Gallows Island

[Jorge_Stolfi]

As Currier observed, many Voynich glyphs look like Latin letter used in medieval European scripts, letters such as a, c, d, e, h, i, l, m, n, o, r, u, v, z, however the Germanic letterforms k, t are missing, therefore, it is reasonable to assume that they stand for k and t. T[...]

I don't think that the Voynichese alphabet was meant to resemble European letters shapes at all.  To me it is obvious that the Author created the alphabet from scratch by systematically combining pairs of simple strokes.

   

(In the above table, instead of the ligature line,  the last column should be for h, which counts as a single stroke too.  Combined with e and i on the left, it generates Ch and Ih, which are reasonably common glyphs.)

The primary concern of the Author apparently was to make the glyphs easy to write with a quill pen on vellum, which is best done with the pen moving in directions between Southwest and East for right-handed writers.  Since he was not bound to the Roman letter values, he probably tried to assign similar glyphs to similar sounds, much like the creators of the You are not allowed to view links.
