The liturgical content of this manuscript corresponds to that in
use among the Carthusians. The church consecration festival listed
in the Proprium de Sanctis between the feast days on the 4th and
the 23rd of April probably refers to the 18th of April, when this
holiday was celebrated at La Lance. This observation suggests that
the manuscript was created in the Carthusian Monastery La Lance
(Canton of Vaud). Several ex-libris can be dated around 1500 and
confirm the presence of this codex in the monastery, at least until
its dissolution in 1538. Then the manuscript was passed on to the
Carthusian Monastery Part-Dieu in the Canton of Fribourg. Recently
the manuscript was restored and the old binding was replaced.
