The Voynich Pipes

[Anton]

and different "markers" (pipes instead of "nails")

I'm not sure that Voynich pipes are not nails. Note that the shapes are not strict cylinders but rather cones, so they indeed look as nails without heads, and the heads may be intended by the green colour of the upper faces. So these could well be awkward nails - especially if the pattern was borrowed, and the Voynich author did not realize that those are nails.

I think what we can be certain in is that the nails are no more than four in number - because Christ was hanged with no more than four nails. So 24 points cannot be 24 nails. At most, they can be four nails "in motion" - in other words, 24 positions (clavorum positio!) which the four nails occupy sequentially in time (as the sky dome rotates).
