‪If you are in the area it's worth a brief detour to visit this fascinating site. Do not climb over the viewing barrier or go near the bubbling sulfurous water. In Roman mythology, Mefitis (or Mephitis; Mefite in Italian) was the late personification of the poisonous gases emitted from the ground in swamps and volcanic vapors. "Mephitic", derived from Mefitis, is now an adjective in the English language meaning "offensive in odour"; "noxious"; and "poisonous." In Italian, a mefite is also a solfatara or fumarole (i.e., a gaseous fissure) associated with the Roman Goddess Mefitis. The feature giving rise to this term, the Solfatara volcano, is located in Italy along the Via Appia between Rome and Brindisi. There, the ancient Romans would rest on their travels and pay homage to the goddess by performing animal sacrifices using the fissure's deadly gases. Today, it lies near the village of Rocca San Felice in the province of Avellino.‬

‪If you are nearby you have to come and see it. It is really strange as you can smell the gas coming from the center of the earth!! It is an amazing experience !! ‬
