Questions this course answers

What does the title primarily measure?

A league is a distance unit; the title refers to the route traveled under different seas, not a single depth.

Why is the Nautilus both a scientific platform and a prison?

The submarine gives its passengers access to remarkable observations, but Nemo holds them aboard against their will.

What does the giant squid episode add to the novel?

The encounter combines real natural-history interest with danger that the Nautilus cannot simply engineer away.

Why is Captain Nemo morally complicated?

Nemo's independence and opposition to oppression coexist with secrecy, captivity, and violence.
