"Marble Altar Stone And Its Reliquary Tomb - 19th Century "
With its five engraved crosses pattée, it accommodates on its side a large reliquary niche covered with a red wax seal. We can guess, which is quite rare on an altar stone because the size of the niche is usually smaller, that it is an episcopal seal.
