The fragile Agnus Dei (or a fragment of it) was often enclosed in a pouch of cloth or leather, that was then embroidered or decorated with lace. This work of devotion was usually entrusted to cloistered nuns. Carrying an Agnus Dei provided 'Immunities' including Protection against floods, thunderstorms and wind-storms, Aid toward atonement, Security against a sudden and unexpected death, Guard against the wiles of the devil and the snares of witchcraft etc. The tradition of the Vatican consecrating and distributing Agnus Dei may have started as early as the 6c., was well established in the 9c., and was last performed in 1964.
