What is unique or rare about the VM Zodiac signs?

Hello JKP thanks for the detailed comments, you seem to have access to many different sources.

I also just discovered your blog so I will have to catch up with the current state of the VMS investigation.

Also feel free to avoid this question if it's redundant or it has been answered before, but is there a concensus on why the VMS has two sections dedicated to aries and taurus? Are there other examples of manuscripts where this happens with these two particular signs?
