Among the fragments of pre-Christian sepulchral art on display in the Sala del Paradiso, this quadrangular funerary cippus stands out, decorated in bas-relief on three sides. It is an Etruscan cippus made of pietra fetida, a type of limestone typical of the Chiusi area (province of Siena), which owes its name to the strong sulfurous odor it emits when worked, due to its high sulfur content. These characteristics suggest that the artifact likely originates from excavations in the necropolis of that region.

The cippus was discovered in the cellar of the Prepositura dell’Opera, though the circumstances of its arrival in the Museum's collections remain unknown.

Each of the three decorated sides features scenes of funerary rites, performed by triads of figures shown truncated at the waist. On the front, two male figures are depicted with torsos facing forward and heads in profile, dressed in a fine tunic of Greek derivation and the characteristic draped cloak known as the tebenna, both facing toward a central diaulos player (a double-reed flute). On one of the lateral sides, two male dancers flank a female figure, with the man on her left gently touching her chin. On the other side, a cithara player (or kitharōidos) occupies the center, accompanied by two additional figures.
