Definition of term:: Horae


  • Book of Hours. "Manuscript or printed collections of litanies, prayers, etc., for private devotional use at the canonical offices of the Roman Church. Variations of detail between one diocese and another are indicated by such phrases as ‘Horæ of the Use of Rouen’, or ‘a Book of Hours of the Sarum Use’.The output of manuscript Horæ, during the 14th and 15th centuries particularly, must have been immense. The majority of printed examples derive from the years between 1490 and 1520, with Paris as the most active centre of production." (John Carter)
