Quintum sigillum cum aperuisset vidi subtus

As the rubric highlights, this antiphon, in melodic style, is a model: "Quintus concinendi modus", with the purpose of bringing to mind the main features of the melodic contour. The first word of the latin text chosen recalls the number of their tonal group, the fifth. In this case, the text is from Revelation, 6: 9 "Et cum aperuisset sigillum quintum, vidi subtus altare animas interfectorum propter verbum Dei". The order of the wording was modified, starting with "Quintum".
