Triple convergence

[julian]

I see it a little differently. The Roman example requires only one symbol to be in a certain location. The other two examples use two symbols and require a specific distance between them. I'll grant that it's hard to see the purpose. Using substitutions is too simple. However the examples themselves seem to be more complex and therefore less likely to result from random occurrence.

My intent is to point out what the text contains in the hope that discussion might lead to further insights.

There are other sequences on other folios:

• f49v has several sequences, and the inverted v doesn't appear in the fifth position in any of them
  
• f66r has several sequences: none of the fifth positions show inverted v
  
• f75v (right hand margin) has a sequence whose fifth glyph is not inverted v
  
• f76r sequence: no inverted v in fifth position 
  

So, if you were looking for a symbol representing "5" in those, you'd be out of luck. The point being that you are focusing on the only symbol that sort-of matches its position in only one of many sequences in the manuscript.

Having said that, who knows? Perhaps the inverted v really does mean 5?
