Final answer:
The Oracle instructed Orestes to retrieve an image of a specific goddess to appease the Furies, but the necessary details for answers, such as the goddess's identity or image, are missing from the provided fragments.
Step-by-step explanation:
The Oracle advised Orestes that, to rid himself of the Furies' torment, he had to retrieve an image related to the goddess. The specific goddess and image of the goddess are not clearly defined in the fragments provided, and thus cannot be directly ascertained without additional context from the source material.
In Greek mythology, the Erinyes, or Furies, were deities of vengeance who hounded those who had committed certain crimes. In the case of Orestes, they pursued him because he killed his mother, Clytemnestra, to avenge the murder of his father, Agamemnon. This course of action had both divine support, following the Oracle's advice, and grave consequences, invoking the wrath of the Furies.
