Two tubes coming out of the star-studded celestial globe. They are the same tubes that we see in the Rosette folio.

I think those are poles on Tratado f88. North and south poles.

The VMS structures appear to be tubes, they are drawn with dark centers, and they point in multiple directions, and are in clusters. They are quite different from the ones in the Tratado, and don't appear to be the same thing.

I don't know what they mean in the VMS, but I saw one manuscript in which steam vents were drawn as pipes. Ellie has pointed out that pipes are also used for cannon barrels/gun barrels, and gunpowder (saltpeter) containers. Pipes have many meanings in medieval manuscripts.
