The knotwork in the center of the cross is a triad, which symbolized the trinity Father, Son, and Holy Ghost. At the four points of the cross are rams horns, which are a variation of the spiral. The spiral represents the cosmos or God with all things revolving around Him. The leaves around the center of the cross possibly represent the Tree of Life.
