Abstract

A very clear mirage observed by Scoresby in the Greenland Sea shows an inverted ship floating above the horizon. This mirage can be mathematically reconstructed using a linear image diagram. Scoresby's description is here re-examined: anew set of essential assumptions is distilled from his report, and an ‘exact’ reproduction of the mirage is obtained to match these conditions.
