Axel Lidenbrock, the teenage narrator of the story, lives in Hamburg, Germany, with his uncle, Professor Otto Lidenbrock, an impetuous and single-minded professor of geology. The story, set in May 1863, opens as the latter rushes home to show Axel his latest acquisition: a runic manuscript by the renowned Icelandic historian Snorri Sturluson. They find hidden within its pages a separate note which, when translated into Latin and read backward, appears to be the Icelandic alchemist Arne Saknussemm's record of a passage leading to the centre of the Earth in a crater of Snaefell, a dormant volcano in Iceland. The crater containing the passage, however, is only revealed by shadows at noon during the last few days of June, just a month away. Otto rushes off to the area, dragging a very reluctant, pessimistic, and skeptical Axel with him.
