Apollo

But being afflicted with a dire disease on account of the murder of Iphitus he went to Delphi and inquired how he might be rid of the disease. As the Pythian priestess answered him not by oracles, he was fain to plunder the temple, and, carrying off the tripod, to institute an oracle of his own. But Apollo fought him, and Zeus threw a thunderbolt between them. When they had thus been parted, Hercules received an oracle, which declared that the remedy for his disease was for him to be sold, and to serve for three years, and to pay compensation for the murder to Eurytus.
