SHADE OR SHADOW.
“The ghost or phantasm seen by the dreamer or the visionary is an unsubstantial form, like a shadow, and thus the familiar term of the shade comes in to express the soul. Thus the Tasmanian word for the shadow is also that for the spirit; the Algonquin Indians describe a man’s soul as otahchuk, ‘his shadow;’ the Quiché language uses natub for ‘shadow, soul;’ the Arawac ueja means ‘shadow, soul, image;’ the Abipones made the one word loákal serve for ‘shadow, soul, echo, image.’”—Tylor’s Primitive Culture. Vol. i., p. 430.
