Completed in New York that winter, Aurora Borealis was exhibited publicly in London in 1865 as a triumvirate with two paintings by Church of Ecuadoran volcanoes: Cotopaxi (his 1862 painting of an eruption) and Chimborazo (his 1864 reprise of the dormant mountain that had been the subject of his 1858 masterwork Heart of the Andes).
