เครื่องรางอักนุส เดอี (ลูกแกะของพระเจ้า)Agnus DeiAgnus Dei

The oldest sacramental in the Roman Church is a lump of recycled candle.

Herbert Thurston, writing the Catholic Encyclopedia entry in 1907, puts the ninth-century practice like this: the archdeacon made the Agnus Deis early on Holy Saturday morning out of clean wax mixed with chrism, and handed them out to the people on the Saturday following. What changed later is who does the blessing. The great consecration of Agnus Deis takes place only in the first year of a pontificate and every seventh year after it — a rule Thurston says was still followed in 1907 — and it is the pope who performs it. That schedule is the whole economics of the object: a papal Agnus Dei is scarce by design.

The claims Thurston records are stated plainly and stated wide: protection "from all malign influences", and specifically "perils from storm and pestilence, from fire and flood, and also of the dangers to which women are exposed in childbirth". He also records the reported results rather than asserting them: "Fires are said to have been extinguished, and floods stayed." That is the exact grammar this atlas uses, arrived at independently and a century earlier.

The Agnus Dei is also where the Roman habit of blessing an object and attaching indulgences to it got started, or at least where the Catholic Encyclopedia says it got started. Writing on devotional medals, the same encyclopedia dates the sixteenth-century practice of giving a papal blessing to medals — and then enriching them with indulgences — to a usage "long previously in vogue in the case of Agnus Dei (discs of wax impressed with the figure of a lamb and blessed at stated seasons by the Pope, which could be worn suspended round the neck)". Inference — every struck medal later in this batch descends from this wax disc, procedurally if not physically.

The Church's line between a sacramental and an amulet runs straight through it. A sacramental, by the Catholic Church's own definition, is a sacred sign that works by the Church's prayer and "does not confer the grace of the Holy Spirit in the way that the sacraments do"; it disposes a person to receive grace rather than acting on its own. Set that beside a wax disc credited with stopping a flood and the tension is not hypothetical. The 2001 Directory on Popular Piety and the Liturgy names the boundary in general terms: popular piety "may never incorporate rites permeated by magic, superstition, animism, vendettas or sexual connotations", and elsewhere it warns against keeping blessed palms as amulets or for therapeutic or magical purposes. Both positions are the Church's. This atlas prints both and settles neither.

Cast from the remains of the previous year's paschal candle, mixed with chrism, impressed with the lamb, and blessed by the pope in the first year of his pontificate and every seventh year after. Distributed by the pontiff, often through envoys, and usually in a case or a cloth mount when worn. It is not renewed on a cycle and it is not burnt at retirement; it is kept.

This project has read nothing dated later than the 1907 encyclopedia entry on whether the seven-year consecration still happens, and it will not guess. Old Agnus Deis survive in Catholic households, in reliquary frames, and in museum and papal-artefact collections. That is what can be said: the object exists, its present manufacture is unverified here, and a reader who needs to know should ask a diocese.
