"Marcos Grigorian’s Earthworks are reassuring, relating heaven and earth, spirit and matter, in the most direct ways. Out of the deadness of the earth emerges life, and its soil and golden straw are symbols of life and of the sun. The union of the two factors, spirit and matter, and their becoming one is the first step in creation. He also makes reference to sacred geometry and esoteric teachings in the use of the square and the circle. The square becomes the symbol of the earth, and the sacred four is constituted by manifestations emerging from a fusion of the three elements: will, love and active intelligence. Marcos Grigorian's Earthworks can be read as esoteric symbols of the essential unity of the universe."
