Only three such manuscripts have been offered at auction in the past seventy years (RareBookHub). The manuscript consists of the first volume, for the month of January, of the 'Menaion' (i.e. 'month'). The full set of 12 liturgical books, subdivided by month is usually bound separately, gathering liturgical texts such as hymns, kanones, synaxaria and lections for saint's day or observance of a holy event falling on a fixed date in the Byzantine church calendar, which started in September. The text begins a couple of paragraphs into January 1 and ends on January 30. This suggests there were probably at least one or two additional leaves, now lost, at beginning and end. A selected comparison to received versions of the 'Menaion' shows that, whilst the skeleton texts are present, there appear to be frequent variations, a study of which may help identify local saints and a specific place of production.
