117. _Physical_ purity;--actual love of sweet light, and of fair colour. This is one palpable sign, and an entirely needful one, that we have got what we pretend to pray for every morning. That, you will find, is the meaning of Apollo's war with the Python--of your own St. George's war with the dragon. You have got that battle stamped again on every sovereign in your pockets, but do you think the sovereigns are helping, at this instant, St. George in his battle? Once, on your gold of the Henrys' times, you had St. Michael and the dragon, and called your coins 'angels.' How much have they done lately, of angelic work, think you, in purifying the earth? 118. Purifying, literally, purging and cleansing. That is the first "sacred art" all men have to learn. And the words I deferred to the close of this lecture, about the proposed improvements in Oxford, are very few. Oxford is, indeed, capable of much improvement, but only by undoing the greater part of what has been done to it within the last twenty years; and, at present, the one thing that I would say to well-meaning persons is, 'For Heaven's sake--literally for Heaven's sake--let the place alone, and clean it.' I walked last week to Iffley--not having been there for thirty years. I did not know the church inside; I found it pitch-dark with painted glass of barbarous manufacture, and the old woman who showed it infinitely proud of letting me in at the front door instead of the side one. But close by it, not fifty yards down the hill, there was a little well--a holy well it should have been; beautiful in the recess of it, and the lovely ivy and weeds above it, had it but been cared for in a human way; but so full of frogs that you could not have dipped a cup in it without catching one. What is the use of pretty painted glass in your churches when you have the plagues of Egypt outside of them? 119. I walked back from Iffley to Oxford by what was once the most beautiful approach to an academical city of any in Europe. Now it is a wilderness of obscure and base buildings. You think it a fine thing to go into Iffley church by the front door;--and you build cheap lodging-houses over all the approach to the chief university of English literature! That, forsooth, is your luminous cloister, and porch of Polygnotus to your temple of Apollo. And in the centre of that temple, at the very foot of the dome of the Radclyffe, between two principal colleges, the lane by which I walked from my own college half an hour ago, to this place,--Brasen-nose Lane--is left in a state as loathsome as a back-alley in the East end of London. 120. These, I suppose, are the signs of extending liberality, and disseminated advantages of education.
