Apollo sits on a carved ompholos stone—perhaps even a representation of the stone shown in the previous photo—on a coin (shown here) minted in Antioch in 225‒223 B.C. Clearly, the Delphic oracle and its association with Apollo were well known throughout the ancient world in Hellenistic times. By the first century A.D., however, the Pythia’s powers were failing, perhaps because the volume of gases flowing into the adyton had decreased—and by the fourth century, the demise of the oracle was complete.
