مريم العذراء
Saint Evrard, at Cysoing, had a chaplain named Walgaire. They (Evrard and Gisèle) decided to found a monastery at Cysoing. The project was long and difficult, and was not complete at the time of Evrard's or Gisèle's deaths. The monastery was initially made in honor of Saint Saveur and Mary (mother of Jesus). The religious lived there under canon law in a community with all the rigors of the cloister. Their special function was singing solemnly in the church. They maintained public prayer. Saint Evrard was known to enjoy singing with the choir. After his later campaigns in the defense of Italy, the remains of Pope Callixtus I were re-interred in the Abbey at Cysoing.
