Question

Which part of this excerpt from Homer’s Odyssey depicts Ulysses revealing his true identity to his faithful servants Eumaeus and Philaetius?

Answer 1

I think you are talking about an Odyssey excerpt? If so, then the part you are looking for would be:

"His ragged vest then drawn aside disclosed
The sign conspicuous, and the scar exposed:
Eager they view'd, with joy they stood amazed"

This depicts the reveal of Ulysses clearly.
