Now it will be observed, that there is in its treatment a high degree of abstraction, though not so conventional as that of Salisbury: that is to say, the leaves have little more than their flow and outline represented; they are hardly undercut, but their edges are connected by a gentle and most studied curve with the stone behind; they have no serrations, no veinings, no rib or stalk on the angle, only an incision gracefully made towards their extremities, indicative of the central rib and depression. The whole style of the abstraction shows that the architect could, if he had chosen, have carried the imitation much farther, but stayed at this point of his own free will; and what he has done is also so perfect in its kind, that I feel disposed to accept his authority without question, so far as I can gather it from his works, on the whole subject of abstraction. XXXII. Happily his opinion is frankly expressed. This moulding is on the lateral buttress, and on a level with the top of the north gate; it cannot therefore be closely seen except from the wooden stairs of the belfry; it is not intended to be so seen, but calculated for a distance of, at least, forty to fifty feet from the eye. In the vault of the gate itself, half as near again, there are three rows of mouldings, as I think, by the same designer, at all events part of the same plan. One of them is given in Plate I. fig. 2 _a_. It will be seen that the abstraction is here infinitely less; the ivy leaves have stalks and associated fruit, and a rib for each lobe, and are so far undercut as to detach their forms from the stone; while in the vine-leaf moulding above, of the same period, from the south gate, serration appears added to other purely imitative characters. Finally, in the animals which form the ornaments of the portion of the gate which is close to the eye, abstraction nearly vanishes into perfect sculpture.
