the oglala invocation 1907 stained oak framed sepia print backed 8x10

Invocation is more than a formal call to order; it is a creative and professional summoning of the "Wakan Tanka" (The Great Mystery) and the "Tate Topa" (The Four Winds) to bear witness to human action. It is the spiritual infrastructure upon which all significant tribal events—from the sun dance to the council fire—are built.
