Santa Maria del Campidoglio at Cologne, which was founded by Plectrude, wife of Pepin, has the same Lombard galleries running round the apses, and Cunibert's church in its western door shows not only pure Comacine sculpture, but the characteristic lion of Judah between the column and the arch. S. Andrea and S. Pantaleone, both founded in 954 by Bishop Bruno, brother of Otho the Great, were in the same style. This group of buildings all in one city, and all founded under the Emperors who ruled in Italy, surely suggest that when Charlemagne took over the builders for Aix-la-Chapelle, they as usual left their school and _laborerium_ there, and that Otho and his successors in their turn had not far to go for architects. [Illustration: PALAZZO DEL POPOLO AND PALAZZO COMUNALE, TODI. _See pages 137 and 257._] If their churches are not enough, the civil architecture of that epoch also affords proof of Lombard influence in Germany. Compare the windows and style of the ancient dwelling-house at Cologne which Fergusson illustrates, p. 590, with those of any Lombard building whatsoever, from the Palace of King Desiderius in the eighth century to the Bargello of Florence in the thirteenth, and you will find them identical. The only German innovation is in the high gabled roof. Again, compare St. Elizabeth's home, the Castle on the Wartburg, with the ancient Communal Palace at Todi, or at Perugia, or other Lombard building of the twelfth century, and its genesis will at once be seen.[99] Ferd. Pitou, author of the fine monograph on the Cathedral of Strasburg, confirms the presence of Italian builders in Germany, not only in the time of the Carlovingians and the line of Otho, but also in the later times of the Swabian dynasty. He says, when speaking of the works at Strasburg, that "colonies of artisans, chiefly sent from Lombardy and other parts, where church-building was prevalent, accompanied the monks and ecclesiastics who directed the work. These spiritual leaders, however, had all the glory of the buildings up to about the end of the twelfth century, when ogival architecture arose. These Lombard colonies pushed on beyond the Rhine, to the Elbe, the Oder, and the Vistula, and even penetrated to the forests and lands of Sarmatia and Scythia."
