The processional mace is made up of a polygonal shaft with reinforced edges and an architectural body with two orders of single-lancet windows with engraved bricks. The apical termination depicts the uprooted tree, the coat of arms of the Giudicato d'Arborea and the Diocese. The shaft features the brand with the assay serpentine several times. The characteristics of the brand and the shape of the artefact date the artefact to the sixteenth century. It is assumed that the artefact was made by the famous Cagliari silversmith Giovanni Mameli: the technical characteristics and the shape of the cross recall other artefacts made by him in the churches of S. Eulalia in Cagliari (1576) and in the parish churches of Mogoro and Muravera (1601), in particular the graft and the temple knot (niches, statuettes, finishing merlons)
