Chief among the notable accessories and reliques is the monolithic tomb of St. Erkembode, bishop of the one-time see of Therouanne, period 725-37. The sarcophagus itself, dating from the same century, was brought here from the original site. The tomb of St. Omer was restored in the thirteenth century and shows a remarkable sculptured group of Christ, the Virgin, and St. John, called the "Great God of Therouanne." It was saved from the ruin of the church at Therouanne, which was destroyed with the greater part of the town in 1533 by Charles V., in revenge for the "loss of three bishoprics," as history states. At this time the sees of St. Omer and Boulogne were founded. The near-by Palace of Justice, built by Mansart in 1680 and enlarged for its present use in 1840, was the former Episcopal Palace. St. Omer has also two other grand churches, St. Sepulchre, of the fourteenth century, and the ruins of St. Bertin (1326-1520), which, before the Revolution, with St. Ouen at Rouen, and the collegiate church at San Quentin, was reckoned as one of the most beautiful Gothic abbeys in France. To-day it is a magnificent ruin, its huge tower (built in 1431) and portions of the nave and crossing being all that remain. It was considered the finest church in the Low Countries, and for size, purity, and uniformity of style it ranked with the best of its contemporaries. V ST. VAAST D'ARRAS The capital of ancient Flanders was removed from Arras to Ghent when Artois was ceded to France, and thus it was that the city became French, as it were, but slowly, its Low Country traditions and customs clinging closely to it until a late day. The former Cathedral of Notre Dame ranked as a grand example of the ogival style of the fourteenth century, in which it was built, and gave to the city of the "tapestry makers" the distinction of possessing a church composed of much that was best of the architecture of a fast growing art. Such was the mediaeval rank to which the cathedral at Arras had attained. The new Cathedral of St. Vaast, dating from 1755 to 1833, is of the Grecian style of temple building, little suited to the needs of a Christian church. The crucial plan consecrated by catholic usages of centuries is not however wholly abandoned. There is something of a suggestion of the Latin cross in its design, but its abside faces toward the southeast rather than due south, with its principal entrance to the northwest, a sufficiently unusual arrangement, where most French churches are duly orientated, to be remarked, particularly as there is little that can be said in praise of the structure. The interior follows the general plan of the Corinthian order; the windows, neither numerous nor of sufficiently ample dimensions to well serve their purpose, number nine only in the choir, and five on each side of the nave.
