ROS - does the bottom left echo the centre?

[Barbrey]

Considering those four corners as points for the four elements, we can suppose that the "volcano" with the water fontain may mean the Element of Water, the "volcano" with funnel-like top may mean the Element of Fire (maybe, it depicts a medieval torch similar to You are not allowed to view links. Register or Login to view.), the "cloudy tunnel" in the left bottom corner - the Element of Air, so the left top pipes must represent the Element of Earth, however strange it is.
I would note that it must be generally strange that the author doesn't depict fire in any place of the manuscript, only some hints on the light. I often tried to find any signs of the Elements in the VMs, in particular, on the Rosettes page, but if they are there, they are veiled.

I often suspect the illustrator ran out of red or orange paint.  

Just as foundation: I read the rosettes as a relationship chart based on creation myth (I'm a sceptic) in one or more overlapping religions, particularly the hermeticum and Christianity,, showing god in everything, and the relationship of spirit, soul and body and respective reincarnation.  It's remarkably consistent in those terms.

I was particularly caught in the hermeticum by the word "midwife" in connection with earthly elements that nurture the spirit.  Because call them what you will - nymphs, women, degrees, plants, stars, angels, goddesses - the women's pregnant bellies, the things they seem to do, and the things they sometimes carry  say "midwife" strongly to me.  Also the fact they are pregnant might relate to another hermeticum principle that plants and stones and elements are created with the seeds of their future regenerated selves already in them.  So not babies but literally seeds.

All that said, I think the VMS is full of references to fire, because I think those women are elemental "midwives", nurturing, nursing, guiding the spirit through its various physical pathways. Each of their barrels give some indication which element they are the spririt for.    Fire is actually the first element hierarchically.  So I think when we see o followed by an Eva k, we have a symbol for celestial fire, which joined spirit to form (o lines to straight lines).  O followed by Eva t is possibly earthly midwives to symbolize earth and water spirits together, and o followed by Eva f is the air.  Look along the top row and you can see where each one is introduced.

Air is introduced a little below the third sphere because it also represents the breath or "word". See how those c's flow up in that air umbrella?  And then the c shape in the middle of the third sphere formed of words?  

I'm pretty sure that c represents the Word of god, which in turn represents Jesus or resurrection or just naming things.  That's why I see air there.

I can rattle on but will stop here.  It is hard to keep to one topic because literally everything in that chart is related, in myriad ways, and as that's the main precept of hermeticism, I don't think that's accidental, but rather its main point.
