Rock Crystal and Gold Agnus Dei Late 16th, early 17th century Case made in Milan Agnus Dei in wax from the Vatican Among the most significant religious artifacts of the Renaissance, the Agnus Dei medallion exemplifies the height of Catholic devotional culture. Believed to hold sacramental blessings and even miraculous power, these sacred wax objects were crafted from the melted remains of the Paschal candle used in Rome and personally blessed by the Pope. Their rarity was compounded by their fragility—few survived intact, making them among the most coveted religious items of their time. This extraordinary example, dating from the late 16th to early 17th century, defied the odds of survival.

It is the only known example outside of a museum, with possibly two others in institutional collections. Made for a patron of exceptional wealth, this late Renaissance masterpiece marries religious significance with extraordinary craftsmanship.

Two elegant gold scrolls wrap around back-to-back dog muzzles at the top, crowned by an enamel-decorated knob and suspension ring—creating a devotional object of unparalleled artistic refinement. The fragile composition of Agnus Dei medallions meant that most were easily damaged—cracking, collecting dirt or crumbling over time. Their pristine whiteness held such sacred significance that in 1572, Pope Gregory XIII issued a Papal Bull...
