Journey to the Center of the Earth · Chapter
XVIII: The Wonders of Terrestrial Depths explained
Axel and his companions awaken at the bottom of the crater and begin their descent into the earth's interior.
What happens
Axel and his companions awaken at the bottom of the crater and begin their descent into the earth's interior. They retrieve their dropped bundle, take scientific measurements, and marvel at the crystalline lava formations illuminated by their electric lamps. After seven hours of descent, they stop to rest and calculate their depth, discovering they are 10,000 feet below sea level—far deeper than any previous human exploration—yet the temperature remains surprisingly cool, challenging prevailing theories about underground heat.
Themes in this chapter
Scientific Curiosity and Ambition
The Professor's meticulous measurements and calculations, along with Axel's reasoning about geothermal gradients, demonstrate the drive to understand the earth's hidden depths.
The Unknown and the Sublime
The crystalline lava formations and the vast, silent tunnel evoke awe and wonder, as Axel describes the scene as if 'the genii of the depths were lighting up their palace.'
Characters to notice
