The main evidence of who Ishmael is—and by extension his
reliability as a narrator—takes place during the first part of the story where
he actually talks about himself and his actions. After that, he sort of fades into the
background.
Ishmael’s relationship with Queequeg seems to me strange,
because of Ishmael’s initial reaction. It’s almost as if he’s a greenhorn, with no experience of the sea and in
awe of everything around him, especially those of different cultures, rather
than someone who has been to sea before—as Ishmael claims. And yet if I disregard Ishmael’s assertion
that he has been to sea before and is
simply looking for a different ship, then that may explain his complete ignorance
to seafaring life, but not his immediate acceptance of Queequeg as a friend and
equal in a time when a colored man would be treated as a servant or property.
