Discussion of Yulia May's proposed solution

[ReneZ]

I also don't want to be overly critical, and the following comment equally applies to anyone looking for the solution.
As mentioned already before, I think it is important to look also at the 'encryption' step, not only the 'decryption' step.

In the above case it means that, whoever wrote the MS, could have encoded the plain text word 'omnius' as otol , but also nepos and nubens would become otol .

I find that hard to imagine...
