Suger wrote inscriptions for his abbey windows to make their symbolism clearer. Owing to the vicissitudes of seven hundred years, few of the St. Denis lights have survived. Four are now reset in the central apse chapel and in that to its north. In a medallion at the base of one of these windows Suger himself is represented holding a scroll bearing his name. The medallion figures are of the hieratic Byzantine type. Every window has a closely woven pattern; each losenge has its own border, and a rich jeweled border surrounds the whole lancet. Bracing bars of iron run straight across the pictured story. Slowly, with infinite patience, worked those old XII-century artists, and never has their handicraft been surpassed as sheer splendor of ornamentation.
After three years and three months of passionate work, the choir of St. Denis was finished, and on June 11, 1144, the dedication day, the relics were installed. That date, forever memorable in the annals of architecture, may be called the consecration of the national art. At the ceremony assisted Louis VII with his queen, Aliénor of Aquitaine, whose strange destiny was to make her patroness of that entirely different phase of Gothic called the Plantagenet school. The chief barons were present at the dedication, as well as five archbishops and some fourteen bishops. They looked and wondered, and not a few of them returned home to imitate. The bishops of Noyon and Senlis hastened to rebuild their cathedrals in the new way, and some of Suger's masons passed into the service of the former prelate. Bishop Geoffrey de Lèves went back to Chartres to build the most beautiful tower in the world, and the sculptors who had made Suger's western portals (now no longer extant) worked on the three west doors of Chartres.
On the day of St. Denis' dedication, Abbot Suger, small and frail in person, but towering in personality, was honored on every side. When the abbot of great Cluny, Peter the Venerable, passed from the marvels of the new church to Suger's narrow cell, he cried out in honest distress: "This man condemns us all. He builds, not for himself, but for God alone!"
Though the last half of Suger's life was an example of monastic simplicity, not always had he been content with a monk's cell. Perhaps because of his conversion midway in life, he appeals to us in a more human way. Not that he was converted from evil doings; his purpose always was high. But in his position as St. Denis' abbot, as a powerful feudal lord, he lived sumptuously, according to the accepted standards of the time. He mixed freely in the world; he directed state affairs for the king to whom he was devoted; he went on embassies; he even led armies. In 1124, when an irate German emperor was marching on Rheims, which he had vowed to destroy, Suger in person led against him some ten thousand of his abbey's retainers. That was the first time the oriflamme of St. Denis was carried as the national emblem.[32] Suger had grown up in the secular atmosphere of the Royal Abbey, and took its worldliness as a matter of course.
