We were especially interested in the temple because the Blue Guide reports that "During the excavation, work was impeded considerably by noxious gas which seeped from the foundations. It was found that this gas originated in the Plutonium...a sanctuary dedicated to Pluto, the god of the underworld." The poisonous gas emanating from the Plutonium was well-known in antiquity. In the late 2nd or early 3rd century the Roman historian, Dio Cassius, "tested its lethal properties on birds" and "remarked also on the apparent immunity enjoyed by eunuchs" (Blue Guide 277). After what the guide books had to say, I imagined the Plutonium would be quite the tourist attraction, but the site is now overgrown with grass and is not exactly well-marked. The Lonely Guide comments that the gas "is still deadly poisonous. Before the grate was installed there were several fatalities among those with more curiosity than sense." Suitably warned, I took this picture using my camera's telephoto lens.For pictures, see the original post from my Turkey Travelogue.
Whether or not there is anything new to report, I'm really looking forward to returning to Hierapolis with the Briercrest Turkey/Greece study tour next month.
