Voynich Stars

[MarcoP]

These are the stars illustrations mentioned by Sam and Koen above: Bamberg Msc.Patr.61f.79v and BAV Urb.lat.67 f124v.
   

It seems that in this thread the fact that several Voynich stars appear to be "tethered" or "tailed" has not been mentioned yet. This feature appears in You are not allowed to view links.

A reference to a similar idea appears in You are not allowed to view links. Register or Login to view.a (G. Maspero). Bold mine:

[The Egyptians] imagined the whole universe to be a large box, nearly rectangular in form, whose greatest diameter was from south to north, and its least from east to west. The earth, with its alternate continents and seas, formed the bottom of the box; it was a narrow, oblong, and slightly concave floor, with Egypt in its centre. The sky stretched over it like an iron ceiling, flat according to some, vaulted according to others. Its earthward face was capriciously sprinkled with lamps hung from strong cables, and which, extinguished or unperceived by day, were lighted, or became visible to our eyes, at night. Since this ceiling could not remain in mid-air without support, four columns, or rather four forked trunks of trees, similar to those which maintained the primitive house, were supposed to uphold it.

The illustration in Maspero's book represents the night sky in a way that is somehow comparable to the starred-canopy at the centre of the rosettes-foldout. I am not sure this reconstruction is reliable and of course it would be interesting to find a similar image dating to an earliest time than Maspero's book (1900 ca).
