Rosettes as a ... magic altar

[Rafal]

Just yesterday I found a nice match of a magical altar and Rosettes

It comes from The Key of Solomon: You are not allowed to view links. Register or Login to view.
It's 19th century printed edition but the imagery is probably much older

   

   

The circles in the altar are signed "Censer". As a non-native English speaker I had to check this word and a censer is a vessel used to generate smoke during religious or magical ceremonies:



Actually I don't think the Voynich Manuscript owner really used censers with Rosettes. The parchment would get instantly dirty from the smoke and you couldn't clean it. But he could be inspired by such or similar design.
