The principal stained-glass windows in the north aisle are: in the first window beginning at the great doorway, the battle of "las Novas de Tolosa" won by the Spaniards over the Moors in the thirteenth century; donors; patrons; the transfiguration. The next window deals with the death and coronation of the Virgin and represents the donors (_the panel reproduced on p. 205 belongs to this window_). The third window is dedicated to the life of Saint Anne and the Virgin; the fourth represents the Adoration, the Massacre of the Innocents, the Flight into Egypt, the last Supper; the fifth, the Passion; the sixth, the Ascension, the Virgin, Christ crowned; patrons and donors. In the south aisle, the first window represents the life of Saint James, the Transfiguration, Christ appearing to his disciples; the second, scenes from the life of the Virgin; the third, the Last Supper; the fourth, the life of the Virgin and the legend of Saint James. [Illustration: APSE OF NOTRE-DAME] As in all the churches in the neighbourhood, mortuary stones are numerous.

In the ninth century it was placed under the patronage of Saint Alpin, when the body of this Bishop of Châlons was transported there. Saint Alpin, like Saint Loup at Troyes, and Saint Geneviève in Paris, went out to confront Attila, and succeeded in obtaining a promise that the town should be spared by the "Scourge of God." A sixteenth century stained-glass window (the first in the south aisle) commemorates this episode in the life of the saint (photograph below). The bishop, his mitre on his head, the cross in his hand, surrounded by clergy and laymen, is pleading the cause of the town before the King of the Huns, seated on a sumptuous throne amidst his warriors. At the foot of the throne are captives in chains. [Illustration: SAINT ALPIN BEFORE ATTILA (sixteenth century stained glass)] As we have seen on p. 198, fifteen centuries later the same scene was enacted. In September, 1914, Mgr. Tissier, Saint Alpin's successor in the bishopric of Châlons, was obliged to plead for his town with the invaders. The Church of Saint Alpin was reconstructed and enlarged in the twelfth century. From this period date the west front (see above), the nave and its side aisles. The north branch of the transept belongs to the fourteenth century, the south branch to the sixteenth. The apse goes back to the sixteenth century, as does the tower surmounting the middle of the transept, also the chapels of the side aisles. At the same period, doors leading into each aisle were pierced on either side of the doorway of the West Front.
