I selected these materials because stones are immutable, i.e., ten years from now, a hundred years from now, a thousand years from now they will still be essentially what they are today. However, their outward appearances may be altered a little bit depending upon what circumstances they face over time. This to me seems equitable with the varying representations of these figures throughout time. Their essences seem to hold static, but their outward appearances and some of the minor interior nuances have tended to shift over time and between cultures. So, the selection of this medium, seems to me, more than satisfactory to represent how these figures are and have been represented differently by different peoples.
In regard to the selection of crystal to represent the Christ, as you can see, the light shines from a source beyond through unto the audience. In all the representations of the Christ that I have been acquainted with is the theme of the Christ being the light: “In Him was life; and the life was the light of men. And the light shineth in the darkness; and the darkness comprehended it not” (St. John, ch., 1. vs. 4-5). This seems to be very consistent, i.e., the Christ is represented as shining light onto the world. A common and more traditional representation of this is the use of the halo and the crystal medium functions as a comparable representation of this.
