Did Arne Saknusemm real

Arne Saknussemm is a fictional character from Jules Verne's novel "Journey to the Center of the Earth." He is depicted as a 16th-century explorer who discovers a route to the Earth's core. While the character is not real, he serves as a significant plot device in the story, guiding the protagonists on their adventurous journey. Thus, any references to him outside of Verne's work are purely fictional.
