That it had a tower in 1130 is a certain fact; for K[oe]nigscoven speaks of its destruction by fire in the course of that year; successive fires, in 1140, 1150, 1176 also materially injured the beautiful edifice; besides, the continual wars and tumultuous commotions of the time prevented the bishops from undertaking essential repairs. It appears that these causes, by degrees, brought on the complete ruin of bishop Wernher's constructions; for unquestionably the part included between the nave and the two towers dates but from the thirteenth century, and cannot have been begun before the middle of it. What remained of the old church was pulled down at that time and a new and more spacious edifice was erected, built in the style then spreading over all Europe. Considering the immense size of this monument, it is easy to imagine that the work went on but slowly, and an old chronicle mentions that on the 7th September 1275 they finished the middle part of the superior arch-roofs, with the exception of the towers in front. By whom these labours were directed is altogether unknown. It was bishop Conrad of Lichtenberg who undertook to rebuild the parts that were still in a state of ruin and thus at last to accomplish this great work of the Cathedral[1]. [1] "... _Ipsa ecclesia in meliorum statuum reedificetur_ ..." (See a charter of bishop Conrad of Lichtenberg, published by M. L. SPACE 1841, p. 6). In order to execute this design, he published indulgences all over the country; and after collecting large sums of money in the town, he applied to the ecclesiastics of his diocese, asking their own gifts and offerings as well as those of the faithful under their direction; in a synod held in the diocese, the clergy agreed to give up, during four years, a fourth part of their revenues. Conrad entrusted the direction of this work to Master Erwin of Steinbach, who, according to some old documents, was a native of Mayence. This great architect began by rebuilding the nave, the arch-roofs of which were completed in 1275. Then he commenced the facade of the church and its towers from a plan so bold and sublime that the conception of it places Erwin for ever at the head of the architects of the middle age[1]. In 1276 they laid the foundation of the northern tower; to consecrate the spot, the bishop walked solemnly round it, then took a trowel in his hand and thrust it into the ground, as a sign for beginning the work. They relate that a quarrel having occured between two workmen who both wished to work with the trowel the bishop had held in his hand, one of them was killed. This murder was considered as a very bad omen; Conrad ordered their labour to be suspended for nine days; they were only resumed after he had consecrated the place anew. The following year, on saint Urban's day (25th May), Conrad himself laid the first stone of the tower. In the midst of his warfares, this bishop always entertained much
