This window belongs to the thirteenth century, but it is probably modelled on an earlier one of which there is mention. Like the three twelfth-century windows of the west, and especially the southernmost of these three, it is strikingly Byzantine in character. The Miracle at the Marriage of Cana and the Temptations of Christ fill the lower part of the light.
In the case of the remaining windows the evidence of design is less obvious than in that of the groups with which we have dealt. Much was evidently left to the caprice of the donors, who usually chose to represent the lives, the struggles or the martyrdoms of their patron saints. Thus the episodes of the life of a local priest, S. Laumer, are recorded in a series of medallions, just as one of his miracles is related in stone in the south porch. The storied window suggests at once practically all that we know of him. Some time in the seventh century, it is said, he kept his father’s sheep near Chartres, but afterwards, having learned his letters, he was ordained priest and entered a monastery. But he longed for a life of prayer and solitude, and fled to the forest where he hoped none would follow him. It was vain; disciples, hearing of his sanctity and the miracles he wrought, flocked to him. Again he fled and settled in the woods near Dreux. But his cell of green leaves and wattles soon became the centre of a colony of monks, so that he was fain to recognise the call of God and to build a monastery there. Of the miracles recorded as wrought by him there is one characteristic of his gentle individuality. During the night some robbers stole a cow belonging to the monks. The brethren were in despair. The robbers, however, lost their way in the tangled forest. They wandered all night and all next day, unable to discover the road. At last, as evening settled in, they saw the darkness of the forest lighten, and, still driving the cow, they came out upon the clearing of the monastery. S. Laumer himself stood before them. They fell at his feet, asking his pardon and imploring him to direct them aright. He raised them and said, ‘I thank you, kind friends, for finding and bringing back to me my strayed cow. You must be very tired and hungry. Follow me.’ They followed him into his hut and he set before them such food and drink as he had, and they ate and drank and were refreshed. Then he set them on their right road, and they departed--but without the cow.
