On the first folio of the fragment parts of the mass of the first Sunday in the octave of Christmas, and the octave (Circumcisio Domini), on the second folio parts of the mass of the second Sunday after Epiphany were preserved. From the arrangement of the second fragment’s two sides, we can deduce, that the initial gradual alternately contained sections of the sanctoral and the temporal, hence on the verso of the f. 2 the Introit (Os justi) of a saint (presumably Felix of Nola) of the period post Epiphany is legible. Besides the arrangement typical to early sources, the presence of the Offertory-verse (Eructavit cor meum) is also a trait of earliness.
