Excavations in the cathedral of Tournai revealed two sepultures, which were identified by excavators as those bishops because their special location cathedral. One burial was assigned to Baldwin I, who died AD 1068, (1) a ring with inscription “BAL” found and (2) funeral stone text present on top grave mentioning name Baldewinus. The second probably belongs Radbot II, successor 1098. Both burials contained textiles (silk), skeleton, wooden pastoral staff, human hair still skull what presumed be II. All protein-containing materials degraded and/or contaminated. Standard sample pretreatment methods not able remove all contaminants. Single double cross-flow nanofiltration hydrolyzed performed. quality for radiocarbon dating improved 14 C data interesting surprising results. dates staff permeate femur confirm that skeleton tomb belong bishop I. indicate may indeed younger silk samples postburial disturbance site during 12th–13th century.
