The Regional Museum and Gallery in Most has provided access to a manuscript referred to as the Unfortunate Hymnal from Most from its collections. The codex contains hymns for the Mass, but also for the Liturgy of the Hours. It was made for the brotherhood of Corpus Christi and the Virgin Mary at the church of the Church of the Assumption of the Virgin Mary in Most. Based on a contract from 27 July 1537, the town of Most commissioned the making of the codex to the scribe and illuminator Jakub from Pilsen. The manuscript was to be completed by 15 October 1538. In fact, however, it was not handed over to the users until May 1544. It has been damaged by the cutting out of a number of leaves of the manuscript, including all with illuminated decoration.
