 On 29 March 1897, an official rite was included in the "Roman Pontifical", for which a plenary indulgence was also conceded to the faithful who participated in such rites.The solemn rite of crowning images is contained in the ""Ordo Coronandi Imaginem Beatae Mariae Virginis"", published by the Holy Office on 25 May 1981.Prior to 1989, papal bulls authorising canonical coronations were inscribed manually on parchment.
