Culture 11: Ethiopian cross

Many of the processional crosses of Ethiopia can be simulated with a three-fold iteration. While they are now used by Christian church proceedings and have symbolism involving the Trinity, related designs can be found on ornaments excavated from the city of Axum in Northern Ethiopia in the second half of the first millennium B.C.E.—more than 300 years before Ethiopia converted to Christianity. Which lines in the simulation are passive and which are active (self-replacement)?
