459. Tower of Sta. Maria in Cosmedin. (From Gutensohn and Knapp.)
The tower of St. Apollinare in Classe, above referred to, the most perfect of those of Ravenna, is a simple brick tower (see Woodcut No. [412]), nine storeys in height, the lower windows being narrow single openings; above there are two, and the three upper storeys are adorned with four windows of three lights each.
In Rome, as far as we know, the first tower attached to a church was that said to have been built by Pope Adrian I. in front of the atrium of St. Peter’s; but there are no examples now existing in Rome which can be said to be earlier than the 11th century, and that date applies only to the lower portion of them. In the 12th and 13th centuries they became common, and we find them attached to the churches of S. Lorenzo without the walls, S. Croce in Gerusalemme, SS. Giovanni e Paolo, S. Giorgio in Velabro (13th century), and others. All these are square in plan and extremely similar in design, no improvement and scarcely any change having taken place between the first and the last, as if the form were an old and established one when we find it first adopted. That attached to Sta. Maria in Cosmedin (Woodcut No. [459]) is perhaps one of the best and most complete. Its dimensions are small, its breadth being little more than 15 ft., and its height only 110; but notwithstanding this there is great dignity in the design, and, in a city where buildings are not generally tall, its height is sufficient to give it prominence without overpowering other objects,—a characteristic which renders these Roman towers not only beautiful structures in themselves, but appropriate ornaments to the buildings to which they are attached.
The chief interest of these towers is derived from the numerous progeny to which they gave birth: for though there is scarcely an instance of a square Romanesque tower beyond the walls of Rome during the period in which this style flourished, the form was seized upon with avidity by the Gothic architects in all the countries of Europe; and whether as a detached campanile (as in Italy), or as an integral part of the building (as we soon find it employed on this side of the Alps), it forms the most prominent, and perhaps also the most beautiful, feature in the aspiring architecture of the Middle Ages.
There is certainly no architectural feature which the Gothic architects can so justly call their own as the towers and spires which in the Middle Ages were so favourite, so indispensable a part of their churches and other edifices, becoming in fact as necessary parts of the external design as the vaults were of the internal decoration of the building.
It is true, as before remarked, that we neither know where they were first invented, nor even where they were first applied to Christian churches—those of Rome and Ravenna being evidently not the earliest examples; nor have they any features which betray their origin—at least none have yet been pointed out, though it is not impossible that a closer examination would bring some such to light. They certainly are as little classical, in form or details, as anything that can well be conceived; and belong to an undefined Romanesque style.
Those of which we have already spoken are all church-towers—campaniles or bell-towers attached to churches. But this exclusive distinction by no means applies to the Gothic towers. The tower of St. Mark at Venice, for instance, and the Toraccio at Cremona, are evidently civic monuments, like the belfries of the Low Countries—symbols of communal power wholly distinct from the church, their proximity to which seems only to arise from the fact of all the principal buildings being grouped together. This is certainly the case with a large class of very ugly buildings in Italy, such as those attached to the town-halls of Florence and Siena, or the famous Asinelli and Garisenda towers at Bologna. They are merely tall square brick towers, with a machicolated balcony at the top, but possessing no more architectural design than the chimney of a cotton factory. Originally, when lower, they may have been towers of defence, but afterwards became mere symbols of power.
A third class, and by far the most numerous, of these buildings are undoubtedly ecclesiastical erections; they are either actually attached to the churches, or so placed with regard to them as to leave no doubt on the matter. There is not, however, I believe, in all Italy a single example of a tower or towers forming, as on this side of the Alps, an integral part of the design.
Sometimes they stand detached, but more generally are connected with some angle of the building, the favourite position being the western angle of the southern transept. Occasionally we find one tower placed at the angle of the façade, but this is seldom the case when the tower and the church are of the same age. It is so in the cathedral at Lucca, and San Ambrogio at Milan; in the latter of which a second tower has been added more recently to balance the older one. It does also happen as in the instance of Novara, before quoted (Woodcut No. [443]), that two towers are actually parts of the original design; this, however, is certainly the exception, not the rule.
