A homogeneous set of large liturgical manuscripts – antiphonaries and graduals from the collections of the Strahov Library has been digitised. Individual codices come from the period between the end of the 15th century and the 17th century. The oldest of them is the gradual of Friars Minor DA I 4, probably of Silesian origin, which was later owned by the monastery in Znojmo. Gradual DA I 5 was made directly in the Strahov monastery at the beginning of the 17th century. It was written by the Premonstratensian scribe Jan Václav Šícha and commissioned by the abbot of the Strahov monastery Johann Lohel. The other codices (DA I 1–3) are of foreign origin. Like DA I 5, they are quite richly decorated, but the quality of the illuminations is not considered as high.
