Apollo in the islands. Apollo's sister Artemis, who was the Greek goddess of hunting, is identified with Britomartis (Diktynna), the Minoan "Mistress of the animals". In her earliest depictions she is accompanied by the "Mister of the animals", a male god of hunting who had the bow as his attribute. His original name is unknown, but it seems that he was absorbed by the more popular Apollo, who stood by the virgin "Mistress of the Animals", becoming her brother. The old oracles in Delphi seem to be connected with a local tradition of the priesthood, and there is not clear evidence
The Trials of Apollo own robots. They then navigate the maze with the help of Piper McLean and Jason Grace and find defeat Medea, the sorceress who was working with the emperor. Around this time Caligula (the emperor) kills Jason Grace. The next day, Grover, Meg and Apollo using Caligula's shoes walk the Labyrinth. They free Herophile and discover a new prophecy: “Apollo faces death in Tarquin’s tomb unless the doorway to the soundless god is opened by...”. They also discover that they need help from ‘Bellona’s daughter’, Reyna, the praetor of camp Jupiter. "The Tyrant's Tomb" is the fourth book in the series.
