The Ring of the Fisherman (Latin: Anulus piscatoris; Italian: Anello Piscatorio), also known as the Piscatory Ring, is an official part of the regalia worn by the pope, who according to Catholic theology is the head of the Catholic Church and successor of Saint Peter, who was a fisherman by trade.
It used to feature a bas-relief of Peter fishing from a boat, a symbolism derived from the tradition that the apostles were "fishers of men" (Mark 1:17).
[3] Use of the Fisherman's Ring changed during the 15th century when it was used to seal official documents called papal briefs.
[citation needed] This custom was followed after the resignation of Pope Benedict XVI by applying two deep cuts, in the shape of a cross, on the signet with a chisel.
[citation needed] Generally, popes of the past wore episcopal rings in keeping with the fashions of the time.
