The Tepenecz signature in book no. 4: a concern

[Kestrel]

Could someone please explain what the concern is?

The concern is:

(i) that "No 4" in the 1553 Dialecta Aristotelis, to my mind, looks self-conscious and unnatural, which are potential characteristics of forgery;

(ii) that "No 4" in the 1553 Dialecta Aristotelis does not share a characteristic of "No 7" and "No 18," in that it is not terminated by a dot;

(ii) that "No 4" in the 1553 Dialecta Aristotelis does not share a characteristic of "No 7" and "No 18," in that it has a double stroke instead of a single stroke;

(iv) that its double stroke, despite initial appearances, is not in fact supported by the evidence of the Voynich MS, since (in my view) that too has only a single stroke.

These considerations, I think, permit legitimate doubts as to the genuineness of the inscription in the 1553 Dialecta Aristotelis.

If in fact the Voynich MS only has a single stroke - just like "No 7" and "No 18" -  then the question arises as to why "No 4" is the only one to have a double stroke. The fact that the Voynich MS superficially appears to have a double stroke may have something to do with the answer.
