The Rite of Church Dedication in Early Medieval Ireland and the Dedication Scheme in the Angers Manuscript 477

The study of the one surviving Irish tract on the consecration of churches (eleventh-century) allows us to identify analogies with the Gallican liturgy. The discovery of a dedication scheme contained in the ninth-century Angers manuscript 477 confirms the features of the Irish rite: the writing of a double Latin alphabet on the floor of the church, the use of maledictory psalms, and the circumambulation of the church while reciting gradual psalms.
