Final answer:
The provided excerpts do not correlate to the question about the four things the Oracle tells Percy. They appear to be from different sources and do not contain any clear statements from an Oracle directed to a character named Percy.
Step-by-step explanation:
The question seems to be about the four pieces of advice or prophecies that the Oracle tells to Percy, a character presumably from Percy Jackson's series or a similar work of fiction. However, none of the provided excerpts clearly contain four distinct statements from an Oracle directed to a character named Percy.
Instead, the excerpts appear to be from different classical and literary sources that discuss various themes such as wisdom, sorcery, the fickleness of fortune, and skepticism towards divination. There is also mention of Percy, who seems to be informing someone that they are to see something unlike anything they've seen before, but it does not detail any particular message from the Oracle.
Due to the need for an accurate response with the information given, and because the excerpts do not appear to correlate to the question asked, it is not possible to provide a list of four things that the Oracle tells Percy based on the provided reference material.
