Jules Verne's Captain Hatteras in Arctic Cave by Édouard Riou, 1866

Surprisingly intimate for an age obsessed with grand spectacle, this engraving captures a solitary bearded explorer hunched over a candlelit table inside a rough-hewn cave or ice-grotto, surrounded by scientific instruments, specimen jars, and expedition supplies. The dramatic chiaroscuro and cramped subterranean setting evoke both scientific obsession and polar isolation. The monogrammed 'RB' or 'OB' lower-left signature, the cross-hatched engraving technique, and the 'LAPLANTE' engraver credit suggest this is original artwork from a Hetzel edition of a Jules Verne adventure novel.
