From the press release for the now closed, "Ends of the Earth" exhibit at the Peabody Essex Museum:
"This breathtaking, 7-foot-wide oil painting depicts the northern
lights as a brilliant curtain of turquoise, orange and yellow across the polar night sky. Church had journeyed to Labrador and Newfoundland in 1861, searching for icebergs to paint. He created Aurora Borealis, enhanced by his own imagination, in order to convey his quest for the sublime in nature."
