Путешествие к центру Земли

Verne's detailed descriptions make the subterranean world feel real. I'm curious what sparked his fascination with underground exploration.

Some of the science feels a bit off by today's standards, but it didn't detract from the adventure for me. How did others feel about the scientific elements?

The different perspectives and quirks of the explorers added layers to the narrative. I'm wondering how much Verne based these characters on real explorers or personalities.
