The central group is put first, that it may be seen how the series on the two sides of the apse answer each other. It was a very curious freak to insert the triangle e, in the outermost place but one of both the fourth and eighth sides of the apse, and in the outermost but two in the third and ninth; in neither case having any balance to it in its own group, and the real balance being only effected on the other side of the apse, which it is impossible that any one should see at the same time. This is one of the curious pieces of system which so often occur in mediæval work, of which the key is now lost. The groups at the ends of the transepts correspond neither in number nor arrangement; we shall presently see why, but must first examine more closely the treatment of the triangles themselves, and the nature of the floral sculpture employed upon them.

SCULPTURES OF MURANO.

§ XXIII. As the scale of Plate III. is necessarily small, I have given three of the sculptured triangles on a larger scale in Plate IV. opposite. Fig. 3 is one of the four in the lower series of Plate IV., and figs. 4 and 5 from another group. The forms of the trefoils are here seen more clearly; they, and all the other portions of the design, are thrown out in low and flat relief, the intermediate spaces being cut out to the depth of about a quarter of an inch. I believe these vacant spaces were originally filled with a black composition, which is used in similar sculptures at St. Mark’s, and of which I found some remains in an archivolt moulding here, though not in the triangles. The surface of the whole would then be perfectly smooth, and the ornamental form relieved by a ground of dark grey; but, even though this ground is lost, the simplicity of the method insures the visibility of all its parts at the necessary distance (17 or 18 feet), and the quaint trefoils have a crispness and freshness of effect which I found it almost impossible to render in a drawing. Nor let us fail to note in passing how strangely delightful to the human mind the trefoil always is. We have it here repeated five or six hundred times in the space of a few yards, and yet are never weary of it. In fact, there are two mystical feelings at the root of our enjoyment of this decoration: the one is the love of trinity in unity, the other that of the sense of fulness with order; of every place being instantly filled, and yet filled with propriety and ease; the leaves do not push each other, nor put themselves out of their own way, and yet whenever there is a vacant space, a leaf is always ready to step in and occupy it.

§ XXIV. I said the trefoil was five or six hundred times repeated. It is so, but observe, it is hardly ever twice of the same size; and this law is studiously and resolutely observed. In the carvings a and b of the upper series, Plate III., the diminution of the leaves might indeed seem merely representative of the growth of the plant. But look at the lower: the triangles of inlaid purple marble are made much more nearly equilateral than those of white marble, into whose centres they are set, so that the leaves may continually diminish in size as the ornament descends at the sides. The reader may perhaps doubt the accuracy of the drawing on the smaller scale, but in that given larger, fig. 3, Plate IV., the angles are all measured, and the purposeful variation of width in the border therefore admits of no dispute.¹⁴ Remember how absolutely this principle is that of nature; the same leaf continually repeated, but never twice of the same size. Look at the clover under your feet, and then you will see what this Murano builder meant, and that he was not altogether a barbarian.

§ XXV. Another point I wish the reader to observe is, the importance attached to color in the mind of the designer. Note especially—for it is of the highest importance to see how the great principles of art are carried out through the whole building—that, as only the white capitals are sculptured below, only the white triangles are sculptured above. No colored triangle is touched with sculpture; note also, that in the two principal groups of the apse, given in Plate III., the centre of the group is color, not sculpture, and the eye is evidently intended to be drawn as much to the chequers of the stone, as to the intricacies of the chiselling. It will be noticed also how much more precious the lower series, which is central in the apse, is rendered, than the one above it in the plate, which flanks it: there is no brick in the lower one, and three kinds of variegated marble are used in it, whereas the upper is composed of brick, with black and white marble only; and lastly—for this is especially delightful—see how the workman made his chiselling finer where it was to go with the variegated marbles, and used a bolder pattern with the coarser brick and dark stone. The subtlety and perfection of artistical feeling in all this are so redundant, that in the building itself the eye can rest upon this colored chain with the same kind of delight that it has in a piece of the embroidery of Paul Veronese.

Fig. II.

§ XXVI. Such being the construction of the lower band, that of the upper is remarkable only for the curious change in its proportions. The two are separated, as seen in the little woodcut here at the side, by a string-course composed of two layers of red bricks, of which the uppermost projects as a cornice, and is sustained by an intermediate course of irregular brackets, obtained by setting the thick yellow bricks edgeways, in the manner common to this day. But the wall above is carried up perpendicularly from this projection, so that the whole upper band is advanced to the thickness of a brick over the lower one. The result of this is, of course, that each side of the apse is four or five inches broader above than below; so that the same number of triangles which filled a whole side of the lower band, leave an inch or two blank at each angle in the upper. This would have looked awkward, if there had been the least appearance of its being an accidental error; so that, in order to draw the eye to it, and show that it is done on purpose, the upper triangles are made about two inches higher than the lower ones, so as to be much more acute in proportion and effect, and actually to look considerably narrower, though of the same width at the base. By this means they are made lighter in effect, and subordinated to the richly decorated series of the lower band, and the two courses, instead of repeating, unite with each other, and become a harmonious whole.

V.

Archivolt in the Duomo of Murano.

In order, however, to make still more sure that this difference in the height of the triangles should not escape the eye, another course of plain bricks is added above their points, increasing the width of the band by another two inches. There are five courses of bricks in the lower band, and it measures 1 ft. 6 in. in height: there are seven courses in the upper (of which six fall between the triangles), and it measures 1 ft. 10 in. in height, except at the extremity of the northern aisle, where for some mysterious reason the intermediate cornice is sloped upwards so as to reduce the upper triangles to the same height as those below. And here, finally, observe how determined the builder was that the one series should not be a mere imitation of the other; he could not now make them acute by additional height—so he here, and here only, narrowed their bases, and we have seven of them above, to six below.

§ XXVII. We come now to the most interesting portion of the whole east end, the archivolt at the end of the northern aisle.

It was above stated, that the band of triangles was broken by two higher arches at the ends of the aisles. That, however, on the northern side of the apse does not entirely interrupt, but lifts it, and thus forms a beautiful and curious archivolt, drawn opposite, in Plate V. The upper band of triangles cannot rise together with the lower, as it would otherwise break the cornice prepared to receive the second story; and the curious zigzag with which its triangles die away against the sides of the arch, exactly as waves break upon the sand, is one of the most curious features in the structure.

It will be also seen that there is a new feature in the treatment of the band itself when it turns the arch. Instead of leaving the bricks projecting between the sculptured or colored stones, reversed triangles of marble are used, inlaid to an equal depth with the others in the brickwork, but projecting beyond them so as to produce a sharp dark line of zigzag at their junctions. Three of these supplementary stones have unhappily fallen out, so that it is now impossible to determine the full harmony of color in which they were originally arranged. The central one, corresponding to the keystone in a common arch, is, however, most fortunately left, with two lateral ones on the right hand, and one on the left.

§ XXVIII. The keystone, if it may be so called, is of white marble, the lateral voussoirs of purple; and these are the only colored stones in the whole building which are sculptured; but they are sculptured in a way which, more satisfactorily proves that the principle above stated was understood by the builders, than if they had been left blank. The object, observe, was to make the archivolt as rich as possible; eight of the white sculptured marbles were used upon it in juxtaposition. Had the purple marbles been left altogether plain, they would have been out of harmony with the elaboration of the rest. It became necessary to touch them with sculpture as a mere sign of carefulness and finish, but at the same time destroying their colored surface as little as possible. The ornament is merely outlined upon them with a fine incision, as if it had been etched out on their surface preparatory to being carved. In two of them it is composed merely of three concentric lines, parallel with the sides of the triangle; in the third, it is a wreath of beautiful design, which I have drawn of larger size in fig. 2, Plate V., that the reader may see how completely the surface is left undestroyed by the delicate incisions of the chisel, and may compare the method of working with that employed on the white stones, two of which are given in that plate, figs. 4 and 5. The keystone, of which we have not yet spoken, is the only white stone worked with the light incision; its design not being capable of the kind of workmanship given to the floral ornaments, and requiring either to be carved in complete relief, or left as we see it. It is given at fig. 1 of Plate IV. The sun and moon on each side of the cross are, as we shall see in the fifth Chapter, constantly employed on the keystones of Byzantine arches.

§ XXIX. We must not pass without notice the grey and green pieces of marble inserted at the flanks of the arch. For, observe, there was a difficulty in getting the forms of the triangle into anything like reconciliation at this point, and a mediæval artist always delights in a difficulty: instead of concealing it, he boasts of it; and just as we saw above that he directed the eye to the difficulty of filling the expanded sides of the upper band by elongating his triangles, so here, having to put in a piece of stone of awkward shape, he makes that very stone the most conspicuous in the whole arch, on both sides, by using in one case a dark, cold grey; in the other a vigorous green, opposed to the warm red and purple and white of the stones above and beside it. The green and white piece on the right is of a marble, as far as I know, exceedingly rare. I at first thought the white fragments were inlaid, so sharply are they defined upon their ground. They are indeed inlaid, but I believe it is by nature; and that the stone is a calcareous breccia of great mineralogical interest. The white spots are of singular value in giving piquancy to the whole range of more delicate transitional hues above. The effect of the whole is, however, generally injured by the loss of the three large triangles above. I have no doubt they were purple, like those which remain, and that the whole arch was thus one zone of white, relieved on a purple ground, encircled by the scarlet cornices of brick, and the whole chord of color contrasted by the two precious fragments of grey and green at either side.

§ XXX. The two pieces of carved stone inserted at each side of the arch, as seen at the bottom of Plate V., are of different workmanship from the rest; they do not match each other, and form part of the evidence which proves that portions of the church had been brought from the mainland. One bears an inscription, which, as its antiquity is confirmed by the shapelessness of its letters, I was much gratified by not being able to read; but M. Lazari, the intelligent author of the latest and best Venetian guide, with better skill, has given as much of it as remains, thus:

I have printed the letters as they are placed in the inscription, in order that the reader may form some idea of the difficulty of reading such legends when the letters, thus thrown into one heap, are themselves of strange forms, and half worn away; any gaps which at all occur between them coming in the wrong places. There is no doubt, however, as to the reading of this fragment:—“T … Sancte Marie Domini Genetricis et beati Estefani martiri ego indignus et peccator Domenicus T.” On these two initial and final T’s, expanding one into Templum, the other into Torcellanus, M. Lazari founds an ingenious conjecture that the inscription records the elevation of the church under a certain bishop Dominic of Torcello (named in the Altinat Chronicle), who flourished in the middle of the ninth century. If this were so, as the inscription occurs broken off on a fragment inserted scornfully in the present edifice, this edifice must be of the twelfth century, worked with fragments taken from the ruins of that built in the ninth. The two T’s are, however, hardly a foundation large enough to build the church upon, a hundred years before the date assigned to it both by history and tradition (see above, § VIII.): and the reader has yet to be made aware of the principal fact bearing on the question.
