The nave, decked with a copper roof, abounds no less in decoration than the front. It has large ogive windows adorned with _rosaces_; at the place where the buttresses, equally carved with _rosaces_, join the counterforts or pillars, they have at their tops fine clochetoons; a great many statues and grotesque figures of heads complete the ornaments of this part of the church. Two galleries, one under the windows, the other below the clochetoons of the counterforts, lead from the towers to the cross-aisle. This, as we have already said, is still byzantine in several parts of it. The southern porch, formed by two semi-circular doors made evidently at one of the remotest periods of the Cathedral, is adorned with bas-reliefs and statues; according to tradition, it is reported that two of these statues are the work of Sabina of Steinbach. One is a woman in a triumphal posture holding in her hands a communion cup and a cross; she is the symbol of the church that vanquished the synagogue; the other, a symbol of the latter, is a woman looking down, blindfolded and leaning with pain on a broken spear, whilst the laws of the twelve tables drop from her left hand. On the parvis before this porch is erected, on the left, the statue of Sabina herself, and on the right, the statue of Erwin of Steinbach, both due to the chisel of Mr. Grass. The wall of the upper tier has openings for several windows of an ogive form, above which a gallery runs all along; two round-windows take up the third tier. The northern portion of the cross-aisle has more generally preserved the byzantine manner than that we have just spoken of; however, this intermixture with the gothic style denounces latter renovations. The ancient porch, the remains of very old constructions, is masked by a fore-front that belongs to the last period of the gothic art, and which was built in 1494 by James of Landshut; this new porch (_porch of St. Laurence_), though handsome in its _ensemble_, is wanting in that noble simplicity and purity of taste that distinguishes the other parts of the Cathedral; it is overloaded with ornaments, and its statues have a stiffness that is found nowhere else. The octangular dome over the chancel is also of the byzantine era; however, it has been renewed in several parts. In the place of the deformed cupola, destroyed by the fire of 1870, a handsome pyramid has been erected in the year 1878, after the plans of Mr. Klotz, architect of the Cathedral. Up to 1772 the lower part of the lateral fronts of the church was disfigured by paltry decayed houses; the same year they were pulled down and in their places the present porticos were built, which are not wanting in elegance: the shops and stalls that formerly obstructed in so disgraceful a manner the access to the nave, have also disappeared; and the porches have been repaired with a great amount of good taste.
