Final answer:
The student's question references what a prophet does before telling Agamemnon about plagues; various mythologies and classical literature depict prophets or omens advising leaders, with diverse responses advised or taken.
Step-by-step explanation:
The student asked what the prophet does before he tells Agamemnon about the plagues. The narrative provided refers to several stories from different cultural mythologies and classical literature, where prophets and omens play crucial roles in foretelling events related to plagues. In the tale involving King Bocchoris and the oracle of Ammon, the king is instructed to expel the Hebrews to avert the calamity.
Within Greek mythology, as conveyed by the tales of Oedipus and Iphigenia, prophets like Tiresias deliver dire news but often suggest that certain knowledge should be left hidden. The Biblical references, such as the plagues in Egypt, notably do not mention a prophet informing a ruler like Agamemnon directly, as the events occurred before his time.
In Greek tragedies that refer to Agamemnon, prophetic information usually comes through oracles or seers rather than direct intervention by gods, and any interaction with Agamemnon specifically would be depicted within that narrative framework. The figures who receive or deliver prophecies handle them in various ways, sometimes being advised to heed omens, change behaviors, or even to ignore the fateful knowledge altogether.
