Figure 271.—Evolution of the Mangaian triple triangle. a, b, double loop technique, Austral Islands; c, d, triple triangle, Cook and Society Islands; e, f, Mangaian triple triangle, Mangaia. a, front: lower (1) and upper (2) loops. b, side: lower and upper loops crossing on side to form one large triangle. c, front: lower loop (1) continued throughout; upper loop (2) continued for a few turns and then split (3) as shown by crossings in middle line. d, side: split loops in their vertical turns (4) around shaft work inward and by alternately crossing with upper and lower oblique turns create an upper and lower triangle in addition to front triangle. e, front: lower loops (1) persist but upper loops (3) split immediately so that full upper loops of previous two lashings (2) are eliminated. f, vertical turns around shaft that are parallel in d are diverged into two bands (4, 5) and cease to cross with lower oblique series (6) which eliminates lower triangle seen in d; diverging two series (4, 5) cross alternately and create a new triangle (7) below upper original triangle of d.
