Early life Lambert was born around the middle of the eleventh century in
Guînes, possibly belonging to the family of the
counts of Guînes. He began his clerical career possibly in 1068 when he entered the
collegiate church of St Quentin in
Beauvais. Here, Lambert became a student of
canon law, disciple of
Ivo of Chartres and a staunch supporter of the ecclesiastic reform movement. Around 1075, Lambert became
archdeacon of Thérouanne and entered the
collegiate church of Saint-Pierre in Lille. On 10 July 1093, he was chosen as bishop by the clergy of Arras and Saint-Pierre of Lille and he was consecrated by
pope Urban II in March 1094. Arras had previously been part of the
diocese of Cambrai but count
Robert II of Flanders had instigated the founding of the bishopric to weaken the influence of the
emperor in the region.
Bishop After Lamberts election, he summoned many wise men to him to aid him in his task, among them John of Warneton, a
regular canon at
Mont Saint-Éloi Abbey and another former pupil of Ivo of Chartres, who later became
bishop of Thérouanne. Lambert maintained friendships with his former teacher Ivo as well as with Archbishop
Anselm of Canterbury who both esteemed him highly and lent him their political and moral support. When pope Urban II convened the
council of Clermont in 1095, Lambert attended and returned with a copy of its canons. During the four-year absence of most of the Flamish nobles, Lambert and
countess Clemence were able to keep law and order in the county. Together with Clemence, Lambert officiated at the priory of
Watten at the enshrinement of the relics of the
Virgin, St Matthew and St Nicholas that Clemence' husband, Robert II, had received from his sister and her husband Duke
Roger of Apulia. In April 1099, Lambert was in Rome to attend a
synod. This council, which took place between 24 and 30 April, dealt according to Lambert with reforming measures for both the Latin and the Greek Church. Lambert of Arras died on 16 May 1115. ==Legacy==
