Until the reform of the liturgy after the Second Vatican Council, Easter consisted of the Triduum Sacrum, which included the days from Maundy Thursday to Holy Saturday, Resurrection Sunday and the Paschal Octave. The preparation was the period of the Passion of the Lord, starting two weeks before Easter, and especially the first days of Holy Week. Piety, and to a large extent also liturgy. There are few surviving documents detailing the course of this liturgy, and those we have are generally late and consolidate the point of arrival of Baroque liturgical creativity. This does not mean that all the elements of this liturgy that no longer exist today, especially those that have an almost theatrical character, were introduced only in the Baroque era. In the archives of the Benedictine nuns of Vilnius (currently in Żarnowiec) there is a manuscript from 1807, No. F 12, entitled: "Clerical ceremony of church rites according to the rule and custom of the order of Father St. Benedict, for the reverend nuns of the Nieśwież monastery [...]". This manuscript, which is a copy of an older ceremonial master, provides the entire liturgical practice of the Nieśwież monastery, adapted to local spatial conditions, the possibilities of the community, the needs of the surroundings, and even the climate and the local plagues related to it.
