For example, the question "are they pipes at all?" is still open. We can assume with some certainty that at least within the same subset of folios, the same visual conventions are used, so comparing these diagrams can teach us something. Don't ask me what at the moment
About the "sighting tubes", by coincidence I read today that at least the Greeks used them to reduce light pollution, i.e. to really be able to focus on the light of the stars.
I don't have any feeling that all those (as listed by Marco) belong to the same class. Instead, 77r - 78r look more like "vessels", which 69r and 69v do not at all. So the diagrams are simply not "similar".
Of course the question "are they pipes at all?" is open (like I supposed above that these may be nails instead). But the foremost question in respect of You are not allowed to view links. Register or Login to view. is what could the object set (numbered at 28 and linked to the celestial dome) stand for.
