O trzech zabytkach muzyczno-liturgicznych z kolekcji Baworowskich przechowywanych w Bibliotece Narodowej
On Three Musical-Liturgical Sources from the Baworowski Collection, Held in the National Library of Poland

Summary/Abstract: My research into three musical-liturgical manuscripts from the Baworowski collection, now kept in the National Library (the gradual PL-Wn 12496 IV and the fragments PL-Wn 12497 IV and PL-Wn 12498 IV) revises our knowledge about them and sheds light on doubts and contradictions resulting from the oldest descriptions of these sources.These three palaeographically different sources from periods very distant from one another turn out to have once formed a single volume. The two fragments as a whole represent a later addition to the gradual, one that was separated from the main section probably during the first half of the nineteenth century. The gradual itself, or rather its main, original part, was compiled around 1250 at the Lubiąż scriptorium for the Cistercian nuns of Trzebnica, possibly as a gift for St Hedwig of Silesia’s daughter Gertrude. Owing to the secularisation of the Silesian monasteries (in 1810), the manuscript was most likely taken from Trzebnica to Wrocław, but it did not end up in the University Library. Instead, like the bulk of the monastic collection, it became the private property of Wrocław-based musician J.T. Mosewius. After his death, with the fragments already separated from the body of the gradual, it joined Wiktor Baworowski’s collection in Lviv, where the three parts of the volume received separate shelf marks. Following the Second World War (in 1945), the gradual and the two fragments arrived at the National Library, already as three separate sources unrelated in any way except for their Lviv provenance.In the light of research, the manuscript, although prepared at the Lubiąż scriptorium, may be called the ‘Trzebnica Gradual’. It belongs to the oldest musical-liturgical sources preserved in Poland and contains the oldest surviving source of the Alleluia verse O felix Hedwigis ( PL-Wn 12486 IV, fol. 1r), as well as one of the oldest sources of the sequence to St Hedwig Consurge jubilans (PL-Wn 12498 IV).
