa is currently on display, the energy in the room might equal that of an epiphanic moment because everyone would be eye-goggling this strange wonder together adding to the atmosphere of Awe within the room. If Walter Pater were present at such a moment I think he would blurt out, "How shall we pass most swiftly from point to point, and be present always at the focus where the greatest number of vital forces unite in their purest energy? To burn always with this hard, gem-like flame, to maintain this ecstasy, is success in life". "Pure energy" would equal that of the atmosphere in the room and the "gem-like" flame would be what everyone would be afflicted with when they leave. Truly this would be a wonderful moment of ecstasy!
