Six onion-roof towers supporting heavens

[Jorge_Stolfi]

This would be a good line of investigation if we were certain that these represent towers. Here they are with a couple of vessels from the pharma section:

Indeed it is hard to dismiss the resemblance as coincidence.

those six objects would have massively exaggerated proportions if they are interpreted as purely architectural.

You mean the other way around: comparing with all the other recognizable elements on that page, if those things are vessels they would have to be of cosmic proportions ...  I find it easier to believe that the center of the Cosmos, according to the VMS Author, had six fantastic towers reaching all the way to the starry sphere, than six impossibly huge drug vessels...

But maybe you mean that those onion domes are too big compared to the tower below them?  That may be the case for some You are not allowed to view links. Register or Login to view., but Russian ones You are not allowed to view links. Register or Login to view..  

Indeed the resemblance with Russian domes seems to be more precise than with those Pharma vessels or with the "Jerusalem" towers of medieval manuscripts.   And all six objects in the Rosette look like towers, whereas only some Pharma jars look like them. 

Other features that match Russian towers are the inverted-trumpet-like spire, delimited from the onion itself by a thin band, transfixing a sphere and ending in a sharp point; the round (rather than square) two-story body, the marked ribs on the onions...

All the best, --stolfi.
