New Post: "I Do Listen to the Experts. Do YOU?"

[ReneZ]

Just to stay away from all the speculation, there is one important error in the graph, and there are two interesting omissions.



The error is with Panofsky, whose range is shown as 1510 (blue) - 1520 (orange).

However, his first assessment after seeing and handling the MS in the 1930's was: 1410-1430
Some 30 years later he gave a new assessment, 1470 or 1510 - 1520. The correct range from all this is not 1510-1520. It is 1410 (blue) - 1520 (orange).

The first interesting omission is Richard Salomon, who stated:

it was written in the 15th century, possibly as late as 1450, possibly earlier in the century

So that would deserve a bar of 1420 (blue) - 1450 (orange).

The second omission is interesting in a very different way, but Rich may not have these details. 
Theodore Petersen had written to one of his contacts in the Vatican (A. Strittmatter), who consulted the respectable Mgr. August Pelzer about Roger Bacon in general, and Voynich's Bacon MS. Petersen had sent along some photostats. 
The answer came:

You will be interested also to know that in the course of our first conversation Msgr. P. remarked: 
"Die Voynich HS ist sicherlich nicht von Bacon. Sie stammt aus dem späten 16. oder frühen  17. Jhdt, höchstwahrscheinlich aus der Tschecho-Slowakei oder aus Polen." As I understand it, he considers the drawings representative of interests utterly alien to Roger Bacon.

The German part means: The Voynich MS is certainly not by Bacon. It dates from the late 16th or early 17th century, most probably from Czechoslovakia or Poland.

This could rate as probably the worst of all estimates, from a respectable expert.
Of course, he did not see the MS. Only some B/W photos.

All the rest is speculation.
