artificial horizon

The Sailor's Word-Book

An artificial means of catching the altitude of a celestial body when the sea horizon is obscured by fog, darkness, or the intervention of land; a simple one is still the greatest desideratum of navigators. Also a trough filled with pure mercury, used on land, wherein the double altitude of a celestial body is reflected.
