Afrum II, the tetrahedron portrays a three-dimensional shape cut out of the two-dimensional plane of the wall.
In this work, the artist uses a different shape - a tetrahedron - as the template that shapes the light within the space. Like the cube in James Turrell is one of the most celebrated American artists working today. Born in California in 1943, he grew up with an enduring love of aviation and the sky, as well as a fascination with light. His Quaker background also substantially formed his approach to life and art, with its emphasis on silent access to the "light within." From age six, Turrell was urged by his grandmother to "go inside and greet the light" at Quaker meetings. In the early 1960's, Turrell studied perceptual psychology at Pomona College, taking additional classes in other scientific disciplines, such as mathematics, geology and astronomy.
