The Voynich Pipes

[Anton]

The first point I noticed is that the star divides the sky in eight parts. This is the case in a number of other charts in this section. Perhaps this eight-part system corresponds to the 24 hours? (24/3=8)

Maybe the pipes represents measurements one can/should make? Just looking at the pipes, if you see what they are "looking at", it's usually an alignment of stars (in the blue section).

There are six divisions in some VMS charts instead. And how number 8 would refer to 24 hours, unless the author was a working class activist ("8 hours to work, 8 hours to sleep, 8 hours spare"), I fail to understand  

Not the pipes themselves are strange (in the German article there are examples of charts without pipes, so pipes essentially stand for something that could be represented without involving pipes), but the alternation in their length.
