De horis canonicis dicendis by Heinrich von Bitterfeld, 15th century

A treatise on the canonical hours, i.e. the hours that mark the moments of prayer which divide the day of the faithful, regularly observed by the members of the religious orders and often also by laymen. Its author, Henricus von Bitterfeld, originally from Saxony, entered the Dominican Order in Poland and then moved to Prague, where he studied theology and where he ultimately died in c. 1405.

It begins on f. 203r with the words Septies in die laudem dixi tibi. Psalmo 118. Quamvis sit deus semper omnique tempore; it ends on f. 209v with the words qui cum patre et spiritu sancto vivit et regnat deus per infinita secula seculorum. Amen. Explicit compendium hoc.
