Of the holy martyrs casket, only the silver plates are now conserved that, acting as a cover, were adapted to the tomb-shaped wooden casket where the relics were kept, always closed and sealed, according to custom, beginning around the 16th century, with regard to the authenticity of the remains of the saints and their conservation and custody. As a result, for their exhibition in cabinets or altars, or to carry them in processions there were sumptuary structures that only had sides and a top, and were slightly longer, wider and higher than the wooden caskets or those made of wood lined with silver. Formally speaking, their architectural structure harks back to the Gothic forms of the 14th century, with the inclusion of the convex lid used during the 16th century; however, the ornamental tendency of crests, knobs, images, floral engraving and stamping, borders of ovolos, laurels, acanthus, pinheads, and pearls may be included in the derivations of the styles typical of the Barcelona workshops of J. Perutxena and F. Via. At different points on the flat surfaces we see the stamp of the Vic workshop, preceded by a cross and set in a rectangle.
