As the devout among the ancients knew well, nothing spices up a boring sermon like having your own sacrifice pit parked in front of your church.

An ancient Temple of Apollo located amid the ruins of Hierapolis, the "sacred city," in Western Turkey suggests such attractions may have been something of a franchise among temples during the Roman era. Hierapolis was a Greek city famed for its hot springs that the Romans took over in 133 B.C. Apollo, the Sun god, was the chief deity of the city, and Italian researchers from the University of Lecce reveal some of the inner workings of the temple there in the current Journal of Archaeological Science.
The temple's ruins rest on a plateau running along the eastern side of the Menderes River, which itself runs along a geological fault. The fault produced Hierapolis' hot springs, popular with the bath-loving Romans, and also poisonous gases. Those poisonous gases, in this case it seems suffocating quantities of carbon dioxide, appear to be one of the secrets of the Temple of Apollo.
