Perhaps the most interesting example of the style is the nave of the church of Montier-en-Der, near Vassy, almost due east from Paris. It is perfectly plain, very like San Vincenzo (Woodcut No. 408), and is a perfect Romanesque example with a wooden roof; the design for which was probably brought direct from Rome when this church was erected in this remote village. What, however, gives it its greatest interest for our present purpose arises from the fact that the apse or choir was rebuilt in the 13th century, and we have consequently in immediate juxtaposition the Romanesque model as it was introduced to the Barbarians, and the result of their elaboration of it—the germ of the Gothic style and the full-blown flower. [Illustration: 610. Section of Eastern portion of Church of Montier-en-Der. (From the ‘Archives des Monuments,’ &c.)] As before pointed out (p. 49), the progress was slow in the formation of a new style during the 1000 years that elapsed between the building of the Temple of Diana at Nîmes and the Church at Carcassonne; but here, within the limits of two, or at most three centuries, the progress made was so rapid as to be startling. The inhabitants of Central France appear at once to have comprehended the significance of the problem, and to have worked it out with a steadiness and energy of which it must be difficult to find another example. The nave of the church is as poor and as lean as it can well be, but every part of the choir is ornamented, while nothing is overdone; and there is not one single ornament which is not appropriate to its place, or which may not fairly be considered as a part of the ornamented construction of the building. It was an entirely new style invented on the spot, and complete in all its parts. Some of its ornaments were afterwards made more elegant, and more might have been done in this direction; but as here represented the style was complete, and it is certainly one of the most beautiful creations of the class which ever emanated from the activity of the human brain. It is also interesting as being one of the few where every step in the progress can be traced and every result understood. What we have now to attempt, is to point out—as clearly as our limits will admit of—the steps by which the rude architecture of the western half of the church of Montier-en-Der was converted into the perfected style of the choir as shown in the woodcut on the previous page.
