Ordo Romanus Primus is a book written by E.G. Cuthbert F. Atchley in 1905. It is a detailed study of the Roman Catholic liturgy, specifically the first Roman Ordo, which was a guidebook for the celebration of Mass and other sacraments in the early Church. The book explores the history and development of the Ordo, its structure, and the various prayers and rituals associated with it. It also includes translations of the Latin texts and an analysis of their meaning and significance. The author, Atchley, was a prominent Anglican priest and liturgist who converted to Catholicism in 1909, and his book is considered a significant contribution to the study of liturgical history and practice.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
