Interesting Match

The final "s" were written like a Greek sigma, in a single stroke like a 6, Other "s" were written in the long form.

The word is "duas", two in the accusative plural feminine... it can't be the most common word of any text.

Perhaps while writing the VM letters, the slant of the S would match the overall slant of the word for convenience.  The way cursive tends to angle according to the position of the hand of the writer.

Could it be very common if the text was about duality of a property, of a form, yin/yang, duality of different types of things, or instructions to do something twice?
