Catalog of Crosses
Unlike the vertically elongated Roman cross, which it predates, this figure— still widely used in Eastern and Orthodox rites—has four arms of equal length. Before the advent of Christianity, this design symbolized, among other ideas, the four directions of the earth. Later, it became an emblem of the four evangelists and their gospels. I have hand-drawn an original pencil sketch of this iconic shape inside each copy of X Crosses.
