One of the names of the Eskimo moon god. In Alaska Igaluk is the supreme deity: he directs natural phenomena. Under his authority are all the creatures that elsewhere belong to the sea goddess Sedna.
The Eskimo people of Greenland say that the sun and moon are brother and sister. Once in the winter, long ago, during the Arctic night, people began to sport in the igloos, with the lamps out. Then one by one the men took outside the women they had been with, and lighted torches to see who they were. Thus it was that the moon man discovered his playmate had been the sun woman, his own sister. In horror the sun tore off her breasts and threw them down in front of the moon. Then with a flaming torch in her hand, she rose into the sky. Her brother chased after her, but the torch he carried went out, so that it only glowed. Now they have a house in heaven, divided into two rooms; and the moon has not the brilliance of the sun.
