Okay, and a ‘dubious’ explanation:
I noticed this when I traced the lettering to understand whether it was thought backwards and written forwards (copied):
Mirror writing and backwards reading have already been discussed at length.
If you mirror ‘aiin’ (knowing that the ‘n’ can also be a “d”, see above) and do not mirror the ‘d’, you get:
Duo
aiinb would then be the abbreviation for duobus.
If you like, you can develop a counting system from this:
ain = unus
aiin= duo
aiiin= tres
@ Rene – if you then add your list, you have a possibly complex number system.
Unfortunately, however, this fails because unus does not occur very often in Latin texts, which is a shame, as it would have been very elegant, as it contains Roman numerals....
