Baring-Gould’s sources: Belgian Martyrologies. S. Landoald is venerated especially at Ghent. Also Roman and Gallican Martyrologies. The translation of S. Landoald is commemorated on Dec. 1st, and the elevation on June 13th. The original Acts were lost in 954, and by order of Notker, B. of Liege, new ones were compiled in 981, by one Herdger, abbot of Lobie, who died 1007.

S. Amandus having resigned the see of Maestricht [a bishop’s “see” is his diocese, named from his seat (Latin sedes)] into the hands of S. Remacle, to resume his first vocation of mission work in the Low Countries, went to Rome to obtain the approval of his design by pope Martin. The pope not only approved of it, but gave him Landoald, a priest of the Roman Church, of Lombard family, to accompany and assist him in his work. S. Amandus was also joined by the deacon Amantius. They left Rome, and after visiting some of the monasteries of France, arrived in the country between the Meuse and the Scheldt, where S. Remacle met S. Amandus, and persuaded him to allow him to keep Landoald with him to assist him in the work of evangelising his diocese. Landoald had a large field for the exercise of his zeal in the diocese of Maestricht, only partially converted to the faith. A rich man named Aper gave him a piece of land at Wintershoven, on the river Herck, to the west of Maestricht, where he built a church, which he dedicated to S. Peter, in 659. Landoald continued his labours under S. Theodard, the successor of S. Remacle, making Wintershoven his head-quarters, and sending from time to time one of his little community to Maestricht to beg. One of his disciples, Adrian by name, was returning from his quest of alms, when he was waylaid by some robbers, and murdered. S. Landoald did not long survive him, and there is reason to believe that he died before S. Lambert succeeded, in the see of Maestricht, to S. Theodard, who was martyred in 668. He was buried in the church of Wintershoven, but his body was taken up in 735, and transported into Maestricht, but from fear of the Normans it was concealed, and taken up again along with the bodies of S. Amantius and S. Adrian, by Euraculus, bishop of Liége, but they were claimed by the monks of S. Bavo, at Ghent, who were proprietors of Wintershoven, and the bodies were translated to Ghent in 980.
