### codices, hymn, csízió (calendar), Hora - hora book
codices Bigger, book-size, hand-written products of old literature. Most of them are religious books. The majority of them were written in Latin, but from the 15th century Hungarian codices also appeared. ASH Hymn Hymns are songs praising God. They were introduced to Latin liturgy by St Ambrose († 397), whose 12 hymns also survived. As a liturgical genre it belongs to the songs of the office. The structure of verses are identical within a verse, but the last verse is a credo about the Holy Trinity, called doxology. EM Csízió (calendar) The 'csízió' is a calendar with poems, in which each month is represented by a two-line poem (so a year consists of 24 lines). Each syllable of the text represents a day. The peoms were compiled of the feasts of the month and the names of the saints or the first syllables of these. The Hungarian word 'csízió' originates from the Latin; it comes from the expression circumcisio Domini (the Lord's circumcision), which referred to the 1st of January. ASH Hora, book of hours Hora meant a special time, an hour during the day when the monks had to say obligatory prayers and offices. It originates from the Latin word 'hora'; and is the Latin equivalent of the Hungarian word 'óra" [hour]. The book of hours was the prayer book which contained these prayers and offices. ASH
