Along one wall is the Plutonium, meaning the “Gate to the realm of Hades/Pluto.” It got its name because it’s actually a small cave that leads to a volcanic fissure, which emits deadly amounts of carbon dioxide. Priests of the goddess Cybele managed the shrine here and learned the trick of crawling on the floor to inhale pockets of oxygen (C02 is lighter and rises.) When the priests returned from the cave unharmed, they became a testament to Cybele’s resurrectional capabilities. Smart businessmen, these priests sold birds and small animals to worshippers, who could then test the suffocating powers of the fumes on their new pets. Many tourists have died climbing up to peer into the cave, so we kept a healthy distance away. Pardon the bad book photo; mine did not turn out well.
