This Celtic Breviary is an attempt to reconstruct what was once the Celtic Breviary. I will be theoretically reconstructing it based on the Antiphonary of Bangor, The Martyrology of Oengus, Rule of St. Columbanus, etc. This is going to be a lengthy project figuring out the Irish Psalter scheme and where to place antiphons, the Irish Kalendar, etc. Suggestions and Volunteers are welcomed!
