Pandareus In Greek mythology, Pandareus (Ancient Greek: Πανδάρεως ) was the son of Merops and a nymph. His residence was given as either Ephesus or Miletus. He was said to have been favored by Demeter, who conferred upon him the benefit of never suffering from indigestion, however much food he should eat. At the request of his impious friend, Tantalus, Pandareus stole a bronze (or golden) dog from a temple to Zeus on Crete (the dog, created by Hephaestus, had guarded Zeus during his infancy). According to various sources, he was either turned to stone or fled to Sicily, where he perished together with his wife Harmothoë.
