For a building which owes its general impressiveness entirely to the uniform character of its architecture, it is especially fortunate that there should be so much also in the detail to attract and reward constant and minute examination. It is for this reason that the range of great capitals to the columns of the lower arcade is of so much importance. They are so large, so close to the eye, so interesting in their story, and on the whole so carefully and artistically executed, as to afford the greater pleasure the more the building is known. The key-plan to these capitals which I give[51] will be useful to shew what the general arrangement of the subjects is. I have already shewn that there are repetitions of many of the subjects, but it is equally worth notice that the foliage which forms the framework for the subjects is also repeated. There are, I think, only four varieties in its arrangement. In the first the capitals are arranged very simply--in some cases rudely--with tufts of foliage or heads. The capitals numbered 2, 3, 6, 13, 16, 20, 23, 27, and 34, are examples of this. In the next the foliage of the lower part grows up vertically, bending slightly out to support the sculptured subjects. These are generally the most graceful of all, and infinitely richer in effect than the first class. The capitals numbered 1, 7, 9, 12, 18, 24, 26, 28, 33, and 36, are examples of these. In the third class the foliage is generally marked by the same feeling, but it rises vertically to the angles, and curls over under the subject; the 19th and 25th capitals are examples of this class. In the fourth class the foliage curves over downwards, both at the angles and under the subject. The neckings below the capitals are wrought on the shaft itself. They are sometimes moulded, sometimes corded, and sometimes delicately carved with foliage; these last are by very much the more beautiful, and generally accompany the best wrought of the capitals, whilst the inferior capitals have, in all cases, the plainer necking.
