Presumably at the Coliseum was a similar hinged roof. That is, this rosette depicts the process of collecting rainwater from the roof ( of tent).
The artist is has combined view from the top, and isometric, so in the background is not painted drops, and from the front flowing "stream".
Thank you, Wladimir!
The design is very similar indeed. The central "pole" is there both in the You are not allowed to view links. Register or Login to view. and in the You are not allowed to view links. Register or Login to view. of the "umbrellas". This is something I had missed and that clearly is extremely relevant.
PS: the 1945 paper "You are not allowed to view links. Register or Login to view." by Karl Lehmann traces the history of the "sky canopy" design through the centuries. There are interesting similarities and differences with the objects observed in the Voynich manuscript.
