I shall not trace from this embryo the progress of Gothic art in Italy, because it is much complicated and involved with traditions of other schools, and because most of the students will be less familiar with its results than with their own northern buildings. So, these two designs indicating Death and Life in the beginnings of mediaeval art, we will take an example of the _progress_ of that art from our northern work. Now, many of you, doubtless, have been interested by the mass, grandeur, and gloom of Norman architecture, as much as by Gothic traceries; and when you hear me say that the root of all good work lies in natural facts, you doubtless think instantly of your round arches, with their rude cushion capitals, and of the billet or zigzag work by which they are surrounded, and you cannot see what the knowledge of nature has to do with either the simple plan or the rude mouldings. But all those simple conditions of Norman art are merely the expiring of it towards the extreme north. Do not study Norman architecture in Northumberland, but in Normandy, and then you will find that it is just a peculiarly manly, and practically useful, form of the whole great French school of rounded architecture. And where has that French school its origin? Wholly in the rich conditions of sculpture, which, rising first out of imitations of the Roman bas-reliefs, covered all the façades of the French early churches with one continuous arabesque of floral or animal life. If you want to study round-arched buildings, do not go to Durham, but go to Poictiers, and there you will see how all the simple decorations which give you so much pleasure even in their isolated application were invented by persons practised in carving men, monsters, wild animals, birds, and flowers, in overwhelming redundance; and then trace this architecture forward in central France, and you will find it loses nothing of its richness--it only gains in truth, and therefore in grace, until just at the moment of transition into the pointed style, you have the consummate type of the sculpture of the school given you in the west front of the Cathedral of Chartres. From that front I have chosen two fragments to illustrate it. [Footnote: This part of the lecture was illustrated by two drawings, made admirably by Mr. J. T. Laing, with the help of photographs from statues at Chartres. The drawings may be seen at present at the Kensington Museum: but any large photograph of the west front of Chartres will enable the reader to follow what is stated in the lecture, as far as is needful.]
