This breviary, which contains only the winter part, is dated to the
first half of the 14th century. It is from the diocese of Besançon
(with which Porrentruy was also affiliated), as indicated by
certain saints that appear in the litanies, such as St. Ferreolus
or St. Germanus, the responsories for the Sundays of Advent, as
well as the Holy Triduum.
