I'd say that the direction of propagation is a significant factor in regard to *what* it is that was being propagated. Also, that the pointed side inicates the direction of origination.

Well, the direction of propagation is not inconsistent with them representing water waves. Ultimately the direction of propagation and orientation of the waves in all maps of the time is pretty arbitrary, but that doesn't stop them from being maps. I could make the same kind of objection to known medieval maps.
