And now, by glancing back to Plate X. Vol. II, the reader will see in a moment the kind of evidence which is found of the date of capitals in their profiles merely. Observe: we have seen that the treatment of the leaves in the Madonnetta House seemed "indicative of a tendency to transition." Note their profile, 1_a_, and its close correspondence with 1 _h_, which is actually of a transitional capital from the upper arcade of second order windows in the Apostoli Palace; yet both shown to be very close to the Byzantine period, if not belonging to it, by their fellowship with the profile _i_, from the Fondaco de' Turchi. Then note the close correspondence of all the other profiles in that line, which belong to the concave capitals or plinths of the Byzantine palaces, and note their composition, the abacus being, in idea, merely an echo or reduplication of the capital itself; as seen in perfect simplicity in the profile _f_, which is a roll under a _tall_ concave curve forming the bell of the capital, with a roll and _short_ concave curve for its abacus. This peculiar abacus is an unfailing test of early date; and our finding this simple profile used for the Ducal Palace (_f_), is strongly confirmatory of all our former conclusions. Then the next row, 2, are the Byzantine and early Gothic semi-convex curves, in their pure forms, having no roll below; but often with a roll added, as at _f_, and in certain early Gothic conditions curiously fused into it, with a cavetto between, as _b_, _c_, _d_. But the more archaic form is as at _f_ and _k_; and as these two profiles are from the Ducal Palace and Piazzetta shafts, they join again with the rest of the evidence of their early date. The profiles _i_ and _k_ are both most beautiful; _i_ is that of the great capitals of the Ducal Palace, and the small profiles between it and _k_ are the varieties used on the fillet at its base. The profile _i_ should have had leaves springing from it, as 1 _h_ has, only more boldly, but there was no room for them. The reader cannot fail to discern at a glance the fellowship of the whole series of profiles, 2 _a_ to _k_, nor can he but with equal ease observe a marked difference in 4 _d_ and 4 _e_ from any others in the plate; the bulging outlines of leafage being indicative of the luxuriant and flowing masses, no longer expressible with a simple line, but to be considered only as confined within it, of the later Gothic. Now _d_ is a dated profile from the tomb of St. Isidore, 1355, which by its dog-tooth abacus and heavy leafage distinguishes itself from all the other profiles, and therefore throws them back into the first half of the century. But, observe, it still retains the noble swelling root. This character soon after vanishes; and, in 1380, the profile _e_, at once heavy, feeble, and ungraceful, with a meagre and valueless abacus hardly discernible, is characteristic of all the capitals of Venice.
