Gerard (tenth century) and St. Poppo (eleventh century); the Abbey of Marchiennes, founded by St. Rictrudes (end of the seventh century); the Abbey of Liessies (eighth century) which, in the sixteenth century, had for abbot Ven. Louis de Blois, author of numerous spiritual writings; the Abbey of St. Sauve de Valenciennes (ninth century), founded in honour of the itinerant bishop St. Sauve (Salvius), martyred in Hainaut at the end of the eighth century; the Abbey of Cysoing, founded about 854 by St. Eberhard, Count of Flanders, Duke of Frioul and son-in-law of Louis the Debonair. Pilgrimages The principal places of pilgrimage are: Notre-Dame de la Treille at Lille, a church dedicated in 1066 by Baldwin V, Count of Flanders, visited by St. Thomas of Canterbury, St. Bernard, and Pope Innocent III, and where, on 14 June 1254, fifty-three cripples were suddenly cured; Notre-Dame de Grâce at Cambrai, containing a picture ascribed to St. Luke; Notre-Dame des Dunes at Dunkerque, where the special object of interest is a statue which, in the beginning of the fifteenth century, was discovered near the castle of Dunkerque; the feast associated with this, 8 September 1793, coincided with the raising of the siege of this city by the Duke of York; Notre-Dame des Miracles at Bourbourg, made famous by a miracle wrought in 1383, an account of which was given by the chronicler Froissart, who was an eyewitness. A Benedictine abbey formerly extant here was converted by Marie Antoinette into a house of noble canonesses. Until a comparatively recent date, the great religious solemnities in the diocese often gave rise to ducasses, sumptuous processions in which giants, huge fishes, devils, and representations of heaven and hell figured prominently. Before the law of 1901 was enforced there were in the diocese Augustinians, English Benedictines, Jesuits, Marists, Dominicans, Franciscans, Lazarists, Redemptorists, Camillians, Brothers of St. Vincent de Paul, and Trappists; the last-named still remain. Numerous local congregations of women are engaged in the schools and among the sick, as, for instance: the Augustinian Nuns (founded in the sixth century, mother-house at Cambrai); the Bernardines of Our Lady of Flines (founded in the thirteenth century); the Daughters of the Infant Jesus (founded in 1824, mother-house at Lille); the Bernardines of Esquernes (founded in 1827); the Sisters of Providence, or of St. Therese (mother-house at Avesnes); the Sisters of Our Lady of Treille (mother-house at Lille), and the Religious
