The pax was also a reliquary, if of a lower grade, since it contained a relief medallion consecrated by Pope Alexander VI, which depicts the Agnus Dei.
After her death, her husband Anton Theodor Brentano donated the pax to the Bishop of Limburg, Peter Joseph Blum.
Blum left the pax to the Limburg Cathedral treasury, as "Donation of Josephine and Anton Brentano."
The relief medallion of the Agnus Dei had been lost by this point, but it was replaced with a new one, blessed by Pope Pius VIII.
The decoration thus refers closely to the original recipient, Abbot Martin Rifflinck, who shared his name with the former and was especially devoted to the latter.
