This paper discusses hitherto unidentified loose folios of a parchment liturgical and musical book held in the Archdiocesan Archive of Gniezno (Poland), containing the offertory and communion antiphons for the feasts De Trinitate and Corpus Christi. The author provides the codicological description of the leaves (analyzing Latin script, musical notation, ornamentation); identifies the time of their creation (15th century); indicates the type of the liturgical book to which they belong (graduale); seeks a melodic model for them and puts forward provenance hypotheses. He states that the melodics of the antiphons, although closest to the Cistercian tradition, are nevertheless variantly different from the melodic line preserved in foreign and Polish codices. It is possible to narrow down the dating of the leaves thanks to the type of Latin script, the calligraphic ornamentation of the initials and the spelling of certain letters.

格涅兹诺大主教管区档案馆（波兰）的礼仪音乐抄本片段：来源分析和出处假设


本文讨论了格涅兹诺（波兰）总教区档案馆保存的迄今为止未识别的松散的羊皮纸礼拜和音乐书对开本，其中包含圣三节和基督圣体节的献祭和圣餐对歌。作者提供了叶子的编纂学描述（分析拉丁文字、乐谱、装饰）；确定其创作时间（15 世纪）；表明它们所属的礼仪书的类型（渐进式）；为它们寻找旋律模型并提出起源假设。他指出，对经的旋律虽然最接近西多会的传统，但与外国和波兰抄本中保存的旋律线还是有不同的不同。由于拉丁文字的类型、首字母的书法装饰以及某些字母的拼写，可以缩小叶子的年代。
