It is not known when this date became the focal point of the Maastricht pilgrimage but in 1289 auxiliary bishop Bonaventura of Liège offered an indulgence to pilgrims visiting the grave of Saint Servatius around this time of the year. The year in which a septennial pilgrimage took place was a Jubilee, which meant that extra indulgences were granted. The majority of pilgrims aimed to earn indulgences by visiting the grave of Saint Servatius, drinking holy water from the cup of Saint Servatius and attending at least one of the daily relics displays. No indulgences could be obtained without going to confession and doing penance. After fulfilling the requirements pilgrims received a pre-printed confessional certificate. A chaplain would fill in the name of the pilgrim and attach the seal of the church. In Maastricht the Collegiate Church of Saint Servatius had the sole right of showing relics in the open air. During the septennial pilgrimage this took place once a day at Vrijthof Square. In the 15th-century so many pilgrims gathered there, that the walls around the square had to be taken down. After celebrating an open-air mass, a selection of the church's relics were shown from the dwarf gallery, the arcaded gallery just below the apse's roof. The dwarf gallery was decorated for the occasion with cloths printed with angels and Saint Servatius' keys. The showing of the relics must have been a theatrical event during which many pilgrims were overcome with emotion. Throughout the ceremony loud cries could be heard. Some pilgrims were sitting on rooftops around Vrijthof to get a better view of the relics and to benefit from their exposure. Many took bread, meat and personal objects with them in order to be blessed by the relics. The relics were shown in four groups. Each group was announced with a formula that started with: "Thou shall be shown...", followed by a brief description of the objects and a prayer. The fixed order was: 1. the sudarium of Saint Servatius (one of the three "heavenly cloths", lost during the Siege of Maastricht of 1579) along with his crozier; 2. the red shroud of Saint Servatius along with his pilgrim's staff; 3. the white cloth that covered the sarcophagus of Saint Servatius, along with his chalice and paten; 4. the reliquary bust of Saint Servatius, the reliquary arm of Saint Thomas and the silver pectoral cross made by Saint Luke for the Virgin Mary.
