In the Middle Ages, it was predicted, God would reveal him-her-it-self, idea-reality-symbol, as a function of one and two, thus the Holy Trinity (conserves the basic circle). Whether one-two-and-or-three is in the middle or on the end, in the beginning or at the edge, the circle is conserved. Thus a perpetual horizon (in human terms) means no horizon (in God's terms). Pi is the universal observer (in mathematical terms). Duplication conserves the unit, thus unification (third, second, first coming).
