the Borgia Codex is read in a BOUSTROPHEDONIC manner; that is, in a meandering pattern, typically from right to left like the Mixtec codices

That doesn't make any sense. Jackie is right about boustrophedon. The metaphor is that of an ox plowing a field, starting in one direction and turning around at the end of a furrow and coming back in the other direction on the next furrow. Whether a marching band would do that would depend on a lot of things. Meandering would be the same thing as boustrophedon but not as tight. The metaphor there is of the Meander River, which flows in great curves across a plain turning back on itself, but not in a tight pattern that covers all the ground in the manner of an ox plowing a field.
