1. A bas-relief crowned with pointed trefoil arcading, divided into three compartments, depicting from right to left: St. Martin cutting his mantle, The Crucifixion, and The presentation of the donor to Christ, by John-the-Baptist.
2. The tomb of Jean de Luxembourg, known as the Bastard of St. Pol. This tomb (Hist. Mon.), comprises a bluestone sarcophagus, the front of which is ornamented with five mourners, and each end with three other mourners sheltered under arcades. The covering stone is carved with the statues of Jean de Luxembourg and his wife, Catherine de la Tremouille, in demi-relief. Unfortunately, the upper part of these statues is damaged.
Folleville.
Folleville, with the ruins of its Château and its church, is one of the most interesting places in Picardy, for archæologists. The ruins of the Château (late 14th and early 15th century), situated on a hill, from which there is a very extensive view, are most imposing. The corner towers are round; that in the middle of the northern curtain is over 80 feet high, and is first round, then hexagonal, and finally twelve-sided. In proportion as it rises, it overhangs by means of moulded corbels, which bold design gives it a larger diameter at the top than at the base.
Folleville Chateau
The castle, which began to fall into ruins in the 17th century, was further damaged at the time of the Revolution. It is rich in historical memories. In 1440, it was taken by the English, under Counts Somerset and Talbot, and served for a long time as their headquarters. Under Charles IX, the castle served as a meeting-place for the Protestants. Later, the Leaguers had a garrison there. In February 1592, Henri IV fought a battle in the neighbourhood, against the troops of the Duke of Parma. St. Vincent-de-Paul lived there as tutor to M. de Bondi's children, and it was at Folleville that he inaugurated the missions which were the chief aim of the Congregation founded by him.
