The feast of Ss. Cyril and Methodius belongs to the well-regarded religious and national holidays. The apostles of the Slavs initiated various forms of cultural life, closely connected with that of the church. The legends appearing after the death of Cyril and Methodius testify to a canonized esteem which did not officially exist after the fall of Great Moravia, but found favourable conditions in Bulgaria and the Czech lands. The Cyril-Methodius veneration was restored in Bohemia and Moravia in the 14th century and the first medieval prayers to them were created. The article discusses how the Liturgy of Hours in honour of Ss. Cyril and Methodius has undergone several stages of development until its modern version has been formed.
